Wheel Bearings

At the last inspection they told me that all 4 wheel bearings will need to be replaced soon.
The garage wants $350 per wheel!!!!
Is that right?
Can I do this myself?
Thanks in advance

Thats quite a bit high I just had the driver side front wheel bearing in my Stealth, which for all practical purposes is identical to a 3000Gt and it cost me right around $150 to have it replaced. So I would talk to some other garages. I thought about doing it myself but I had no idea how to do it so I just had the shop do it.
