UCF and caster:

Just FYI, if you're going to do the BJ's anyway....it might be worth it to spend some extra $$ and get the offset ball joints.

As with all things Jeep....YMMV.
So,

With no SYE and adjustable arms, you had front caster problems with the standard or no-lift UCF TT?? I thought the arms would adjust the pinion and keep everything close to stock. Hmmm. Is it something to do with the MM/BL and the TT? Does it lift the front output?

Excellent suggestion if so. Sorry for my nube-ness, but I hadn't even considered that. Can you (or anybody) explain why? I'll be delighted to put the adj. front caster BJ's in. Do I need upper and lower?

thanks for any input.

Sorry for the Hijack. Guess it's all good if we're doin the same thing.

you need a SYE for any TT and adjustable rear upper arms are needed too. a MML is a good idea to to at the same time. Brown Dog has nice MML for cheap with a great warrenty and its built in the USA.
BUY USA built when you can

Is the SYE absolutely necessary for UCF STD with:
3" lift
adj fr and rear arms
1.5 BL/1 MM

on an LJ.

i know yes on TJ.

I thought you could get by with UCF TT and BL/MM less than 3.5 " lift.

SYE has nothing to do with the front end of course.

For the record, it was the standard UCF TT.

Sure, the adj arms allow me to adjust the pinion up, but each degree up is a degree of castor gone. !!!

In my case, and the usual "all Jeeps are different" applies, I couldn't achieve both a good castor angle AND good pinion angle (notice I didn't say "correct pinion angle"....'cause I only got that close enough). The 2 degree upper BJ's did the trick. Lower BJ's are stock Moog.

I don't understand your question "Does it lift the front output?".....if you mean the TT...yes it does, as it lifts the entire transfer case, front and rear.

My LJ has the same setup that you propose above, except I have 4" lift.

My guess is that on level ground you wouldn't need an SYE....you'd likely be right on the edge of it working. However, with articulating the axle off road.....I think you could find yourself in a binding (read "breaking") situation.

Personally, I wouldn't try it without the SYE....but you could try it and see if it vibes.

You might also call UCF....they know their product and likely have seen your setup before. Take their advice would be my advice...and then take your chances if you decide against the SYE.

If your questioning the SYE I'd get it, for the extra $150-170 for the normal length SYE its better to do it while your building then rip it all apart and redo it later because you find out you have drive line vibes cause you were try'n to save a few bucks

Ok, Ok. I get the message.

I didin't think you could manage an SYE for that little money. Let me research the cost. I'm not arguing about $200. My labor alone to 'do it right the first time' is way more than 200.

Any suggestions as to the best/least expensive SYE for LJ? What do I need with an SYE besides the SYE kit?
again, thanks.

For the longer wheelbase LJ Unlimited & 3" suspension lift, you absolutely do not yet need a SYE & CV driveshaft. That is because the LJ has a much longer rear driveshaft when compared to the SWB TJ that starts needing a SYE/CV driveshaft at 3" & requires one at 4". The Unlimited's longer driveshaft angle doesn't steepen as quickly in reponse to a suspension lift as the TJ's shorter rear driveshaft does so it doesn't need a SYE/CV as soon as the SWB TJ does.

If you start doing things like a tummy tuck and/or a significantly taller suspension lift, then it's time to spend the $$$ for a SYE & CV driveshaft. But it's not needed now, save that $$$ or use it for other mods.

Well, I got off my butt and researched the forum. Wow. Some great info out there.

Basically, from what I've read from the other LJ owner/experts on here, the LJ would handle a 3" lift with 1 BL/MM and a std TT. Net of about 5". (Every Jeep is different, yes, I got that).

But, that would just make a very capable mall-crawler. Axle droop and flex would wear hard on the drive train and potentially drop the drive shaft and ruin the TC. I think I'll look at just doing the lift (and BJ's and steering) and then do the SYE/DC and TT at a second sitting. Besides, after all the reading, I'm thinking that I may want to outboard the rear shocks and move the upper spring perches once I'm ready to do the SYE/DC and crank the pinion up to point at the TC. That really is quite a long list of work--for me.

Less sticker shock that way too.

Thanks for the great advice--I should be able to run the 3" with no really issues and just leave the TC alone for a bit. the nice thing about the Savvy kit: you can easily adjust the arms without any major surgery.

cheers.

I did 4.5RE short arm with a AEV tummy tuck best idea, just upgraded to 35s, power is still there with the stock gears but im going to upgrade since driving up hills still kills my gas, i recomend checking 4x4groupbuy.com they have killer deals i got my SYE and CV from tom woods free with the RE kit i bout. saved me 600 on just those parts.

thats 21in of break over clearance without a body lift.

also first photo shows a 1in spacer just added to front to level it out

just catching up on this thread...the LJ came out nice there andrewf.

looks like: with the hardtop on and no-winch, you rake down a little in the back (a winch would fix that!). Is that right? any spacers?

BTW: this pic proves why I don't want to go any higher than 3" on 33's. Good lookin LJ>
