What problems can be caused by this part?
Oil leaking from final drive
Oil appears to be leaking near the back of the car in the centre, on inspection it looks like it's coming from the part that meets the drive shaft. This is a problem with rear wheel drive cars.
Screeching or creaking sound under car
When the car is in gear and driving along there's a screeching and/or a creaking metallic sound coming from under the centre of the car. The sound will change and get worse as the car moves and accelerates.
