lift kit questions?

Hello everyone I have been looking at a 4" lift kit by rough country but cannot figure out why they say it won't work for all wheel drive. Can anyone explains this to me please

Here is the link

I don't think there is technically anything that would stop that other than that your front DS is probably a repezza-repezza and won't last long.

Look up CCOR here on the site for more onfo.. that is where I bought mine. Send them a PM.

Most kits will have something similar written into the fine print. The reason is that lifting puts your drive shafts at less than optimal angles. So they are 'warning' you to cover their own *** in case yours fails shortly after lifting.

It even says not for AWD on the 2" lift kits on Rock Auto. I don't think there are any near extreme angles on a 2" BB.

Yeah I didn't think there was any design issues that would cause it not to work on the awd models. Now just to figure out what vibration they are referring to also lol

Here you go. Your 99 most likely has the weak repezza unless it was replaced already

AWD means that there is torque on both your front and rear driveshafts at all times.
If you have a repezza or CV style front drive shaft your best bet is to replace it.
99 WJlimited chances are you have the repezza style driveshaft. Repezza's fail fast when their angle is changed. Regular U jointed Driveshafts will last longer.


Top is Repezza. Bottom is U joint / Double Cardon.

Yep. All good after replacement. Look on craigslist or a junkyard. Or you can get a new expensive one from tom woods carolina or iron rock. The pita factor depends on rust. Spray with pb blaster a few days before and you will be all good.

Junkyard is by far the cheapest. I have about $100 in mine and I rebuilt it myself in the garage with hand tools.

If you have a rezeppa, it's not as simple as just replacing the shaft with a double cardan one. You also have to replace the yokes at the diff and the tcase.

That can be a b*tch without a good puller tool

So this $500 kit is sounding over $1000 to me

You really don't want to lift your dub 4" for $500... A budget boost and good shocks along with a drive shaft would cost more than that. Be patient and do it right the first time. You will be happier with something functional instead of something you keep having to throw money at. How many miles are on the 99? Just lookin out dude.
