99 jimmy rear locking limited slip

my problem is when i come to stop and than make a left turn it seems that the rear is locking i pulled the cover and checked the gears all look ok any help would be helpful also i am looking for a diagram of the parts thank you

Make sure you re-fill the rear end with gear oil with the GL-5 rating. Make sure the tires are the same size all the way around.

I had a similar problem it ended up being the drivers side caliper locking up. I ended up replacing the brake dust shields and both rear calipers and now all is good.
