differential oil on 07 taco 4d 4wd

I replaced the differential lsd oil on my truck. Because the rear end felt like it was dragin when doing a tight turn. I replaced and added the proper amount of additive and the differential oil sold at The toy parts center. The problem got worse. The rear end felt like if the hand brake was on or one of the brake shoes was stuck. Raised both rear wheels and they both moved forward when in neutral, like if the truck had full time posi traction. Took it to the dealer ship and they suggested to add two more of the lsd additive. so far it seems to have solved the problem. So keep in mind 2or 3 additive per differential oil change.

 

I always used to use 2 tubes of the additive when I had an LSD

As I outlined in the above link, I used ONE 4oz. tube.

I have not had a single issue, with 8k miles on the new differential fluid.
