Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Has the mechanic been able determine where the clunk is coming from? Does it do it during power-braking?
I'm sorry, but I need more information in order to make an assessment. I'll opt out so others may try. Don't reply until another expert responds or the site will cycle this back to me.
another expert here this sounds like a worn mounting - check the tightness of the engine and gearbox mounts and their condition - this is best done by using a jack to take the weight of the engine off the mounts and seeing if any cracks or splits open up in the rubber.Also check the tightness of the mounts bolts
do you still need help?
