I just bought the Tera Flex Extreme Short SYE Kit Combo With TW Drive shaft from 4X4 GroupBuy.com for my 06 TJ with 4 inches of lift.

How difficult is it to install an SYE? Anything I should watch out for?

Thanks for your help.

its not bad. i can have the tcase out, torn down, SYE installed, put together, and back in the jeep in about 4 hours...

just follow the instructions step by step and have a big clean are to work on / lay out parts.

I run that same SYE and personally I don't like to take the TCase out of the jeep. I can have one torn down and back together in about an hour and a half or so. For your first one it might be a little easier to do out of the vehicle.

Best suggestion is patience and a good set of snap ring pliers.

Yep, leave the front-half of the t-case firmly bolted to the transmission which will speed and make the job much easier. On the snap-ring pliers thing, it's not so much their quality as it is how WIDELY they will open. Most snap-ring pliers do not open widely enough, I finally found a set that did on a Snap-On tool truck. None of my local stores carried anything that opened widely enough.

Do you have a transfer case lowering kit installed with your Teraflex SYE? Do you have any viberations?

Once you install a SYE and longer CV driveshaft, there's no need to keep the t-case lowering kit installed. It would & should be removed.

on the same subject..... I was wondering If I could run a SYE kit also? I have a 2003 TJ with a 2" BB. I know in the future U wull be going higher but it will be ....well in the future. IF I did this would I have to buy a longer drive shaft after the lift was installed? Just looking at what would be the best economically. (sp?) thanks

You'll need a longer driveshaft after installing the taller lift so wait until you install that lift before installing the SYE and new longer CV driveshaft. It'll cost less doing it that way than buying it now and then paying extra to have the DS lengthened once the taller lift is installed.

To add to Jerry's response for you. No I do not have a T-Case lowering pucks on my skid. Never did. Lifted my jeep from stock to 6" and did the SYE at the same time. The Tera SYE lets me have the longest dshaft possible with out extending my wheelbase.
