Well, the Corvette has had some nagging issues since I bought it in 2017 and I figure it’s time to load up the credit card with replacement part purchases.
The Vette has a nasty click and excess play in the differential. Along with that, she’s got a bad tie rod end which makes the rear wander all over the place. The car has some ~57,000 miles of on the clock and it’s time for some love. Although the car has been “kept” well since 2001, I can tell most of the common maintenance items have largely been ignored. Of course, I’m sure it doesn’t help that this is a northern based Corvette and it just sits all winter long, rotting away in its own fluids.
Anyways, I’ve gone full HAM and grabbed a lightly used C5 Z06 differential off of eBay and a new replacement axle for “just in case” (both not pictured). Along with that, I bought a new tie rod end and a new clutch w/slave cylinder for kicks ‘n giggles. I figured since the whole torque tube and trans/diff with subframe have to be dropped, I might as well get the clutch changed too.
The downside (although the intent was good) to owning a C5 or newer Vette is the torque tube and rear mounted trans with differential. This means I can’t really work on the drivetrain myself without a lift. Once I pay down some of the debt I’ve acquired, the plan is to find a shop, get this stuff replaced and have a whole load of maintenance items completed at the same time. (coolant change, brake fluid change, clutch fluid change, trans fluid change , diff fill, etc.).
My goal is to have it all buttoned up by the end of July. Once she’s good to go, the next plan is to drive from Minnesota to Wisconsin to watch the IMSA race at Road America.
Cool story, bro.

This pay a shop with a lift plan isn’t a bad idea. While it’s not technically impossible to drop the rear subframe and torque tube without a lift, it isn’t really a DIY job. My mechanical mentor turned wrenches as a vette specialist shop for awhile. A C5 clutch replacement was something on the order of 19 hours of labor at book rate.

I’m having the same thing done to my C5Z, but instead of getting a stock diff, RPM transmissions is rebuilding mine with beifier gears and new bearings, clutches and seals. Norris motorsports in Indy will do the actual removal of the diff tho. Its quoted to be $1800 for the diff rebuild and $600 for labor. I plan to autox my Z so it will see a lot of hard launches and 1-2 shifts, I’m thinking it would be better with the rebuilt.
Ping me if you need any details.
Also, I plan to drive to Road America to watch the Z’s brothers race :)

I’ve dismounted the Mini’s subframe and can confirm it was a PITA to align 4 bolts that hold it in place. I can’t imaging how I would align the 6 bolts for the Vette if I remove the subframe completely. Better leave it to the pros...
