WD

I'm working a bit on my Dad's WD. The rear end oil has not been changed in.....forever. Should I put 80-90 in there? or something else. Also, I'm thinking it would be best to drive it some on a hot day to try to heat that up a bit to get it drained out. Any suggestions? Thanks

You can put 80w-90 back in or use hy-tran fluid. Personally if I would put the gear oil in if you're going to work it hard but either will work fine. Getting it warm will definitely help it drain but isn't necessary. If you drain the bullgears put gear oil in them.
