rear end question

kinda new to this but is there a pin in the rear gears that makes it poss trac got a broncol but it seems to have limited slip, i was told these pins break causing that

No they use clutches

The pin is in both single and limited slip axles.It holds the spider gears in. What breaks is the hardened bolt that holds the pin in. You usually have to center drill it and use a EZ out if the bolt head snaps off. Be careful when you first start to turn it with a wrench,if it breaks it is a BIAAATCH!

will the truck still move if it breaks? it acts like it has lim slip ,,,,,it moves fine now ,, but its just a toy and i want it to get through mud good as it can,,, just hoping to find out what i can do
