Hub and bearing assembly?
The size of the nut that holds the front wheel bearing assembly on a 1997 Pontiac Grand Prix is typically a 30mm. It is important to use the correct size socket to avoid rounding the nut during removal or installation. Always refer to the vehicle's service manual for the most accurate specifications.
the nut is metric, I think it is 32 mm , how ever a 1 7/16'' standard socket will work
That would be a clutch fan hub and bearing assembly.
No,NO,NO, The NUT that's on the front axel is what holds the WHEEL BEARING TOGETHER. IT has to be there.
The front wheel bearing is pressed onto the spindle of the and this needs to be done at a facility (machine shop, dealer, auto repair, etc.) that has equipment to do this. The piece that holds the bearing can be removed from the car and taken to the afore mentioned places. Otherwise, you'll have to take the vehicle in.
It is called the front clip. The entire front assembly from the firewall forward is the front clip The nose with the grill and headlights is called the header panel.
185 to 260 ft lbs this is the front center nut that holds axle and front wheel bearing together not wheel lug nuts
Remove lug nuts & tire, remove rotor. Then must remove brake caliper - 2 bolts. Then must remove hub bolts behind rotor that holds hub to steering knuckle, 3 bolts. Remove bearing hub assembly and wiring attached to it. Takes experienced mechanic 1/2 hour or so.
If you want the front WHEEL BEARINGS to come apart and the wheel hub to come apart you can. The end of the axel shaft slides through the bearing hub assembley and when you put the nut on the axel and torque it to 150 ft LBS, That is what holds the front bearing hub together.
You'll need a 36mm socket to remove the bearing hub hub (from the end of the cv shaft). Loosen CV shaft 36mm torque nut prior to lifting vehicle. Loosen (don't remove) wheel lug nuts from wheel. Jack up front end of vehicle until both front wheels are off the concrete. Place jack stands underneath the vehicle. Remove the lugs and wheel from the hub. Remove the brake caliper and rotors (hang caliper with wire from strut/spring assembly to keep the brake line/hose from stretching). Remove the rotor from the hub. Now, with a separate jack, raise the control arm until the point that the cv shaft is level (not angled into the bearing hub). Remove the ABS sensor electrical plug. With 1/2" socket, remove the (3) bolts from the back side of the steering knuckle, which holds the bearing hub assembly in place. It will be tricky accessing these (3) bolts with a socket, extension, and ratchet, due to the very tight quarters, but you can do this, as I have. After removing these (3) bolts, finish removing the cv shaft hub nut, and the bearing hub assembly will remove from the cv shaft. Assembly is the reverse of the above procedure. Be sure to torque the (3) bearing hub bolts to the proper torque, as well as the bearing hub nut to cv shaft. Total time for a good mechanic: about 1 1/2 hours. A novice or beginner: about 2 1/2 hours.
The " King Pin " is on the front end . It holds the wheel assembly on the frame of the truck - one on each side .
