how do I replace the frint wheel bearings on a 2007 toyota camry xle

I don't advocate changing both bearings unless they are both bad. It's a extra unnecessary expense. I've had some bearing last 50K miles and some only 15K. They aren't made the same and they don't wear the same. To find out which bearing is bad, raise the wheel and spin it by hand in neutral. Grab the spring and if it's bad, you can feel the balls crunching in the race. --- This video should show you how it replaced: http://www.youtube.com/watch?v=1CwL-m5HpPo

Do I have to get the new bearings pressed in at a machine shop or can I put them in myself?

It depends on what tools you have and your mechanical experience. The video shows the steering knuckle being removed and the guy took it to get pressed in. There a clip on the inside that is removed.

Thanks Tenspeed. I have worked on cars all my life thanks to my dad. I think I will give it a go and see how things turn out. I have always used a LARGE sockets to tap the race and bearings in all my previous cars and trucks but this Camry made me stop and hopefully figure it out before I got started. The main thing i wanted to know was if I really needed to have the bearings pressed out and the new ones pressed in at a machine shop..

I don't know, never changed one. You might find some heavy wall PVC pipe that will push that outer race out. Perhaps a circle cut out of 2X4. Soak everything with penetration first, last and often. You could try some heat on the knuckle to get it to expand a bit and soak some oil in. Keep your new bearing in the freezer until ready to slip (pound) in. I usually paint everything with marine grade anti seize so the next time is a little easier.

Thanks again. I am going to do it. I appreciate your help.
