2000 Mazda 626 Front wheel bearing replacement

We have a 2000 Mazda 626 with 108,000 miles and the front wheels are making a lot of noise. I used to have a 1987 Mazda 323 and had a similar problem for which I changed the wheel bearings and it solved the problem. I was wondering how difficult is it to change the front wheel bearings on the 626? Do I need any special tools such as a bearing puller or hand press? If I don't do the work myself what would be a fair price to pay for this work? Any help would be appreciated.

Thanks. Tom
