Lifting a XJ

[Goose]

My boss here wants to lift his XJ... I have a couple questions... with say 3" of lift.. you dont need to do the Slip yoke eliminator or drop the t-case do ya?? (I am going to end up doing this lift... and I really don't want to be unemployed.)Black mountain kits from collins bros ok??

You can never tell on an XJ. You should be safe, but I've heard of people with u-joint vibes with as little a 2" of lift. I have a friend with 5" of lift on an Xj w/o a slip eliminator. Make sure you include the t-case drop in case of vibes.

One trick is to use YJ (Wrangler) driveshaft yokes, which have more clearance than the XJ. Check the yoke clearances at full droop even with 3", you may need to clearance a bit with a die grinder.

The SYE isn't bad, I did it in my shop in under 4 hours to a YJ (NP231). Just remember to match the shift yoke shaft to the detent. Mine was too long after the conversion so I had to cut off almost an inch of the shaft, and it's still hard to shift into 4WD 'cause it hits th4e cap.

Like Bob said, for some reason all XJ's are different. I rarely heard of anyone needing an SYE due to vibes under 4"s but have heard it happen.

I have 4.5" in my XJ with a rustys off road 1" drop cross member and have no vibes at all. its a 4.0 with automatic set up.

Most likely if there are vibes, you will be able to get away with just a t-case drop. As far as brands, I have installed a bunch of rustys offroad lifts all worked really well. Don't think you could beat it for the price. I have a Rubicon express lift in my XJ now and love it but it is more pricey.

Those would be my top 2 recommendations though

Thanks guys..I am really looking forward to this (so I can find out how it will work out on mine..)

Daughters YJ still has a vibe issue about 50 MPH even AFTER the SYE, new Tom Woods CV shaft, a 1" tranny drop (engine and tranny both rebuilt) and new U-joints

Sure its in the rear shaft? Drive it in front wheel drive only, remove the rear shaft completely and see if you still have the vibes?

if so, just stretch the wheelbase so you could get a longer shaft in the Jeep

Well after chasing the driveline vibes in the J-10 for so long.. I found out the stub on the new retubed drive shaft was about 1.5 degrees out of true..

Don't even have the front shaft in right now!!!

And the stretch deal ... been there done that remember this?



An 85 Scrambler stretched 18" ??? Not one of my better ideas ....

Do you have any more pictures of the stretched scrambler? That thing is sweet!
