There is still a very slight wobble at high speeds on my recently purchased 2003 Disco. It is very slight, but still annoying.

It was there when I had the original front prop shaft. It is still there after doing the following this month:

* New 75W90 gear fluid on diff (transfer case will be done this weekend)
* New transmission oil and filter
* New front and rear shocks
* New wheel balance
* New front prop shaft with greasable joints

I am wondering if it would help if I replaced the rubber coupler in the rear prop shaft? Any ideas would be greatly appreciated!

Thanks!

 

First use 85/140 instead of the lighter gear oil.
How many miles on your truck, has the drive shaft been rebuilt or replaced and have you even looked at the rotoflex to determine if it is failing, if it is bad it bill have large cracks between the 6 bolts.
Then of course, there ia also the possibility of warn bushing, tie rod ends or out of balance tires.
