lots of noob ?
 

ok so i have got about 400kms now on the 924, it had a ppi done it recnetly before i got it , it seems to have a couple of issues that i cant figure out , 1) clunk when shifting ? it feels like either a bad u joint? these cars dont have u joints right? 2) i have a sound of bad rear end that i couldnt hear before cause it had a exh leak , common noise? or death to the rear end soon? i ll check the fluids tommrow at the shop, help!!!! thanks in advance

Check the cv joints on the axle shafts - re-pack with grease.

Uh-Oh Spaghetti-o's!

huh?

Need a little more information.

Where is the clunk coming from? behind the engine, from the rear? and when does it clunk - only when shifting?, when you apply power?

These cars do not have U-joints. They do have a torque tube - essentially a long driveshaft supported by bearings. If one of the bearings is going bad, the car will make a moderate howling noise under load - particularly at certain RPM. Eliminate the wheel bearings as a source first. Then change your transmission fluid and check the fluid - some silvery power (chaff) is normal. Little chunks of metal are bad.

If all of that checks out - it is probably your torque tube - if you can live with the noise, I would suggest doing so. You can pick them up used fairly inexpensively. New, the cost is extremely prohibitive (over $1000 USD). Replacing a torque tube is very labor intensive.

Good Luck

Other problem with the torque tube is it's proximity to the exhaust and the cat. converter. The heat really is hard on the bearings.

The noise sounds more like CV joints, likely on an older 924 since they usually get ignored by the po.
