Rear axle oil change.

[Dave Mann]

I sometimes have oil leakage from the either side of the diff case and find that the setscrews want nipping up. I thought the general opinion was not to fill the diff up to the filler plug to reduce the risk of oil leakage down the shaft to the brakes, whilst this isn't critical on the banjo axles with a vent on the diff case it is on the D type axles with the vent plug on the torque tube.
