Hello.

Just this morning my freelander has started to make a rumbling noise when hit 55mph and the whole car vibrates. Its also making a bad rumbling noise going round left corners.

It had new propshaft bearings about 5months ago.

can anyone please advise what it could be before i try to find a garage to look at it (my usual garage have mucked about my brakes so not going back).

Check tyres in the first place. Maybe a balancing weight has been thrown off or flat spots have developed.

If your brakes have been worked on recently have them checked again by someone else. I recently had a similar problem to yours caused by a dirty caliper piston. I fitted new discs and pads and then caliper was becoming stuck causing respective side to stick on. As speed increased the heat was causing disc to 2arp. Cleaned up caliper piston and all tickety boo. What brand of prop shaft bearings did you use? Some are known to be very poor quality.
