I'm trying to remove the rear wheel on my 2007 Suzuki RMZ450. I've removed the axle bolt and tried banging the axle with a rubber mallet for about two weeks now. IT WON'T BUDGE. Not even a little bit. It seems to be completely seized up. What can I do to loosen it up and eventually remove, hopefully saving the wheel bearings at the same time?

First, I have to compliment your stamina. I doubt I'd be able to keep swinging a mallet for two whole weeks.

Soak the area in a good penetrating oil. I like Wurth's Rost Off, but there are many choices. Hit it with penetrating oil once or twice a day for a while. Give it a few whacks with a mallet, if it doesn't loosen up, hit it with more penetrating oil, and come back tomorrow. Repeat until it's off.

Otherwise, I think you might have to resort to using a torch to heat the bearings or the axle. After the torch treatment, I'd replace the wheel bearings.

  • Ha! Yes I'm a modern day John Henry. Thanks for the suggestions, I'll try them out. And when you said "Wurth's Rost Off", did you mean "Wurth's Rust Off"?

    Nope, they spell it "Rost." German company.

  • Ended up having to set a block of wood up against the axle and bang away with a real hammer. Also used a good bit of penetrating oil. Thanks for the help!
