I just had my motor replaced and I was driving this weekend and noticed some noise and vibration at highway speed and need some suggestions...

At 70mph I'm getting a mild vibration and low frequency noise in the cabin of the Disco. It feels as if the vibration is coming from the center of the truck. It starts at 70mph and gets worse the faster I go, I got up to 75mph and didn't dare risk it to go faster. When I sold down below 70mph the noise and vibration seem to disappear, or possibly just become not noticeable to me. The sound/vibration reminds me of possibly the front or rear axle being driven bone dry with no gear oil...

My 03 Disco just turned 67k miles. I previously had a 02 Disco that broke a front drive shaft and I thought this might be the case with my 03...

Any Suggestions?

P.S. I did stop at a local oil change place to make sure front axle, transfer case, tranny, and rear end had appropriate levels of fluids....

 

If it wasn't happening before the motor swap, I would take it back to your mechanic and have him recheck everything.

 

It was not happening prior to motor swap...any idea what could be the cause?
