Topic: Rear end help (the car's, not mine...)
in Forum: C3 Driveline Components
Long story short: dropped the car on the ground yesterday after way too long on jack stands. Neither rear tire will roll. The ebrake cables are slack, and the transmission is in neutral (TH400 auto).
Too much work in the drive train to itemize, but essentially: trans refresh, rear end rebuild, all new poly bushings, rear trailing arm rebuild, u-joints, rotors, calipers, pads, brake lines, composite spring, etc. Brakes are properly bled and are working.
Put it back on jack stands, same result. Removed the rear tires, and everything moves freely as it should. So it's nothing in the drive line. But when I put the tires back on and snug up the lug nuts, it locks up.
Tires and rims are the same as before all of the work, so it's not a rim backspacing issue. From what I can see, the tire is not touching anything and the paint on the calipers isn't scuffed or worn so I don't think the rims are rubbing there. Plus, I can rotate the entire assembly easily if I relax the lug nuts.
Could I have gotten incorrect rotors and/or pads? The pads and rotors were interchangeable front/rear, if I remember... (but it's been a while since I installed them.) Could the rotors be binding against the ebrake pads or the brake pads when they are torqued down?
Could the Corvette Gods be mad at me because I sold my C5? Should I drag it to the road, sell it, and buy a Prius?
Any advice would be greatly appreciated!

(P.S. Just kidding about the Prius! Or maybe not...)

My bet is it is something skwewy with the park brake...too tight, or maybe the shoes are mis-aligned/out of position...something silly....it's always something silly....

The brake caliper mounting bolts were just a little too long... And apparently, in one of my more genius moments, I didn't put the lock washers back when I mounted them. So when I torqued the wheel lug nuts down, it was pushing the brake rotor into the caliper bolts and locking the wheel up hard.
Nice gouge marks in my new slotted, drilled rotors. But it's good news, as it's not the rear end or something else co$tly.
Didn't we have a rookie mistake thread going some time ago? This probably qualifies.
