Diff. Noise
Im just tryin to see if everyone lese agrees with me on this. A freind of mine has an 88' T2. Anytime you get on or off the gas you can hear a clunk in the rear. Wouldnt that 9 times out of 10 be the front diff mount? He said it started overnight, out of nowhere. Just making sure before he does any buying

It's most probably the front mount, and that's easy to check. Jack up the back of the car, get a big bar and lever up on the side of the mount that's bolted to the diff. It's it's broken you'll see it clearly.

the thick plate you see is just the arm that reaches up and forward that the actual mount mounts onto. the actual diff mount itself is just a mediocre size rubber piece with a steel backing where it bolts to the differential itself. much like a motor mount when the rubber weakens it cracks and eventually shears off clean and the unit it mounted to is free to move where it wants, with the differential it basically torques up and hits the bottom of the chassis which is the clunk you hear and feel.

No question that its broken. COuld pry it with a bar as much as 3''- 4'' up from its resting location. Hese also going to go ahead an buy new top mounts while hese at it. While taking the car off the ramps (I brought my ramps to his house to save time, as I was already going over there) one of the ramps slipped on the concrete driveway, and the rear fender got bent a little So now Im going to be fixing it for him and repainting his car soon. Its not bad but I feel bad for doing it. out of the hundreds of times I have used ramps, this is the first time I have ever had this happen. Instead of the car rolling off, the ramp shot out from under the passanger side rear tire... car dropped and I just said oh ****. MY BAD
