Replacing front wheel bearing, need front and rear?

[SUX2BU99]

Might be a dumb question but just thought I'd ask. I have a noisy wheel bearing on the front passenger side. I can see the grease melted out of it too, due to a hanging caliper. I'm replacing the calipers with new loaded ones, turning the rotors and replacing that bearing. I presume I need to replace the bearings on both sides of the rotor, as it's a 2-piece set?

I'll have to get the bearings out of the rotor. Best way to do that? Pry them out or?

each hub has an inner and outer bearing, each bearing will have a race.  the bearings are different sizes, inners are larger and outers are smaller.  depending on the bearing maker it may or may not come with the race.  Timken bearings should come with the races. 

the inner bearing is held in place by the spindle seal.  the races can be hammered out using punches but its best too use a brass punch so it won't score the race seats.  install using a brass punch. 

you didn't say if its was 2wd or 4wd, but be sure to get your preload on the bearings set to specs and use a good quality grease.

Thanks. It's a 2wd. Maybe I'll get them to replace the bearings when I get the rotors turned.

      Use the manuals in the tech sections for the torque specs if you do not have a manual.

Great, thank you.

Also, when I get them turned, do I need to make sure to have the wheel bearings in place along with the washer and castle nut? I took the passenger rotor off last night and the outer bearing just fell out once I took the nut and washer off.

     They can replace the race's, but the bearings just sit in there, you need to put them in as you are putting the whole assy. back on.

Great, thank you.

      I assume this means having the rotors turned ?  Do not put your new races in before they turn them, the bearings will need to come out but leave the old races in and clean up really good then have them turned.  Nobody likes to work on greasy stuff.

Awesome, thanks for the reply. They were well-greased in there!
