I'm getting a clunk seems to come from the middle of the car, just behind the engine area. It started off very minimal but is getting worse as time progresses, especially on acceleration, braking, and turning. Also when stationary I get the same sound when shifting back and fourth between reverse and drive. It's an older car but I've been replacing one thing at a time and would like to do my engine/ transmission/ differential mounts to get rid of the clunk and take up any driveline slack. Would somebody be able to give me a parts list of what I should be looking at? Brands? Websites? Don't have a ton of money but don't want to buy garbage either. I'm an auto tech apprentice so I have access to a full shop and will be doing this on my myself. Car is an 01 a6 4.2 sport suspension. Any guidance in the right direction is greatly appreciated. Thanks!
