Front hub assembly

I have a 2000 F-150 4x4 with disc brakes on all wheels. My driver's side wheel bearing assembly has gone bad and I am trying to replace it. I have removed the caliper and the three bolts on the back of the hub. I have also removed the large 35mm nut mounted on the shaft. Here is the problem, I have applied "judicious" use of a large hammer on the back of the hub, but have not been able to jar it loose. Am I missing something here? Or should I get more serious about beating the daylights out of it?

Thanks is advance for any help,
Tom

this might be dumb but have you removed the cv shaft from the bearing assembly? might help i don't know. I took my whole front end apart on one side doing ball joints, why i don't know, but it came out easier that i thought actually. try spraying some aero-kroil or pb blaster if you have some

after loosening the 35 mm nut, the shaft should push inward 1 inch toward the motor. that shows you the splines are not stuck. if it wont push, tap on it a little, if its stuck, you need to bolt a pusher plate over the studs and use the center jack screw to push the half shaft inward. once it is loose, your right, the hub just pops out. you may have to use a pointed chisle to drive between teh knuckle and the hub to get a gap. normally hitting the hub a few times will start it moving. good time to check lower ball joint also.

Thanks, guys. The shaft floats in the hub, so I don't think that is part of the problem. I will now apply the pointed chisel method and see how that works.

I've found that PB Blaster, a wood block, plus a BFH on the side of the flange is also needed at times.

If you are replacing it, I wouldn't be afraid to wail on in as long as you are using a wood block.

Becareful of where you hit, and don't miss!

Knock the crap out of it!!!! Hit it from various directions, not just in one spot. Be generous with the penetrant!

haha heres a question for ya. when does a hamer get to big? .... when you cant pick it up. when the bfh fails, go for the RBFH. also an air chisel (sp) isnt a bad idea. use it like the chisel and hammer. it may not seem like it but man that vibration can work some ***** lose.
