Where is the diff leaking from? No it won't cause a wobble.
Look around for a shop that does suspension and frame work, someone can check it for you.

My 99 disco II (160k miles) has recently started having this problem as well. It seems to be mainly after hitting a bump so my first thought is shocks. I looked around under the truck and it looks like the bushings are cracked. I looked online for a bushing kit but found nothing for 99 and up IIs.I guess I have to buy each bushing seperatly? The wobble is only in the steering wheel. Any thoughts or suggestions on where to look first?

 

Drnknmnky13,

Read my sections regarding suspension and steering at www.eurotekapg.com under technical info.

There can be a combination of worn components causing the wobble. Steering dampner, tie-rod ends, and Panhard rod bushings are a few of these.

I had a wobble at 55mph, got the tires balanced, and it ran smoothly afterward. I had to replace two out of four tires because too much pressure warped them!

good luck mate!

 

My 96 Disco also has a pretty serious wobble around 50mph, it also wobbles when I hit a hole, the higher the speed the more sreious the wobble. I am going to be getting my tires aligned, but if any of you guys that are experiencing this same problem find another problem area to look at, please tell me so I don't have to get too dirty.
Thanks
Nikki
