Tom Woods. Perfection.
you don't need adjustable control arms per sť. If you do need anything, you will need lowers for the front and uppers for the rear. See next statement below for qualification.
On the rear absolutely yes — on the front, case by case basis. I have a 4-6" lift and do not require adjustable arms on my front shaft. They told me I needed them, I bought them, installed the shaft, and sent the arms back. No vibrations, no steering issues, nothing. To each his own.
FML Has anyone ever put a list together of all of this information...such as what those settings are with different lift heights etc. or is that what the local 4X4 store is for?
I took a leap of faith and after A LOT of reading, installed the front myself with no issues. Didn't need to adjust the pinion angle or anything, this is on a huge lift too. The front is less crucial, some people need it, some don't I guess. When I have a few hundred extra to burn and don't have anything else to upgrade on the Jeep, I'll get them eventually. The install is really quite simple, I wish I did a detailed write up when I did it... sparse recap below.
1) Remove all skid plates/armor in the way of the front driveline to make it easier.
2) Unbolt old shaft, lots of bolts, no big deal. bang the shaft off with a mallet once all the bolts are off as it will be seized in place.
3) Remove the existing pinion nuts with a 1-1/8" and 1-1/4" socket on the transfer case and differential.
4) Use a gear puller remove the flanges from the transfer case and differential. Rent one from your local auto store for free basically.
5) Install new Tom Woods flanges, silicone the insides of them before putting them on to make them oil tight.
6) Install new pinion nuts with red locklite and torque to 160lbs. Differential end is easy cause it's locked in place. Transfer case end is a ***** cause it spins freely, I used a huge monkey wrench to keep the flange from spinning while I somehow managed to get it torqued to spec.
7) Bolt both ends of the new Tom Woods shaft in using red locktite on all bolts and torque to spec, I just did them really tight without stressing them.
8) Take it for a test drive and see how she does... Since the front shaft is always spinning whether you're in 2WD r 4WD you'll know right away if things are wonkey or not. Take it slow and see how it does. If it's smooth as can be, engage 4WD and test it out as well.
TIP: I originally did not locktite the new shaft bolts into place at first because if it jacked my ride up, I'd be able to easily take them off and remove the shaft (so I could at least drive around) to later have the adjustable arms installed, then reinstall the shaft.
