Grinding Sound after driving on freeway
Hi,
I have noticed something strange with my TJ. After coming to a stop after being on the freeway, there is a grinding sound/feeling coming from the front wheels/diff. It's more noticeable when turning right after freeway driving.
What makes this odd, is that I drive on normal suburban streets on the way to work in the morning due to low traffic - and I don't feel/hear any trype of grinding. It's only after driving at continuous speed for a while that seems to bring it on.
It seems to go away after the car has been left for a while, which leads me to believe that there is a build up oh heat somewhere.
When driving short distances around home the car travels fine.
I have recently changed the discs and rotors, and my mechanic checked the wheel bearings and all uni joints - there doesn't seem to be any excessive wear. The diff oil was changed only last year.
Any advice would be greatly appreciated.

I was going to suggest wheel bearings - is the rim hot to touch after the noise happens?
Most common way to check wheel bearings is jack up the front, grab the wheel at 12 o'clock and 6 o'clock and if you can rock it, the bearings are shot.

That was the first thing I checked - very little play when doing the wheel bearing check. I have not checked the rim temp though - I'll check it this arvo

Sometimes the calipers produce a grinding sound if they are worn already.
