Hi! I have a 2000 manual OBW, 201k miles. I just had the transmission rebuilt and the timing belt replaced and picked it up today. On the drive home from the shop, after about an hour, I turned into a parking spot, and heard & felt this thud thud sound. I've heard this sound before when turning, years back and believe it was the CV boot (not sure which?) and had my mechanic fix it. That was in my previous state. Now I live somewhere new and had a new shop do the trans rebuilt and timing belt (broke down while on vacation, so went with a referral). I plan to call him on Tuesday when he's open, but my question is this:

can doing a trans rebuild/replace timing belt, mess something up inadvertantly to cause this thud/clunk sound when I'm turning? The sound isn't there when going straight. It's loud enough to have made me look a the tires thinking I had a flat or low tire. Yes, I need to get my tires rotated and will do that Monday. I know the guy who worked on it is great, so is this a coincidence that something new went wrong on the way home from the shop, or did something get bumped during the rebuild? I'm a total novice on cars and their workings, so I'm just trying to figure how if this is a new issue, or related to the rebuild. I ask because the shop I had it worked on while I was on vacation, is 2 hours from my home, so not easy to just take it back and drop it off with the same guy. Obviously if it is related to his work, then I will find a way to get it back to him to take a look at.

Thank you.

I see no reason not to approach they guy and let him know your concerns about the noise. Could you duplicate it for him?

 

Anyone can make a mistake and  - I dunno - fail to install the axle pin or fully seat the stub axle, or leave a bolt loose, etc.If it IS exactly the same noise you've heard before, it might be something unrelated to the work he did and also something he may not have inspected - like a broken anti-sway bar or some bad bushing in a suspension part.

 

Do you feel any bucking/jerking when turning tight on dry pavement? After a run on the highway? Are the tires all the same brand and wear?

My experience with subarus with 4eat automatic transmission will do this while turning tight circles. Sometimes more pronounced than other times. This would be a function of the duty c solenoid/rear drive clutches. 

 

First of all make sure all the wheels are the same size and brand, inflated the same, and all wheels are within 1/4 inch circumfrence of eachother.

Manual trans, so no duty C.

 

If they put a rebuilt center differential in it while they rebuilt the transmission, the new diff could be binding. It sounds exactly like the torque bind issue you get when the center diff fails. Good news is it's a 1 day job to change out the center diff and they don't need to pull the transmission to do it.
