Any ideas of what might be happening? 2009 Range Rover Sport Automatic Diesel.

When I get on the road, everything is fine, but as soon as I get up to about 48mph, it feels like I'm driving on rumble strips. The first time it happened, I pulled over because I thought I had a flat tire... The rumble continues when I slow down, but after a few minutes, it goes away completely. Seems to come and go as it pleases, but usually comes back only when getting up to speed.

Now yesterday after starting, it gave me an error message of "Transmission Fault" - only turned on once and I can't get it to turn on again...

Thanks for any insight!

Loose wheel, damaged tyre, knackered UJ, wheel bearing failure. Easy things to check for starters.
Oil level OK in auto box and transfer box?

Checked the levels, everything is right where it should be. Oil is a bit dirty so will change it out and see if it makes a difference. Last change was about 3k miles ago.

Tyres are in great shape (new this year) and alignment is good - doesn't pull in any way.
