1999 GMC Sierra 1500 Weird problem Please help!!

[Azv]

So Here's the issue. If the back tire's spin "burnout" even slightly like if say it was wet out and I leave from a dead stop. 

My truck 100% of the time will pull really hard to the right afterwards and one of the two rear tires will lock up and release over and over then randomly the truck will go back to being just fine.

I can hit big bumps, drive on the highway, do anything and its fine. I've checked the diff and put new fluid in. leafsprings are fine i can easly turn the tires by hand. no noises either.

any clues?? also when the truck pulls right its a way harder pull then just a draging tire.

Oh and its 2wd

This very issue was posted by another new member to the site about a week ago. He claimed missing bolts in the front suspension.  I guess follow his lead since it seems both of you experience it with random bumps, and "Burnouts"

locking diff or open? any noise from the differential? possibly bad spider gears. pull the cover and take a look. have you checked to see if theres oil in the diff?
