Rear-end lube change

Thanks all.....I used that 5 gallon estimate from another forum talking about the fluid change. Ill dig out my paperwork before the actual purchase and/or drain it first to see the approx amount that comes out.

Hey Fred, good idea on the drill pump....I had read someplace else about using that exact method for draining the Hydraulic resevoir(think it was an old video from Brett Wolff)....thats another project.
