I removed large hub nut and back 4 hub bolts. I can't get the hub and rotor to come off. Do I need to disconnect the ujoint? Should I knock out the studs then remove the hub separate from the rotor?

 

never worked on one so this is really a WAG, but i'd suspect you need a puller. is the axle splined thru the hub? if it is you'd need a puller. do you have a manual? i'd guess not since you're asking this. ought to buy a manual for it, it'll make life a lot easier for you.

 

Dodge RAM? Give it a few more months and it will probably rust off and come up through the hood (read the recall/TSB list for those "tough" trucks - that part about the front suspension rusting apart).

I think you're going to need to pull the hub on that one. Is that an Eaton front axle?
