Re: Rebuild Differential?
Put the rear up on jack stands, put the trans in neutral, put a mark on one of the tires. Mark one of the ujoint bolts, then spin the tire one full revolution and count the number of times the Ujoint bolt goes by. If it turns 3 3/4 times then you have 3.73 gears, if its right around 4 times, its 4.10, if its 4 1/2 then you have 4.56.. just make sure both wheels are off the ground and turning. if they turn the same direction all the time, then its a posi/locking/limited slip diff.
