Hey guys im having lots of trouble removing the rear hub assembly from the car to replace them i have tried everything i know of to try to get them to come off but to no avail i've even hit it with a hammer and nothing please help me i have brand new hubs waiting to install and no way of removing them i even went as far as putting the wheel back on and lowing the car in the hopes that the pressure would knock it loose but it didnt it held on firm i managed to knock the shim on the back loose but the hub still holds true, and just in-case anyone is wondering yes i removed all four bolts that hold the rear hub on and had all brake hardware removed.

If you have access to a pneumatic air hammer, take that and put it on one of the triangle shaped back piece, hammer on one of the "lobes". It should rotate the hub and break it loose, then it should be a lot easier to either tap it out or pry it out.

I've used a slide hammer to get them out. Some auto parts store rent them.

Another method is to buy some heavy and long threaded bolts, washers and nuts.
Put bolt through a hole in the hub face, then add a washer or 2, then a nut,
Hold the nut with a wrench and turn the bolt, which presses against the backing plate and acts like a puller of sorts.
Loosen it up and then again turn the bolt to repeat in a spot opposite the first.
You can put a couple of nuts, tightened against each other, on the end of the bolt, to spread the pressure out a bit but I didn't find that necessary.

I know this maybe a long shot but could you draw a picture or maybe have one of what your talking about, I'm trying to picture this but it's coming up foggy maybe some more detail or anything else that might help?

Wrote a detailed reply, accidentally hit a wrong key and it vanished forever.

Basically, you are trying to affix something (the bolt,washers and nut) to the hub face, so that you can tighten the bolt head and have the tip of the bolt pressing against the knuckle with increasing force every time you tighten the bolt, so that it forces the hub away from the knuckle.

PBBlaster and Kroil work nicely to help penetrate the rust that is binding it in place.
Scraping the road crud away can help these to work faster.
WD40 has never worked as well as the PBBlaster does for me.

FWIW a 1/2" Dewalt cordless impact wrench helps to make light work of automotive repairs.
Santa will be bringing me a new brushless motor model this Christmas. The 700 ft. pounds of torque should prove quite handy.
