Sounds like I should have all the tools. Too bad that gear oil smells like crap tho! Last time I washed all my rags and my washer smelled bad for about 2 - 3 weeks. Im throwing thise rags away this time.
You may need a puller to get the pinion yoke out and when you reassemble, put some Halomar or silicone on the splines of the yoke to keep oil from seeping out between the splines and the yoke.
