99 Galant Rear Wheel Bearing

I need to replace a rear wheel bearing. It's making quite a bit of noise.
I'm fairly mechanically inclinded, so I'd have no problem doing it myself,
but I need a book or some instructions on how to do it (tired of paying a
mechanic).

Can someone point me to a good repair manual or online instructions on how
to do this (if it's something your average Joe can do without any
specialized tools).

Thanks!

Seems a bit like a stupid comment, but I had a similar experience with my 97
Galant.
I'm a mechanical engineer whose daily work consists of working with bearings
in a chemical plant, so I should know my business.
When I heard a noise from the left back it sounded 100% like a bearing.
Dealer said it could only be replaced as a package, which would cost up to ?
600 ($ 675).
After an inspection he came back with the solution: replace your
rearwheeltyre... Like I dont know a bearing from a tyre!!
As an unbeliever I silently changed tyres with the spare... the noise was
gone !!!
It appeared the tyre was "cupped" with enough profile to last another 20,000
km. Due to my drivingstyle (I think) or a bad tyre, the tyre has got "teeth"
around sticking out, that make the same noise as a worn bearing.

It was the best solution though to get rid of the noise, and a lot cheaper.

Morale of the story.... be sure it's your bearing, before you end up with a
costly repair that does not solve your problem....
