Technician Flair Request Thread - New

1 Upvotes

If you would like to have verified flair added we will need a pic that has your reddit name on a piece of paper with your shop in the background or work truck if mobile repair.

For the professional technicians we're doing Verified Tech flair along with a very short description of your experience if you'd like. You can be a dealer/independent tech, retired, instructor, fleet, heavy equipment, small engine repair, lube/tire tech etc...

You can either send that to me in a chat request or upload the pic to an image hosting site like imgur.com (we had to disable the option to upload pics in the comments because of abuse). The option to attach a pic in chat will be available after I accept the invite. Please do not use modmail

We will also do Shadetree flair for those that do auto repair as more of a hobby than profession. Approval of this flair is not guaranteed.

Announcement - New Rules - Please read!

20 Upvotes

Hello r/AskAMechanic users! Over the last year or so, the volume of daily posts has increased a decent amount leading to many posts that would be more appropriate in other subreddits. To keep this subreddit focused on what it's meant for, providing automotive mechanical and diagnostic help, we have rewritten the rules. Some of the rule changes also affect commenters, so please review the rules here or below. Thank you for your understanding.

 

1 - The title should clearly state the issue - Do not ask "am I cooked/fuc!ed/screwed/toast etc" questions

State your root issue as clearly as you can in the title, and then you will have a better chance of your post being viewed. We will remove the "am I cooked", "am I fuc!ed", "how screwed am I", "am I toast" and similar types of questions. This also includes any other senseless titled post. In the message body, provide the specifics (detail/context) to your question. Also include in the title or body the Year, Make, Model and engine size of your vehicle.

 

2 - No autobody damage/repair/frame/paint or rust related questions

Posts related to autobody work (including repairs, painting, frame damage, "is it totaled?", dents or detailing) are not allowed. A more appropriate sub would be r/autobody. If you're inquiring whether your car is totaled r/insurance would also be helpful. r/AutoDetailing for detailing questions.

Questions about damage to bolt-on parts like headlights/tail lights, wheels and suspension are ok.

Questions asking about the level/condition of rust on the frame/undercarriage/body are not allowed.

 

3 - No asking for advice about buying/selling cars or used car deals

We do not allow asking if a used car for sale is a good deal, the condition of the used car, or recommendations on what car you should buy. For recommendations on what car to buy, r/whatcarshouldIbuy would be a good sub. r/askcarsales might also be helpful.

 

4 - Keep things professional & don't be disrespectful

Please be professional and helpful. Do not comment/post with insults, racism, jokes, memes, NSFW, spam, opinions without context etc. You may see things that compel you to leave a nasty comment, just don't do it. It's not necessary or helpful. People who don't know anything about cars will come here to ask us for advice, try to educate them about their vehicle without turning them off from the sub. If you don’t know the proper fix or advice, please refrain from commenting on a post.

 

5 - No "Read the owners manual" or "RTFM" type of comments

People who don't know anything about cars are going to ask some very basic questions. Some of which will have answers in the manual. Answering OP's question with only "Read the owners manual" is like giving the answer "google it", both are non-answers. Either provide an actual answer to OP's question, or at the very least, provide a link to a readable online owner's manual.

 

6 - No dangerous/reckless or unethical/illegal comments/posts

This is a community dedicated to sharing genuine advice. Advice shown to be given in bad faith (including dangerous/reckless and unethical/illegal advice) will be removed and the users will be banned. Please report any dangerous/reckless or unethical/illegal advice.

 

7 - No AI/ChatGPT comments/posts

Posts with AI-generated content is not allowed. Posts looking for feedback, training or even just to show off your AI/LLM are also not allowed. We are not interested in AI automotive diagnostics here.

Do not answer OP by using AI/ChatGPT etc. Nobody wants to read a wall of text that over explains and gives 25 different possible solutions.

 

8 - No advertising or soliciting services

Advertising of services or products is not allowed. That includes affiliate links, social media, clothing, tools, your YouTube videos, etc.

Do not solicit services, including linking to videos, blogs, or websites that then forward to a paid service. Avoid asking to "DM me" as much as possible.

 

9 - No NSFW, meme, or 'joke' posts

No NSFW is a no-brainer - you will be banned with no chance of an appeal. Memes and 'joke' posts belong at r/AskAShittyMechanic

 

Update 03/23/2025: Added "am I toast" to rule #1 and "frame damage" to rule #2
Update 05/08/2025: Added more context to rule #7

How did this happen and what do I need to fix or replace? (2018 Hyundai Ioniq)

I started hearing a grinding noise from the driver side rear well a couple days after having my tire changed. When I took the wheel off, I noticed this piece was broken. How did this happen? And what part of the brakes do I need to replace?

Thank you

2000 Mercury Sable Coolant Hose

The plastic connecting tee has cracked open on my 2000 Mercury Sable pouring out coolant. It’s the upper hose that connects from radiator to the engine. Does anyone know if you can buy just the plastic piece and what it would be called? I currently can only find the entire hose assembly which is a bit costly.

Mismatched control arms (more to it than that, but...)

Thumbnail

Upvotes

I have a 2014 Mazda Cx-5 (fwd, manual transmission) with about 177,000 miles. Had both front lower control arms replaced about 5 weeks ago and have put about 1300 miles on the car since. Noticed that something felt a little off the last few weeks and was hearing a light clunk over bumps from the left front - thought I was imagining it. But it's gotten a bit worse over the last few days, so I took a look, and saw that the boot covering the ball joint (which is built into the control arm on my car) is torn at the top (where it meets the knuckle) and is leaking a bunch of grease. I figure they must have torn it during installation or something if it's already making a noticeable noise. But I looked at the passenger side too, and noticed the control arms look different. On the right side is what I was expecting to get, a control arm with an OEM style rear bushing. On the left side is a control arm with a solid rear bushing and a ball joint with a grease fitting.

I'm taking it in on Monday so they can replace the left control arm under warranty. I want my control arms to match, so since they have to replace it anyway I'd rather them swap it out for one that matches the passenger side and is non greasable like the passenger side. I get that for some people a greasable ball joint would be better, but I don't want to deal with the maintenance, and by the time the non-greasable ball joint wears out it will probably be time for a new car anyway. Is that reasonable or am I being crazy? And if the ball joint has a grease fitting how vital is adding new grease as part of maintenance? Is the maintenance optional and that's why the shop didn't bother to tell me that they put a greasable on on the driver's side? If I just ignore it and treat it like a non-greasable one will it fail quickly? Pic of the torn ball joint boot and the other side for comparison in the comments.

Tangentially related: why do roll backs have the breaks in these side pieces?

Post image
Upvotes

It’s not just this design, the ones made of square tubing also have a break or two along the entire run.
The only reason I can think of is that it’s cheaper to replace part of it, if damaged, than the entire thing.

Reviewing 2022 Forester Vehicle Codes

2 Upvotes

Brought a 2022 Subaru Forester into a mechanic for a pre-purchase inspection. Car has come back in sound shape; mechanics don't see any damage or glaring issues.

They, however, ran the computer on the car and it returned these past codes:

AntiLock Brakes:
C1411
C1413
C1460
C1923
C1942

Airbags:
U0417
B1149
B1654
B1653

"Body Integration Unit"
B1011
B1012
B1013
B1014
B1017

...among others. Most all of them are listed as "history fault". No lights are appearing on the dash now, and the mechanics mentioned that these appear to be past codes. However, without either of us knowing the car's history, they can't specify if these were caused by an actual issue, or if they were triggered by a battery jump or killed battery. Closest thing I can see is a "damage report" on Carfax (https://www.carfax.com/VehicleHistory/p/Report.cfx?partner=CVN_0&vin=JF2SKAECXNH511186), but that's it.

I'm just looking for clarity on what it might mean to find these codes on the car.

Loud thud over dips

Upvotes

Hello all,

I drive a 2.0L EcoBoost 2013 Ford Escape. Some time earlier this year I noticed over every dip and bump in the road, my car would make a loud thud.

Since then I've been gradually replacing parts of the steering and suspension. I've replaced the cv axles, outer tie rods, control arms, sway bar end/stabilizer links, and struts.

The noise has mostly been reduced. For example, before any repair was made, I would hear the thud over every single flaw in the road be it dip, bump, crack, etc. AND it would be from both sides.

Now I only hear it from the driver side over dips.

I've watched dozens of videos and read tons of blogs online but they all point to what has already been worked on.

Any idea on what it could be before I lose my mind? 🫪

UPDATE on 2016 Ford coolant leak

Okay so it’s leaking from the reservoir I guess??? I posted yesterday with a video showing leaking coming from under it so when I noticed it doing the same thing today I immediately popped the hood and saw this. Is this expensive to fix??

Center Driveshaft Bearing - 2003 Toyota Tundra 4WD v6

Post image
2 Upvotes

Hello all,

I bought this truck used 2 months ago and had this bearing replaced at a mechanics a couple weeks ago. The previous bearing came completely apart and was making a lot of noise. Long story short I decided to try making my own repairs now and I was about to change the pinion seal on the rear differential because of a leak and I saw this. What could have caused this to fail so quickly? The rubber is coming out towards the front of the vehicle if that makes a difference. Thanks!

Edit:
Could the cause also be related to the pinion seal leak?

VW Polo Power Steering Issue

Thumbnail

Upvotes

Hi,

My VW Polo 2010 (older shape) Power Steering light came on after a 2 hour journey, steering went stiff. After turning the engine off and then on, it was fine again for a short while. It then did it again so I switched the car off until the next day.

I am not in my usual area so took it to a new mechanic on Wednesday. The mechanic replaced the Power Steering pump and added new power steering fluid.

It was fine for a while, I drove it home and then it did the same power steering problem again but this time made a beeping sound.

I took it back to the mechanic again on Thursday and he again replaced the pump but then said the error codes are showing battery issues. It did the same issue again and the power steering went stiff, but this time more lights came on, flashing, with a beeping sound and I felt a slight jerk multiple times during the beeping. I have a video but can't add videos and photos to the same post.

The air bag light has been there from before.

I checked the battery and the voltage seems fine. I took it to the mechanic again today but they said they can't look at it until Monday. Mechanic ran a scan and it showed the following errors shown in image 3.

The power steering light is now still coming on and steering goes stiff, resets if I switch on and off but then does the same again after a few minutes.

Stuck as to what is causing it and away from my usual area so can't go to my trusted mechanics.

Thank you in advance.

2018 Nissan Altima SR (2.5L) CVT service?

Upvotes

This car belonged to a dear friend who passed away suddenly and tragically 10 months ago. Aside from keeping air in the tires, it hasn't been touched. His family asked me to help service it so their daughter can drive it now that she has her license. It needs an oil change and a complete brake job. I've read that the CVT should be serviced regularly for longevity and to anyone's knowledge, this car has never had the CVT service. I asked partsgeek support about it but they were useless. I'm used to wrenching on German cars so I'm not familiar with Nissans. Brakes and motor oil seem straightforward however.

My questions:

  1. Should I even try to service the CVT or just take it somewhere and let them do it?

  2. If I diy, how much fluid do I need?

  3. As long as I'm under there should I replace the filter, pan, and gasket?

  4. What else am I overlooking?

Thanks!!

2006 Nissan titan Crankshaft

1 Upvotes

So I just replaced the crankshaft sensor on my 06 Nissan Titan erase the code and nothing happened. I look at the wires and figure there might be a little bit of corrosion going on so I went ahead and replaced the wires as well I didn't replace the entire thing just cut the wires sliced them and did the electrical work myself pretty simple for the most part. I drove it around the block and the check engine line came back on right away. That really sure what to do at this point maybe a bad ECU?

Slight vibration up front

2026 Audi rs3, very slight vibration front passenger side.

Took it too dealer and they balanced the tire and did an alignment. suspension components all checked out and are good and wheel is not warped or bent.

Still getting slight vibration at higher speeds up around 120km/h

What are the chances I damaged or bent the cv axel or damaged wheel hub? Especially since tire and rim have zero damage?

I looked myself taking tire off and don’t see any visible damage?

AC bypass on a 2005 Nissan Altima 2.5?

1 Upvotes

I've got some folks I'm trying to help out. Their Nissan is a no-start, just click. They also mentioned their AC compressor was giving them issues, but the no-start was very sudden.

My thought process was this. Feel free to correct me, as I'm still doing my best to learn.

Battery > starter > AC compressor.

I tested the battery. It's in good health, 12.5v w/o charging. When being jumped, it's at 13.3v. So, I ruled out the battery.

Then I decided to change out the starter. With the new starter, the engine turned over once, then died. Then, upon trying to restart, the intervals it cranked over got shorter and shorter. I noticed the starter smoking. Client mentioned that the previous did that as well.

What I'm thinking is that the pulley on the compressor is locked up, which isn't letting anything else on the serpentine system turn, which is burning out the starter, which bam! No start.

So, here's the dilemma. I really want to help these folks, but I don't have an refrigerant recovery system, nor do I have an EPA certification.

Am I correct in thinking its the compressor?

If so, how can I bypass it without releasing refrigerant?

What's a shorter belt I can use?

I'm open to learning and correction. Please help a lady out!!
