hello all
Its been a while since I have posted, I am running a 98 tj with 3 in sus and 2 inch body lift on 33's and still have the stock slip yoke and control arms, I have beaten the heck out of the stock tranny skid plate ans was thinking of making my own. Money is tight so.. I was thinking of making it by using some 1/4 plate that I have and dropping it down 1 1/4 inch down from the frame, In hopes to limit drive line vibs also plan on getting 1 inch raised motor mounts and adj upper control arms... penny for anyones thoughts?
Cheers

Well, everybody's got their own opinions on dropping t-cases...but I think it's a bad idea for a number of reasons: (1) You giving up some central ground clearance that you gained by installing the lift so you could run larger than OEM tires; (2) Any reduction in rear driveshaft angle that you gain by lowering the t-case you compensate for by increasing the front drifeshaft angle; (2) You alter the static oiling characteristics of the engine. While engines certainly function when tilted either up or down (as when ascending or descending a hill), they are designed to have certain oiling characteristics, including gravity feeding of certain oil galleys, when the engine/vehicle is in a steady-state condition.

If I understand your post correctly, you intend to not only lower your t-case by 1.25 inches, you also intend to raise your engine mounts by 1.0 inches. That will certainly further increase the "tilt" that t-case lowering normally accomplished, thus aggravating the above problems.

I believe a far more functional and reliable solution to rear driveline vibration caused by suspension lift is to install a CV joint on the front of the rear driveshaft.

actually, the stock skid plate sits down about 4 inches below the frame rails, making the belly up would raise the T-case and tranny UP 3 inches, Ie if I did a flat plate similar to the one posted on 4X4wire threads I would make a very very steep drive line vib, therefore I was looking to build something like 33 Engineering Hi-Clearance Skid Plate. my concern was the need for slipe yoke elim and CV shaft,, I was trying to avoid the expense by going with a raised motor mount and upper adj control arms
sorry if my other post was not clear

I'm still not sure what you're build will look like, but if you're keeping close to the stock driveline angles there is no reason the stock slip yoke wouldn't work. It's main problem is that it's a weak link in the drive train and if it goes you have to stuff rags in the t-case to keep your fluids in.
