Differential Oil Change
Not a difficult job, but glad I don't have to do it again for a long time. The rear drive axle holds almost 4 gal and the only pump I had was a siphon hose with a squeeze bulb in the middle. That would have worked okay if I had planned ahead on elevating the 5 gal bucket of oil above the axle for a gravity fill. There was room for the bucket just in front of the axle, but I had nothing to hold it in position. So it was about an hour of squeezing the bulb to pump in 4 gal. Another mistake I made was not loosening the fill plug first, but fortunately it was not stuck. Neither of the magnetic plugs had any metal on them. I used a synthetic 75W-90 oil that according to the Rockwell manual is good for 250k miles with no yearly change requirement. Cost just under $125 for a 5 gal bucket including 8.25% sales tax. I drove about 30 miles on the Interstate with an OAT of 85 degrees to warm up the old oil. That was about 10 miles more than I really needed to do as the oil was almost hot enough to burn my fingers. The 1 gal left over is going in the manual transmission on the toad.
