did my lift

This weekend I set out on doing my lift 98 xj...primarly cosmetic reasons. Planning for 2.5 to 3" lift.

96 CG from v8 - front springs
One inch spacers

97 s10 leafs
xj main, s10 main, xj 1st, s10 3rd, xj 2nd xj 3rd (in order)....so I left out
2nd leaf from the s10, ....seemed worked out nice because lenghts all fall shorter has you follow the leafs down.(ones not longer, or same lenght as the leaf below it)

ride heights
front 20"
rear 21" (rear is 4" lift!)

I don't mind the look...back sitting little higher than front and Im thinking it will sit over time, but Im getting vibs in rear on 0-5mph accerlation(don't really notice it accerlating from higher speeds), and can clearly see pinon angles are not pretty.

Should I add 1 degree shims? (whatever autozone sells, I believe they are 1 degree) or should I remove s10 3rd, and replace with s10 second(longer leaf), and am I going to see any problems adding JK shocks with 4" lift?

SIDE NOTES: really enjoyed doing this lift....good research made come together easy. snapped a shock bolt. tried extending stock shocks with union and thread(typical automotive stores, or lowes doesn't carry m10-1.5 union grrrr). Jacking opposite side of axel really helped remove/replace springs, time....only me, 2 monster energy's - 4 hours friday night, 10 hours saturday (minus lunch smoke breaks, and 1 hour trip to lowes to search for unions).......I still have shocks/sway bars to install (guessing 4 hours not including fab work)......hardest part was installing heavy wheels/tires. With 3-4 lift, 31" tires still rub! (they do have alot of offset, stick out inch past fenders)

Also wanted to give the next guy a closer price cost of a diy build....

JK shocks...yet to be bought...from autozone $160, craigslist specials $50-100 used 0 miles to 25k. Jeep dealership hasn't been much help, first time I ask for old parts they said they just trashed them all, 2 months later check back each week, yet to have any freebys for me

springs.....$20 each - pull-a-part
leafs.....$32 each pull-a-part
coil spacer - $25 1" ebay
misc bolts (sway bar ext, leaf through bolt) $15
wranger brake line - $15
u-bolts - online 4x4 shop $25 shipped

I would try and get the rear down a smidge. I cant tell you which one to replace with another, its gonna take some trial and error. If that doesnt work the shim or a tcase drop would help. At this amount of lift your gonna get vibes.

Transfer case drop, or MEASURE your angles BEFORE installing shims.
Absent a SYE / Dbl Cardan driveshaft, your pinion angle should be parallel with the transfer case angle.
The Tom Woods web page has a write up on this.

my friend has the same jeep and he just put a 3.5" rubicon express lift on it. He does not have a transfer case drop but he is ordering one because he is getting really bad vibrations at all speeds and especially 30-40. He hasnt really gone much faster since he just put the lift on and lives in the city, so he hasnt taken it out on the highway yet. He heard that the transfer case drop is bad on the engine mounts. Is that true? I have an 07 Chevrolet Colorado and after I lifted my truck and did a tcase drop it didnt affect the engine mounts. So I was just wondering with these XJ's, will the tcase drop be bad on the engine mounts or are there any downsides to doing the tcase drop?

From what I have heard, T drop is a cheap mans way to fix the problem, kinda like putting bubble gum in a crack on a dam. Seems like it would hurt the mounts...as your angling the motor and twisting the mounts.
