I have a clunk noise when i go from a standstill that feels like its from mid to rear somewhere. I have recently replaced the rear diff bushing as well as the mid carrier bearing. When i pry on the tranny at the mount it does have play so im thinking the mount is shot. I also have a good 4-5k vibration which is prob related.

 

Could you post a short video of the noise?

 

Im not sure ill be able to get a video of it. Even if i do its not loud enough to be able to identify it over the other noises of driving and part of it is a clunk feeling as well.

Since i've posted this ive seen used mounts on ebay stating the part is in good working order with documented mileage well above my 87k mileage so im wondering if these things last longer and mines ok. I can take a video of the pry movement and it appears to be loose, but im not taking the chance on a used part and im leary of dropping 150 on a new mount to find this didnt stop the issue or even reduce the 3-5k rpm vibrations im also having.

Im not sure why all these driveline bushings/bearings have apparently worn out faster than usual on my car. It seems like normally they dont go bad until over 100k or more.

 

I would point towards trans mount. If not, maybe a carrier bearing or driveshaft issue. Not sure if this is a problem or even an option on these cars but I had that problem on my previous Lexus. Was vibrating at certain speeds and would clunk etc.

 

If not the trans mount, check the U joints

 

might also be this, I read this a while ago here, makes me think I should check mine. My car has a vibration from the rear :/

Center bearing is new, swapped that out a few months ago. All the u-joints looked ok, but i wouldn't imagine they would cause consistent clunking from stopping and then starting again.. vibration absolutely. The trans mount is the only thing i can think that would move under these specific forces. In spite of the fact these parts should have lasted longer since the diff and carrier bearing were both shot already i gues it just makes sense the trans mount would too.

That looks like a driveshaft flex joint but i dont remember seeing that on my car. I couldnt tell if that guys car was maybe an auto or awd where i have rwd and manual.

EDIT: just re-read and saw he has an auto. This must be what autos use in place of the carrier bearing or maybe its just newer versions, mines an 08 his was 2011.

Thanks everyone for your input
