3rd rear end in 2 years

[Hobbs95]

Back in May replaced entire differential - gears, axles, bearings and whatnot you name it was done. I had it done at the chevy dealership in town. I drove it less then a tank of gas and it locked up on me would pop and slip when I turned left and louder when I turned right. I took it back and they replaced the carrier and put it back together… its been about 1000 miles since that fix and its starting to lock up again not as bad but its definitely not a normal sound it sounds like the oil needs to be changed but I am not touching it until I take it back to them on Monday.

Any input would be appreciated

I’ll post what I hear on Monday from the dealership

They may have forgotten the limited slip additive.

i asked them that the first time in may and the technician seemed to believe he put it in and the second time they were confident the put the additive...
