Xj unstable on road after lifting

[Monstermk2]

Put in some new bits into the missus car bog stock 01 petrol Xj with the idea of 4" lift and 33's ,

Parts installed

Brand new gear installed

rubicon express 4" long travel shocks all round 'Double black off road supplied'

Matching rubicon steering stabiliser

Rubicon adjustable johnny jointed
Front upper control arms ,

Rubicon lower adjustable rubber bushed lca's

Rubicon extended braided brake lines



Second hand gear fitted

2.5" pro Comp rear Spring pack , re bushed and fitted with a 2" add a leaf ,

2.5" pro Comp front coil springs with 1.2 inch Spring spacers

Adjustable sway bar disconnects that go upto 6" lift 'supposedly'

Adjustable track bar ,


Car had front end alighment done after
Gear was fitted ,

Car has horrible vibrations in rear , which I'm guessing is tail shaft angles ,

Do have a new transfer case with a slip yoke and an hd double cardnl shaft to go with it , that's getting put in shortly ,

Do I need to space transfer crossmember ? Or will the Double cardian shaft do the trick,




Front suspension doesn't seem right either , going to go over it again, in the morning , but it feels 'loose' and rattlely ,


Is there anything else Ive forgotten and should be put in the car to suit that amount
Of lift , ? I thought I had most bits covered , but now arnt so sure ,

And before people ask , yes upper control arm bushes in diff and new nolathane , and the front diff and brand new ball
Joints, bearings , cv's etc

Ask the wheel aligner did he do the caster angle, my experience is they don't, just a quick check of your toe angle, she'll be right, that'll be $80/$100 thank's, move your vehicle please I've got someone else to rip off. Buy your self a magnetic angle finder (Bunnings) or digital one off ebay & read Gojeep's site & do it yourself. Doing it your self will save you enough to buy 2 or 3 angle finders the first time you do it. Read up a bit before you ask him questions, you'll probably be amazed by how much he doesn't know. Sorry mate, got the wife to take her car in for new tyres I'd arranged, told them no alignment because tyre wear was perfect. When I got home she said she had to pay extra $180 for a full wheel alignment or they wouldn't let the car be driven on the road. Had a quick look under car, nothing had even been undone, still covered in mud. A bit cranky when I got to the shop, things turned to shit quickly, but I left with $300 cash back. Do it yourself, let the thieves starve. Regards oldon.

did you lenght en the lca there is a chart on here some where

As oldon and murray both mentioned check the lengths of the control arms are correct for the lift AND the caster is correct, it's easy to check, I use my angle finder on it and it's easy to set, I also found depsite the specs stating 0 toe mine runs much more smoothly with a little toe added...

You need to set the diff to 5' on the face of the center. My tj was all over the place with 10' now drives good. You steering will also be turning in from the lift.

Without a DC shaft, even with crossmember spacers some XJ's will vibrate from experience. The only surefire way to ensure it no happening is with a DC Shaft.

The 2nd hand swaybar links, what brand are they. They can sometimes cause rattling issues also.

Could be the nolathane bushes increasing vibes as well.
