They are pressed in and out with a set of special tools.
It must be replaced as an assembly with the entire steering knuckle. If you check ebay, there might be just the ball joint for sale, but it will need to be pressed into your old steering knuckle.
Take off the steering knuckle and press out the bearing and hub.Have the new bearing pressed in with the hub and re install the knuckle.
Replacing a steering knuckle on a Chevy Colbalt is easy. All you have to is take the steering wheel off and replace the old one.
Detach lower ball joint from steering knuckle. Remove bolts that secure control arm to vehicle.
No, the bearing is pressed into the knuckle.
You have to have the hub pressed out of the knuckle to replace the wheel studs.
you gotta pull off the knuckle, and have the bearing pressed out, and a new one pressed in
To replace the control arm on a PT Cruiser you must first raise the vehicle, and then remove the front tire and wheel assembly. The stabilizer bar links from the Cruiser and rotate the forward ends of the stabilizer downward. Remove the nut and pinch bolt to ease resistance, follow up by removing the ball joint stud to the steering knuckle. The ball joint stud should be separated from the steering knuckle by prying down the lower control and up against the ball joint on the steering knuckle. Remove in this order: the front pivot bolt attaching the lower control arm; the rear pivot bolt attaching the lower control arm to the front suspension cross-member and frame rail; remove the lower control arm from the cross-member. Replace the bushings, and then reassemble the unit.
remove the wheel. support the control arm with a jack stand. remove the driveshaft/cvjoint nut (the big nut in the center). may need to have someone pressing the brake or at least losen before you jack it up and remove the tire. remove the brake caliper assemby and the rotor. remove the tie rod end from the hub/steering knuckle. remove the two nuts and bolts attaching the hub/steering knuckle to the strut/shock and the nut and bolt holding the the hub/steering knuckle to the lower ball joint. lift the hub off the lower ball joint slide the hub/steering knuckle off of the cv joint/driveshaft. there may be sensors for antilock brakes and such that need removed but it should be fairly obvious on how to remove just by looking at them. with the hub/steering knuckle out, the bearing is a sealed bearing and is pressed out of the center after removing a seal and the new one is pressed in. since i don't own a press, i would usually take it to napa autoparts or someplace that has a machine shop and have them press the new one in for me. then reassemble.
I am not familiar with this car in particular but ball joints are either pressed in, bolted, or riveted into the control arms. On top of the ball joint is the steering knuckle, usually the ball joint is held into the steering knuckle with a pinch bolt. Which is easily removed. After the pinch bolt is removed you must force the control arm away from the steering knuckle which sometimes requires the use of an air hammer. Depending on what type of fit the control arm has with the ball joint, you will either need a special tool to press out the old ball joint and press in the new one, if the ball join is a press fit. Or if it is riveted you will have to carefully drill out the rivets and replace the new one with bolts. If it is bolted in you simply loosen the bolts and knock out the old ball joint. Installation is reverse.
Their are two ways, first of all you need to remove the whole steering knuckle from the vehicle. First remove the brake caliper, and brake rotor. Then remove the axle from the knuckle, the two top bolts from the strut, lower control arm, and the outer tie rod. Then at this point you can just replace the whole knuckle. Or, the bearing sits in the knuckle behind the part where the rim would normally bolt to. It is a pressed in bearing, so in order to remove it you would need a press, hydraulic or manual. Face the knuckle downward, and with the proper press tool press the bearing out from the top until the spindle drops out, then press the bearing off the spindle. You can now reverse the process to install the new bearing.
Your best bet is to remove the steering knuckle then take it to your local machine shop as the wheel bearing must be pressed off the hub and the knew one pressed on. Also a front end alignment shoudl be performed afterwards Good Luck Remove the front wheel knuckle Remove the inner wheel bearing oil seal Use Bearing Pulling Attachment to press the wheel hub from the wheel knuckle. Remove the retainer ring from the wheel knuckle. Use bearing puller attachment to press the wheel bearing out of the wheel knuckle reverse the removal procedure. install new inner seal
