Damn that's crazy, I totally forgot the C5 doesn't have a drivetrain entirely rigid and attached to itself. From engine to diff. One solid piece. Darn, silly me
shoot, and here I thought 3 measly little mounts held up the entire drivetrain!! 2 of them being oil filled from the factory! I guess we all make mistakes *shrug*
thanks for clarifying that the engine mounts have no direct link to the differential! Gosh for a second there I was gonna suggest checking to make sure the passenger motor mount wasn't broken, but hey- that only matters on those silly cars that don't have torque tubes

OK OK I realize that you may be right about the rigid drive train, I've never had one before. I'll be sure to check the mounts. BUT I've had race cars break a motor mount and it's pretty obvious when that happens. A good motto is "keep a open mind", I'll check the mount. Thank you

Yeah…that idea about the passenger motor mount seemed worth investigating. A broken mount might be more or less apparent depending on which side. Looking forward to your findings. 👍

OK, I had a chance to check motor mounts yesterday. They looked good, put the car on jack stands and used a floor jack with a piece of 2x4 to push up on the motor (man, wish I had a lift). It was firm and picked the car up off the jack stands. One think I forgot to mention was when I bought the car the slave cylinder ruptured right away from sitting for 19 years in storage. Had a local dealer put a new one in, You know the work involved, I wonder if they did anything wrong on the reassembly.

Not really. I have my original C5 control arms and bushings in a C6ZR1 cradle with the C6Z diff. I had bad wheel hop previously with the same control arms and bushings; after the swap, the same control arms and bushing, no hop. Worn bushings certainly could be an issue but my in experience, it's beyond the bushings and in the actual driveline configuration. Probably 85% the driveline design possibly 15% suspension and tire.

Tires may be an issue, when I got the vette the original Goodyears were hard as a rock I guess after being in storage for so long. All they did was spin and never softened up and grabbed any traction. After I put the new rubber on I noticed the hop. Bushing all are tight and no sign of rotting. I did replace the swayer bushings. I thought of trying a C6Z sway bar.
