i have 373 gears and when i do a burn out and it starts kickin sideways one tire will stop spinnin why is that

 

you may need a posi rebuid kit?..it's normal to go sideways soon as the right rear tire will get wieght transfered to it first.

 

i know its normal to slid side ways but 1 tire stops spinnin when it goes sideways

 

how many miles on car..my quess is alot...just pick up a rebuild kit there like 50 bucks..but here is a lil trick...pick out the best 1 -2 discs for your old disc pak and put it in with the new ones do not put them together put them with several of the new ones..this will really tighten up your posi unit.. this will help out a ton
