R you all forgetting about big bertha. Reg you will be paying around 100 for each. I replaced both of mine. You can get the cheaper ones if you want, they should work. And yes, Al is right antisieze the shit out of them. If you leave the breaks on to break the nut free, you can have someone step on the breaks, come up to shop and borrow Big Bertha. Use her to break it free and you don't send shit flying, break or damage anything and u don't sweat alot. The whole job I can do in about 20 min per side at the shop if no one stops me or gets in my way. We just did a bearing on Erick's deisel tonight while working on Axle's driveshaft. And yes you will probably need hammer and chisle. We have done them up at the shop as a club too on either a yellow jeep or Ben's rig, I can't remember. We put axle shaft seals on the same rig, it was one of the days where we worked on like four vehicles in one day.
