I've changed several front bearings on my 85 4000Q and my '95 90Q. It's
not a bad job. A 12 Ton press
makes it very easy. I've used greased threaded rods and various peices from
Home Depot as well. If you have room for a small press it's a good thing to
have for wheel beariings, lower control arm bushings and such.
The only trick it to make very certain that you press the new bearing in
straight and watch very carefully not to get it cocked in the housing.
The first shot at doing it could take the better part of a day to
assemble the right sized pieces of pipe and stuff to press the bearing but
once you have that sorted out it's a pretty quick job.
Harbor Freight has a 12 ton press for $99. With that and some of their
bearing and seal press kits I can do a bearing in less than 2 hours, start
to finish, if I take my time.
I have done them for mine and friends about six times.
I have done it like Gene described but there is a bearing puller tool
available that allows you to do it without removing the strut.
Pull the strut:
Remove the wheel and the axle nut (takes a big breaker bar and a six
foot pipe extension) I think that it is 32 mm but I use a 1 1/8 inch socket
Remove the tie rod end.
ABS sensor (check the position closely so that it is same dimension from
the pick up ridges when replacing it.)
I use a six foot 4X4 to pry the sway bar down when removing the lower
control arm bolt. Most others drop the sway bar but that is a bit of a
Hold strut when removing the three nuts from the top and it is out.
The bearing has a large snap ring in and out. A snap ring pliers with a
lock to hold tension when you are taping to loosen it is a big help.
Use appropriate chunks of steel in the press to CAREFULLY press the
bearing out. Carefully because it takes a lot of pressure and you don't
want to launch it when you are in the way.
I have removed and replaced a bearing with a BFH and a punch. It worked
better than I expected but a press is strongly recommended.

Does it change pitch or intensity when you veer/turn left or right? It
should if it is a front wheel bearing!
IIRC The right side would get a little quieter when you turn right, and
noisier when you turn left.
I agree with you and the others and it could be the wheel bearing. But it
is good to try to pinpoint it before you attempt repairing it to make sure
it is the right front! Sometimes noises can be misleading. 8^)
Note: If you take that knuckle/strut off with normal tools, you can
probably take it to a machine shop and have them press the wheel bearing out
and in for a small charge.
