Transfer case drop removal.

I want to remove the 2" t/c drop on my YJ. How much is involved? Is it simply just removing the spacers or is there more to it? Do I have to change the pinion angles or get a longer drive shaft? Here are some pics.

With 4" of lift you need the TC drop to fix your drive line angle.

If you want to get rid of the drop you will have to do a few things, like; motor mount lift with maybe some shims, or a SYE with all the extras that go with it.

The best route, in my opinion since you already have 33" tires, is start saving for an upgrade to your rear axle and do the SYE. The Ford 8.8 is the most popular upgrade.

I have the SYE. Wasn't aware about all the motor mount stuff. Might not be worth it. I am looking for the ford rear but it will be a while. Have to either re-gear it or get the front done at the same time. I currently have 4:56 gears.

Now that the pics are available I see you do have a SYE.

I would remove the TC drop and see what your drive shaft angle is. If it needs adjusted I would go with shims on your rear axle to fix the angle. You could grind off your spring perches and reweld them to fix the angle, but shims will do.

Don't worry about a motor mount lift, but... it could be used instead of the rear shims IF it would fix your angle.

So, until you remove your TC drop, you won't really know what needs done. As long as your TC skid bolts come out with no issues, it's a pretty straight forward job. Put a jack under the skid, apply some pressure, remove the bolts, remove the drop, jack up the skid, position the skid and reinstall the bolts, done.

EDIT: Curiosity question - why do you have a TC drop AND a SYE?

I wonder too, why the TC drop and the SYE together? Probably just something that happened over time.

Your driveline angle looks great, although the exposed spline scares me. You really need a boot to keep that thing clean or it is going to destroy itself by binding up, which might take out your TC.

You don't have a 2" TC drop. It looks like about the standard 1", and all you have to do is remove the spacers and use shorter bolts. Looks to me like that will improve your driveline angle even more.

You've got about a 2" body lift.

That body lift is quite scary. I have seen worse but not by much.

From the pics your pinion angle looks high. Removing the tc drop would help. However you don't really know until you put an angle finder on that bad boy. They are cheap and can be found at any box store like Lowe's etc.

Photo angles can be deceiving, but that looks set up proper for a sye. The rear pinion want to be down just slightly. If you raise the skid, you will likely need to shim the rear spring perches or move them. You really need an angle finder.

This is how I got it. All work was done by a PO. The jeep is a bastard. It has 89 axles, 94 -95 transmission, shackle lift, body lift (as you can tell) and I believe spring lift. It had 35's on it when I bought it. I do some trail riding and would like more clearance (cyprus stumps and all) I was told it had a 2" body lift and 4" spring lift. This is my first jeep and I am learning. Believe it or not it runs down the road pretty well.

Is it just because it's a 2" lift?

Most people around here will recommend a max 1" body lift. And then it's best to buy a 1" body lift kit from Daystar or other reputable company. Stacking isolators like the PO did just doesn't look right. There are only 11 bolts holding the tub to the frame, and the higher you go, the more stress on those 11 bolts.

I'd take off the bottom isolator, which I think will leave you with a 1" body lift.

35s take a little work to fit onto YJs - especially in the rear fenderwells. I'd recommend TJ flares and some sheetmetal cutting to gain back the tire clearance that you want. Or tube fenders, if you have the budget. Or high line your hood for more front clearance.
