Do the hubs pull off axle easy?

Use a puller if you have one. I used a 3 jaw here and it worked fine but a 4 or 2 jaw would have been preferred. Usually your local parts store will loan or rent these tools out if you don't want to buy them.

If you have to use a puller, it's easier to just make one than to try those 2 or 3 jaw pullers. A bar with 3 holes in a straight line drilled through it. Bolt the outside two to jug studs and put a piece of all-thread or a long bolt against the axle, with a nut between the axle and pull par. Hole the nut and tighten the all-thread against the axle and it will put it right off. I had to do the fronts of an LTR a couple weeks ago like that. Took about 5 minutes to make the puller.
