Here is the deal, im getting ready to order a Woods rear DS and im wondering if I need rear upper arms to get the right angles? Or can I take measurements and just put it on and be good to go? Im running a TF 3" kit with front lower arms only.

 

X2 on what planman said. Your pinion needs to be aligned with the tcase, sometimes a degree or two lower to eliminate vibes. The only way to get it in that sweet spot is adj arms.

 

How long will the rear shaft make it? I drove it about 200 miles so far, been spraying lube in there. Can I take that boot off and grease it up real good? Im wanting to get a few weeks out of it before I switch shafts.

 

You have a 4dr, correct? Your stock rear ds will last a long time(thousands of miles) unless you bash it into something. It's not at the severe angle that a 2dr is. I have 60,000m on my stock rear shaft. Only off-road once every month or so though. If you do alot of rocks, it's a good idea to go ahead and replace it. Easier to fix on the trail. The front ds on a four door usually needs replacing first. I'd look at that first.

 

With the torn boot? Can I cut it off and lube it up?

 

Which boot is torn? The slip joint( in the middle) or the boot on the rezeppa joint at the end of the shaft?

 

It is the one in the middle...slip joint.....

 

You'll be fine for quite awhile. Or unless you go muddin and start getting alot of grint and stuff in there.
