Ken, it works pretty good. I got mine at Camping World. Depending on the level of the ground, you might have to put a 2x6 under it to help raise the rig high enough to get the other wheel off the ground.
Just reading older posts and saw this. Cars have two bearings on the spindle, not one. You need to remove the outer bearing and grease as noted above, but the inside bearing needs to also be greased even though it is press fitted and harder to get to.
