Ever since I've owned my D I always had that axle oil leak on my drivers side after putting the car back in the garage. I replaced the seals and there was no change.
Well I recently changed from using MOBIL ONE engine oil to ROTELLA 15-40. It looks like that stopped what I thought was the axle leak. I guess my leak was the rear main engine seal but it would drip to where I thought it was the drivers side axle.
