Does the axle bearing on a 1999 ford F-150 have to be pressed into the axle tube?
The answer is no. I have changed mine twice in the last six
months. All you do is use a large socket to tap the bearing back
into the tube. Be sure to make sure the bearing goes in straight
and tap squarely on the socket. Make sure your bearing doesn't go
in at an angle. If you haven't removed the old bearing yet, you
will need a removal tool that looks like a dent puller. These can
be rented at Advance Auto.
