Thought I would throw the die and see what you guys might have on this.
I have a 2010 BT50. 265km. It has developed a vibration through the drive. Universals all good. Engine mounts good. Tyres almost new and the Vibration doesn't come through the steering, but is evident, really evident. Between 1200-2000 rpm. If I travel down the bitumen street in 4WD, doesn't seem to be so bad. I asked the mech if it could be a miss, but he assures me no. I'm waiting to take it to the local Mazda dealership.
