Diff Bearing Gone?
Posted 17 May 2010 - 08:53 PM
My focus has developed a very loud whining noise.
It starts at 15 or 20 mph and the volume increases with road speed (not revs). It doesn't seem to change with steering input.
I checked the wheel bearings and they feel reasonably smooth and have no play in them.
I also removed the right-hand drive shaft and checked the bearing that sits half way down it, it feels nice and smooth too.
So I went on to check the diff bearings. I can feel a bit of play where the left-hand drive shaft enters the diff - is this normal, or is my bearing knackered?
If it is knackered how hard is it to replace? Can it be done in-situ or will I have to remove the gearbox?
Also, how do I remove the left-hand drive shaft from the diff? The right hand side came straght out, but the left hand one won't budge.
Have something to contribute?
