OK so I replaced the front wheel bearings it has made no difference, still rumbles when braking from highway speeds.
- Flex discs (looked OK no cracks)
- transmission mount
- engine mounts
-rebuilt prop shaft and center bearing
All replaced 7 years ago when I had the transmission rebuilt.


Since I had the car up on the Jacks yesterday and during test drive noticed that now a slight rumble exists when the car is in gear at idle intermittently.

Failed engine or transmission mount already? I only use Lemforder or OEM suppliers for any rubber parts where available, never Uro.

While under the car checked the rear suspension and know already that I need to plan for new control arms, links, and subframe mounts while I'm at it. Placed a jack under the diff and lifted, one of the diff mounts moved about 2mm, so those too.
