They are pressed in and need to be either pressed out and in on the vehicle or remove the spindle and brought to a press to do this.
The front wheel bearings are a sealed bearing. You will have to remove the hub from the spindle, remove the lock ring (aka C clip), and press out the bearing. Installation is in reverse order but with a new bearing. YOU WILL NEED A SHOP PRESS TO REMOVE THE BEARING AND THE BEARING RACES.
You will need to take the front spindle off and take it to a shop that can press your old bearings off and new ones on.
Hey Roseanne==First, jack up the wheel then remove wheel, then the caliper. Then remove the dust cap over the spindle nut. Then remove the spindle nut and pull the fub and rotor off of the spindle. If the races thst are in the hub are scored remove them with a punch and install new ones. Then replace the inner bearing and NEW seal and put on the car and replace the outter bearing and spindle nut. Torque the nut to seat the bearing then back it off until there is slight play in the bearing. Pack the bearings before you install them and don't put excess grease in between the bearings or in the dust cap. GoodluckJoe
The front wheel bearings must be pressed into and out of the spindle/hub assembly. You will need to take the spindle assembly to an automotive machine shop to have this done.
The front bearings are pressed into the hub. Take the axles out of the hub and remove the steering knuckle/hub assembly. Take them to a machine shop and have the bearings pressed out and back in again. The rear bearings you just take off the grease cap. Unstake the keeper washer and take the nut off. Then you can pull the outer bearings out. then replace the nut on the spindle and pull out again which will take the inner bearing out along with the seal.
First, lift up the front and take off the wheels with a tire iron. Next, unbolt the brake caliper using the 3/8-inch ratchet and socket, pull it off the spindle and hang the caliper by the upper control arm. Then, remove the dust cap using a hammer and flathead screwdriver and remove cotter pin in the middle of the spindle using the cotter-pin puller. Finally, unbolt the spindle nut in the middle of the rotor pull the rotor off the spindle and remove the bearings on both sides.
They come assembled-all you do is grease them put in rotor and slide on spindle for disc brakes.
TO CHANGE THE WHEEL BEARING ASSEMBLY YOU NEED TO REMOVE THE WHEEL THEN LOOSEN THE SPINDLE NUT. REMOVE THE BRAKE CALIPER AND BRAKE ROTOR, ON THE BACK OF THE BEARING ASSEMBLY REMOVE THE THREE BOLTS THAT HOLD IT IN PLACE. UNPLUG THE WHEEL SPEED SENSOR IF APPLICIBLE. REMOVE THE SPINDLE NUT. THATS THE BEST I CAN REMEMBER, ITS BEEN A WHILE.
Front or rear?
Remove the center bolt for the C/V joint... remove rotor and brake caliper, there is 4 bolts that holds it on, remove the bolts and it will come off and install in reverse order. ============================================================== This isn't true for say, a 1989 Acclaim which has the front wheel bearings pressed it, as well as held in by 3 bolts into the spindle. This I know as Ive replaced both my front hub (wheel bearing) assemblies on my 89 Acclaim LX. ~Technologic80
The front wheel bearings, of a Pontiac vibe, can be replaced by first removing the front wheel. Next, remove the axle end cap. Remove the bearing and reverse the process to install the new bearing.
