Adjustable Control Arms?

If install adjustable control arms for my 05 unlimited, can get away from using a cv driveshaft & slip yoke eliminator and remove my tcase drop. Would i also get a better ride aquality.

u can do that without the control arms. The SYE and the transfer case drop kit do the same thing.

eh - don't worry about it. When I get my RE 3.5 installed I'm getting adjustable uppers for the front and rear and may still need a t-case drop. which isn't really a bad thing.

u shouldnt get vibration if u just run the SYE and driveshaft without the transfer case drop. Like i said, if some weird reason u do, just buy a motor mount lift. its only 60 dollars. Its does the same thing as a t-case drop but at the other end.

The reason you would need adustable uppers when you do the SYE is because you need to point the rear pinion at the output shaft of your TCase.

JeepGuy, did you try your lift without the TCase drop at all? With your LJ you have less of a dshaft angle than anyone with a TJ will due to the extended wheelbase. You very well might find that you have no drive line vibes anyway.

Just knowing the extra inches of wheelbase an LJ has over a TJ combined with the lift you have I would bet that the vibes would be non-existent to very minimal without the TCase drop.

With your LJ you should not need a T-case drop with a 3" lift.

On my LJ, I have a 2" lift and a TT which is about 4.25" of drivetrain lift. I do not have a sye, and this was with stock control arms.

I still have all stock control arms, but looking to getting adjustable rear control arms so when I get my SYE, I can go with a belly up skid plate.

but he doesn't have the long wheelbase LJ like you. With your longer drive shaft I don't think you'll get vibes. Didn't get vibes in my XJ untill 4"

Well boss it's entirely up to you. From experience I don't think you are going to get vibes without it.

It would probably be easier just to do it yourself if you want to. It's just 3 bolts on each side. If you have or had access to a floor jack you could have the whole job done in 15 minutes. Pop the bolts off one side and have the jack under it to keep it stable. Remove the spacers and run the bolts back into the skid and frame. Repeat on the other side.

I agree with Jack, Just do it your self and save lots of time and some $$. It's a super simple project that just takes minutes!!

They are either 12 or 14 MM, I think 12 if it's newer than an 03, 1/2" if older. I would probably try to use the ones you have and just make sure they don't bottom out. And yeah that's all you have to do, remove 3 on one side, take out spacer(s), and put them back in, but don't tighten down, then take out the other side and remove spacer(s), then reinstall bolts and tighten them up, then tighten up first side and that's it!!

How is it a good thing? What sense is there in paying money for parts, spending time to install them and then negating the most important benefit to your breakover angle by dropping the belly skid?

Do it at home: 30-45min job, Tiny can help ya if needed .... take it for a test drive, and if the vibes are there, put the spacers back in.

For me or for JeepGuy? For me - I really wont be able to wheel my junk as offten as I like, so the t-case drop won't bother me untill I drop a bit more coin on my rig with a D44 rear and SYE kit... then I'll remove the t-case drop.
