ZR-1 Net Registry Forums - View Single Post - Heavy popping in left rear (U's? Half shafts?)

Schrade · 06-15-2013

I got a new sound in the drivetrain - a heavy 'clunking' in the left rear, as I roll up and down the driveway.

The speed shop that did the auto conversion had the wheels in the air, testing the speedo link. I said, "Isn't that bad for the U-joints?"

They said no. They spun it up to 50 - 55 on the speedo.

Car only has 32k on it here.

Thoughts? Opinions?
