2007 Ford F150 Wheel Bearing Replacement Problem
My niece has a 2007 Ford F150 and needs to replace the wheel bearings on the front
right. While my nephew was removing, the wheel nut is fused to the spindle, any
suggestions on how to get the wheel nut off? Will heat work? We tried a 1/2 drive breaker
bar and actually broke it off...
1. You can try Liquid Wrench and then a little heat. You can use a 18" pipe wrench of very good quality with a steel pipe about 3 feet long, with the hole just a little bigger than the pipe wrench handle for adding torque to break nut loose. Pipe should be schedule 80 for breaker bar on pipe wrench. 2. There is such a thing as a nut splitter which will definitely work. These can be purchased at industrial supply companies like MSC industrial supply. Do not buy at a hardware store, industrial supply companies will sell the better quality splitter, and you can purchase on line! Good luck!
If that nut is fused to the spindle, there is a very good chance that the spindle is ruined. I would bet that the bearings are also welded into place. Those bearings were run way past any safe limit to produce that much heat. I would use a nut splitter and crack the nut off, and then very carefully inspect the spindle. If the spindle is discoloured, plan on finding a replacement steering knuckle from a wreckers. As an aside, front wheel bearings are meant to be repacked each time a brake job is performed. Always use a high quality bearing grease that is able to withstand the heat, and always install new grease seals, after you ensure that all of the old seals have been removed from both the disc and the dust shield.
The Wheel Bearings on this particular vehicle are sealed an part of a hub assembly. No seals, repacking or grease. I have never seen this concern. The center nut is very tight but normally, it comes right off. You could remove the knuckle and take it to a machine shop to see what they can do for you otherwise, You may end up replacing the entire knuckle. Sorry.
First question, is this a 2 wheel drive or a 4 wheel drive? If 2 wheel, I stand by my answer. If 4 wheel, then Tracy is likely correct.
Most Ford F-150's require the nut holding the bearing on to be replaced everytime it is removed. I replaced one on my sisters F-150 and it was a pain to get off. The Ford mechanic from down the street stated they are made that way. He is the one that got it off. He came walking down the street with a breaker bar that looked like it was meant for bridge construction. Also, I believe he stated the new nut must be torqued to about 200 pounds. No wonder it is hard to get off.
Oh, and if memory serves the new nut is about forty bucks or so.
$40 is a lot cheaper than a full spindle/knuckle repair/replace.
I owned an '05 F150 and have replaced brakes, and inspected bearings before. It can be done. Also, even if spindle is discolored doesn't always mean ruined. A thread chase or appropriate die will clean up threads. You can also remove bearing inner race by grinding almost through the race, then use a good cold chisel and hammer to to crack race and remove it.
But there is no inner or outer race to remove on this sealed hub assembly.
