Rear wheels seized on

[BryanKaren]

I just picked up and old 1992 f150. I have been getting it all ready for a saftey. I tryed to get the back wheels off to look at the brakes. But guess what they are seized on there really good. I have been ponding on them whis a sleg for about 2 hours today and, not a thing. Any have any ideas?

By seized on do you mean that you have removed the lug nuts but the rims will not separate from the axle flanges? If this is the case heavily soak them with WD40 and let it sit for a day.

My only other suggestion is to take the diff. apart and disconnect the axles then slide the whole thing out and deal with it from there.

I did the wd40 thing no luck. Trying to avoid taking it all apart.

Are your rims rusted onto the brake drums?

I think Torch hit the nail on the head with the rust. I get em here all the time like this, both steel and alloy wheels. Its a big problem here close to the gulf, the rust and corrosion build up between the pilot holes in the rim, and the axle flange. You can take a hammer and chisel and chip away the rust from the boss on the axle flange, or use a dremmel tool with a carbide bit. Then take a torch and heat the center portion of the wheel around the pilot hole. This will expand the center of the wheel, and pop the rust loose. Be careful if its alloy wheels and dont get em too hot, and wear glasses, when that rust pops loose it can put your eye out. Once you get em off, clean the rust/corrosion from the axle flange and the wheel, and use anti sieze , or at least a little grease if you dont have anti sieze.

What I was going to suggest is that you get into the brake adjusting hole on the back side of the brake assembly and back the brake pads away from the brake drums far enough that the brake drums will slide off with your rims.

How you do this varies from car to car, on my old 77 F-250 there was a little bar that caught on the star wheel, you had to pry the bar up with one screw driver then then back the star wheel up with another one until the brake pads were out of the depression they had made and then the brake drum would come off.

But, then there is still the problem of separating the rim from the brake drum so heating it up as UncleBubbles said might be a better idea. Also like he said use anti-seize or something else when you put it back together, white lithium grease or marine grease (it is water resistant) will also work.

Thnax all I got the wheels off. I used lots of oil and a big hammer

Glad to hear it went well.
