Hey guys, I was hoping to get some input on what this clunking I've been having can be from.

When I'm driving on the power and then let off of the throttle, my car lurches and makes an audible clunk. Sometimes it goes back and forth for a while. It seems to happen more severely when it is colder out.

I've changed the rear pillowballs, motor mounts and diff bushing recently. What else could cause this drivetrain clunk?

Thanks for your help,

Kevin

drive shaft possibly. you'll need to look at the both ends to determine if the ujoints are worn.

it could also be backlash in the diff is out of spec

I had a similar experience including the springy or bouncy feeling and it turned out to be a crack near the front of the PPF. It is repairable by welding.

Be advised that some cracks may not be visible while inspecting the PPF on the car. I missed the one on mine during the first go round.

Definitely sounds like a cracked PPF

Yea, that's what I'm going to bet on at this time too. Thanks for the input guys.

I'll let write back once I find out what it is.
