I want to upgrade my stock gears to 3:73. The motor has alittle more then 100k on it, just woundering if I would need to replace anything else in the rear end other then the ring and pinion?

If it has never been seviced, now would be a good time to o/h it.

 

It would be wise to buy the T-Lok rebuild kit with all new bushings, seals and so forth. It even includes the oil so just take it to a shop and have me toss it in. With 100k miles I am sure you got the 1 tire fire so youll have both tires spinning once again as well.

 

The rear end has been services when recommended, Both wheels still spin which is a good thing. Thanks guys
