OK, this is on my 96 disco.

I finished installing 2 inch lift, drove it, no squeek, all good.

Then, Ireplaced gearbox mount, and greases Ujoints and everything that I see.
Now, when I drive, there is a squeak squeak squeak squeak squeak ... and it goes faster with speed.
IDK if it is the ujoint or what. I greased all the ujoints and anythign that needs grease. I guess I should had not done that, and let it be. It's one of those dont mess with it if it is not broken deal. LOL. Damn it. squeak squeak squeak squeak squeak squeak squeak ....
any idea? I have both rear tire off the ground and let it run, no squeek. IDK. I grab the rear shaft and wiggle it, no play. It is coming from below the rover, if i stick my head out, i hear it right under / behind the middle of the rover.
Suggestions, ideas.....

 

im betting on a u joint.....un hook one end of the driveshaft and see if the joints all move freely....with the lift they are now at a slightly different angle
