And he wondered why the t-case exploded. FYI I am running 3.2-3.4 of caster on my JK with a TeraFlex 4" LA kit.Also you need to maintain your aftermarket driveshafts.

I am just trying to understand something here....Why can't the front driveshaft just be a single u-joint or single cardan coming out of the transfercase? Since you can't point the diff up because you would give up necessary castor. I have seen diagrams that show a double cardan out of the transmission going to the pinion and the pinion was on the same angle as the driveshaft. On the single ujoint the pinion was level with or along the same centerline as the output shaft of the transmission. This would work for the front since the front end is designed almost like that right????

This has the pics you are referring to and some info on the angles for both types of shafts. Look through the rest of the site for more great info.

so if you were to go with a 4 inch lift, like this one http://www.roughcountry.com/jeep_jk_4flex.html, you would have to get a new driveshaft?

my head is spinning
if you have 2-door, yes, you will need to get a new rear shaft sooner than later and, if you have an automatic, you will need to get a new front shaft. if you have a 4-door, you can make your rear shaft last for a while longer and the same is true up front if you have a 6-speed
Ok, so I should look at investing in new dirveshafts sometime in the near future after I get my 3" or 4" inch lift (either FT or TF)? again I have a 6sp, 4:10 ratio, 07 sahara.

My regards are to the starter of this thread. Didn't mean to hijack but it happened.

yes, sometime in the future. being that you have an unlimited and a 6-speed, i'd be willing to bet that you can make your factory shafts last for a while.

Too many variables to answer that, just make a habit of crawling underneath and checking both driveshafts.
With a bit over 3" on my unlimited, I lost the front shaft at the tcase with just 4-5k of on-road driving. Many people are still on stock shafts with higher lifts and 20-30k. Just depends.
