Starting to get some shatter in my limited slip rear end on 1979 Pontiac. Changed out gear oil with fresh and added this additive. Rear end operation on car now is back to smooth.

This is a must have for Corvette rear ends. My c3 sounded like it was going to fall out. Drained all I could and added the additive and filled with clean gear lube, did the figure 8's , like a new car, no more noise and jumping. Don't leave home without it.
