Default Re: Heavy popping in left rear (U's? Half shafts?)

Good chance it was the loose axle nuts. I've had a 91 C4, a 95 C4, and a 2008 vette and they all had a similar axle spline noises.

Don't have much of a clue on it there Bob; I cannot replicate, coasting, accelerating - reverse, turned right or left, forward, turned right or left.

Hub nut was tight, hub is tight, shaft is tight.

Only thing left was small Oak tree debris in the driveway, crunching under F1's @ 48psi

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?
The u-joint in the Ear of the Half shaft on the spindle is sloppy. when you accelerate you hear it moving.
