I get a severe juddering, more so when it's a faster pull away. Like the wheels are slipping, I have a LSD in the rear, does this do it, or clutch? Help!

Try pulling towards you or use your left hand 

       sorry .....I'll go away now.       

[greggmo]

if the jeep is stock with no lift or mods then the clutch packs in the lsd are most likley fooked. or the axle is shifting around cos all the bushings are toast.

[isle of man]

Have you the correct oil with additive in the axle?

[Mudrat]

4inch lift, which additive to add and where can I get it easily? Cheers

[chrisjones]

Additive can be obtained from your local Jeep stealership (and for once at reasonable cost).

If you have 4" lift it could be vibration caused by the UJs binding because of the prop angles, sometimes a 4" lift will cause it but it seems to be dependent on the truck and brand of lift kit used.

However; I'd start with trying a shot of diff additive and see if that helps.

Lots of things to check - control arm bushings, diff oil and additive change would be good, rear prop angles and UJ condition.

Tricky to diagnose unless something's obviosuly loose or fooked unfortunately.
