Hello All, ever since i swapped driveshafts to a 1 piece aluminum and back to stock, as well as doing the upper control arm with an adjustable unit, upper bracket, and rear diff bushing I'm getting a clunk.
Car stats for reference
2005 Mustang GT 5 spd
DOB supercharged
25,000 miles
Parts used
Metco ADJUSTABLE UPPER CONTROL ARM MOUNT
J&M ADJUSTABLE REAR UPPER CONTROL ARM
Steeda Spherical bushing for the Diff side
All new bolts and hardware
The clunk was not present before the mods were done, and the clunk was present with the aluminum driveshaft, so i know its not the stock driveshaft.
Basically if i blip the throttle in any gear I will get a clunk sound, sounds more like metal then like a loose/worn bushing. Also in between shifts if i shift slowly i get the same clunk. Almost like its driveline slop in the rear end itself.
My Mechanic buddy who did the work just zipped off the pinion nut and zipped it back on. He says that he has done hundreds of rear ends and never had an issue. He also said that he didnt torque it enough to crush the collar more. He also said that the spider gears could be worn, or my clutch packs worn out.
We put the car on the lift and he turned the rear wheels and it does look like there is some play in the rear end, he also tried to turn both wheels while i held one, and said that since i could that the lsd is worn out.
Today just to test that theory i found a spot and did a quick burn out, I am still putting down 2 strips, so the lsd seems to be working.
Sorry for the book, but any ideas? Could he have messed up my gear lash causing extra slop? if the spiders and clutch packs were worn would i still be able to lay 2 strips? Could something else be making the noise? Or is it somewhat normal for there to be some slop and clunks
