I had a 99 WJ and I broke my Rear axle on it. A friend went to a junk yard and found me an axle he said was from a WJ just like mine n it was like $150.
After he installed it, I could tell my WJ was faster! Like it would take off from a stop really fast!!' so im thinking the gears were different.
My question is
1)- Which axles with a better gear ratio would just fit on my 92 YJ WITHOUT any modification. From what year/make/model vehicle. Just bolt on. I have a D35c (c=custom NOT "c" clip/4.10 gears).
2)- Would I have to change my front axle as well (D30) or not?
3)- Would it b an expensive job to do? My friend and I don't talk anymore and he did it all for "free". Don't ask haha
4)- When it comes to gear ratio, the smaller the number the better? I'm confused.
5)- Would regearing be a better option? How much does a job like that would cost? Curious.
I really appreciate it, thanks in advance.
2. Yes, front and rear gear ratios need to be the same. This is not negotiable.
3. It could be. Depends on what you buy, how much of it you can do yourself, etc., and what other stuff needs to be done in conjunction with the rear axle/front gears swap.
4. Define better. Higher number = more torque multiplication, less top end speed.
5. Depends on what you're aiming to do. I wouldn't put to nickles worth of "upgrades" into a Dana 35, though many folks do. Regearing one axle with OEM gears or high-end aftermarket will probably run you $400-450 in parts for the gears and master rebuild kit, and a couple hundred in labor to install.
