I found an add in the local paper for a front and rear set of used, aftermarket 4:10 ring & pinions for a mid 80's Jeep CJ. I will try calling tonight but not sure if it is worth the effort. Am I playing with fire buying used gear sets? If not, what questions should I ask? What does a poorly abused set look like minus broken teeth?

I have a friend that is a master mechanic and he has gearing installation experience so I am hoping the used set is worth it becouse I am planning on running 33"'s and they cost plenty enough already!


85'CJ, stock for now! It's a Jeep thing ...my wife doesn't understand.

As long as the front didn't come out of a quadratrac, I would think the fronts wouldn't be much of a gamble. The rear on the other hand, might be like new or worn. I'm not sure how to tell the difference though, hopefully someone here knows.

What would be the problem with Q-trac gears? Just curious.

What's you gear ratio now? The carrier break on the D30 front axle is 2.73 to 3.54 and 3.73 to 5.38. So if you have 3.54 and down gears now, you'll need a new carrier for the front. The rear should be OK unless you're running 2.73's, and then you'll need a new carrier for the rear as well.

GaryL,

the Qtrack front axle has a load at any given road condition= the gears have more wear, than a front axle gearset that has lockuout hubs.

its very probably to find front axle gears from an older part time truck with 100 or less miles on them, since hte hubs are usually unlocked
