Ok so after filling the rear axle with fresh fluid and a new cover, the axle is still junk. I am speculating a pinion bearing is toast. I took a video of it making racket and presented it to my axle and transmission guy, he agreed that it sounds like a pinion bearing and not to drive it (duh).
I asked what his labor charge is to do the rebuild, I supply the parts, he told me $200. Needless to say I am going to use him, he is ASE certified and OCD about doing stuff right the first time.
I have driven this car a total of 4.5 miles since buying it, I am pretty frustrated at this point. I am just going to pull the trigger and buy some 3.73's and be done with it. I might put in an aluminum driveshaft as well, that would take care of u joints, or is that a really dumb idea on a stock car? Obviously just buying u joints are waaaay cheaper, but is there an advantage to buying an aluminum drive shaft?
01 GT "Old Yeller" rebuild in progress
94 Ext Cab Z71 5 speed. Way too many mods and way too much money spent, and still not done yet.
