well here's the story i fitted new brakes last weekend and after a little while a had this grinding when i turned sharpe either left or right so i took it into garage and they have found that the hubs are different to each other how i dint spot this i dont know but as it goes i need a new hub to mach the other side and the bearings are fooked too.

Juat out of intrest umm i noticed that the back right sits lower than the left why could this be im guessing a broke spring or maybe sezed shock any other ideas??

and i have an anoying rattle sounds like a heat shield or bracket loose something like that but i couldnt find anythin does it on tick over and when im slowing down ?? its just anoying
