94 Firebird Rear Wheel Bearing

Thanks guys you have been so much help.my last little escepade was the check engine light the problem was I felt like I had no power like the transmission was slipping.well after some more fiddeling around with it in the driveway I noticed I had overlooked the obvious the transmission was slipping it was very low on tran fluid I put some in it and after that the service engine soon light hasnt came back on since Im trying to get the bugs out of this car I like it very much I think the other owners have neglected it over the years,well my latest problem is the right rear axle bearing,or wheel bearing sounds very bad, is it hard to change?:icon16: I like to do it myself the book makes it look easy but I would like your input on the situation ,I still have the one hideaway headlight that works when it wants to but I think I can fix that,and the last thing,for now Im getting strong feul oder while driving and when I park.so let me have it and have a great day.
