front diff problems
 

hey i have a 1/10 scale nitro pirate 10 buggy and i had to replace 1 half of the box that holds the front diff and after i did when you spin the drive shaft one wheel spins while the other has trouble and if you spin the wheels backwards they lock up and when the car is running and you rev it the whole front starts shacking realy badly. does any one know whats wrong?

Thats what happened to me!!Take out the diffs and probably a ballbearing is gone ,or something else.If youve tooken them out already and its now locking then the main diff gear is the wrong way around change it,i think...thats what happned to me try it,i may be wrong since im not exactly really expreienced.
