For jeeps, wedge a grade 8 bolt and nut between the steering knuckle and the ujoint ear. Turn the steering wheel and it will pop the hub off.

Well I used it yesterday. The lisle 38210 set. I bought it from Carquest

http://www.tooltopia.com/lisle-38210.aspx

Couldn't imagine taking the hubs out without this set. They were rusted solid along the surface which sits in the knuckle. Two to three minutes of hammering with a CP 4444 rivet gun (clone) on the bolt flanges and they were out 1/4". Put a chisel in a took it out the rest of the way. Paid for itself easily. Highly recommended. Just put the dust shield on the right way LOL

I bought one after changing the front hub on a '99 dodge 2500. Have not used it yet, but it should work great based on what I've seen.

I think it would also work on exhaust manifold bolts/nut's (flange type) to shock them loose.

Then there is the socket and extension methoed used to remove the wheelbearing.Snap On makes the special tool for this,the socket and extension metheod works if you don't want to spend the money on the special tool from Snap On.Basically you break loose the wheelbearing bolts an eigth of a turn and put the right size socket with a number extensions lodging them at a sturdy area.Then you have someone start the truck up and turn the steering wheel.Basically you are using the powersteering as a hydraulic press,this works on 1994 to 2001 fullsize Dodge 4x4 trucks.

I use the tools similar to the ones listed by Lisle - they work great. On larger vehicles, I use a large diameter piece of roundstock between the axle housing and bolts of the hub assembly.

As long as the legnth isnt an issue it should work.

With the Lisle bit, you back the bolts out a few turns and use the bit to push on the head 'till it pops the hub loose.

Been thinking about this tool, wouldn't this also work with the appropriate sized socket? Asking b/c I plan on buying it from SO, figured it could pull double duty with any sized bolt for any unit bearing. Thoughts?...

I was going to suggest that. Mayhew sells it as the "shake n' break". You can also use it to hammer on seized bolts to try to break them free or get some penetrant in.

My 95 Dodge 4x4 diesel with the Dana 60 has 12 point bolt heads on the hub units. That Snappy tool looks to be made for 6pt bolts or am I missing something?

Yes, it has a 1/2 or 3/8 drive end, depending on which model you buy. You can use any socket you want.
