How To Install Lug Bolts

the best option is to remove the hub as it requires punching out the broken sections and punching in new studs
they are splined formed under the head and require a heavy hammer to drive them in so using something like a heavy tube ( long socket) big enough to miss the head will prevent damage to the rest of the hub

take tire off, take brake caliper off, remove rotor, take nut and bearing off, then hammer out old studs and hammer in new ones. Tim

Hub and Bearing Removal & Installation NOTE: The removal and installation of the wheel bearing and hub from the steering knuckle is only to be done with the steering knuckle removed from the vehicle
To Remove:

1. Remove the steering knuckle and hub and bearing assembly.
2. Remove a wheel lug stud from the hub flange using a C-clamp and Adapter Tool 4150A or equivalent.
3. Rotate the hub to align the removed lug stud with the notch in the bearing retainer plate. Use a proper C-clamp and adapter tool to press out one of the lug studs
   
   Rotate the hub in order to remove the lug stud
   
   
4. Rotate the hub so the stud hole is facing away from the brake caliper's lower rail on the steering knuckle.
5. Install ½ of a Bearing Splitter Tool 1130 or equivalent between the hub and the bearing retainer plate. The threaded hole in this ½ is to be aligned with the caliper rail on the steering knuckle.
6. Install the remaining pieces of the bearing splitter on the steering knuckle. Hand-tighten the nuts to hold the splitter in place on the knuckle. Proper installation of the bearing splitter
   
   
7. When the bearing splitter is installed, be sure the 3 bolts attaching the bearing retainer plate to the knuckle are contacting the bearing splitter. The bearing retainer plate should not support the knuckle or contact the splitter.
8. Place the steering knuckle in a hydraulic press, supported by the bearing splitter. Properly support the steering knuckle for hub and bearing removal
   
   
9. Position a driver on the small end of the hub. Using the press, remove the hub from the wheel bearing. The outer bearing race will come out of the wheel bearing when the hub is pressed out of the bearing.
10. Remove the bearing splitter tool from the knuckle.
11. Place the knuckle in a press supported by the press block. The blocks must not obstruct the bore in the steering knuckle so the wheel bearing can be pressed out of the knuckle. Place a driver on the outer race of the wheel bearing, and then press the bearing out of the knuckle.
12. Install the bearing splitter on the hub. The splitter is to be installed on the hub so it is between the flange of the hub and the bearing race on the hub. Place the hub, bearing race and splitter in a press. Use a driver to press the hub out of the bearing race.

To Install:

1. Use clean, dry cloth to wipe and grease or dirt from the bore of the steering knuckle.
2. Clean the rust preventative from the replacement wheel bearing using a clean, dry towel.
3. Place the new wheel bearing into the bore of the steering knuckle. Be sure the bearing is placed squarely into the bore. Place the knuckle in a press with a receiver tool, C-4698-2 or equivalent supporting the steering knuckle. Place a driver tool on the outer race of the wheel bearing. Press the wheel bearing into the steering knuckle until it is fully bottomed in the bore of the steering knuckle. NOTE: Only the original or original equipment replacement bolts should be used to mounting the bearing retainer to the knuckle. If a bolt requires replacement when installing the bearing retainer plate, be sure to get the proper type of replacement.
   
4. Install the bearing retainer plate on the steering knuckle. Install the 3 bearing retainer mounting bolts. Torque the bolts to 21 ft-lbs (28 Nm).
5. Install the removed wheel lug stud into the hub flange.
6. Place the hub with the lug stud installed, in a press supported by Adapter Tool C-4698-1 or equivalent. Press the wheel lug stud into the hub flange until it is fully seated against the back side on the hub flange.
7. Place the steering knuckle with the wheel bearing installed, in a press with special Receiver Tool MB-990799 or equivalent supporting the inner race of the wheel bearing. Place the hub in the wheel bearing, making sure it is square with the bearing. Press the hub into the wheel bearing until it is fully bottomed in the wheel bearing.
8. Install the steering knuckle and the wheel.
9. Check and/or adjust the front alignment.

You require "lug studs" to be able to install a lug nut to secure the tire.

You will need a special tool to press the lug studs in and out of the flange, or you can follow these directions;

First you will have to pound the broken lug stud(s) out of the wheel hub, use a punch or a drift that is a little smaller in diameter than the lug stud, and be sure that you do not pound on the flange itself, then you will need a lug nut and about a half an inch thick of flat washers.

1. Insert the new lug stud through the wheel hub from behind so that the threaded end is facing out towards you and then put some grease on the threads.

2. Then slip the flat washers onto the lug stud followed by the lug nut, and run the lug nut down backwards with the flat end of the lug nut towards the flat washers to take up the slack and use plenty of grease on the threads.

3. Then using a breaker bar tighten the lug nut until it pulls the lug stud through the wheel hub and it is flush with the wheel hub.

Be sure that the amount of flat washers used will make up for any non-threaded part of the lug stud that might stick out past the wheel hub preventing the lug nut from pulling the lug stud all the way through the wheel hub, and basically you do not want the lug nut to run out of threads before it can pull the lug stud flush with the wheel hub.

Let me know if you require any further assistance.

HI:
Stop!!! The "round plate" that the wheel studs are mounted to is your hub assembly. To replace a broken stud, you simply need to use a hammer and a drift pin punch, and pound it backwards. You replace it in similar fashion: insert the new wheel stud in from the back side of the hub, and use the wheel lug nut to draw the new stud into the hub assembly.

I'll try to help you. If you are having trouble with 3 out of 5 studs on one wheel you may want to go to an autoparts store or Salvage yard to look at the whole hub. Usually a press is used to remove the bolts so you would be taking off the hub anyway. When you pay for 3 bolts and labor you may be better off in a Salvage yard or parts place for a different hub. The rear hub on front wheel drive cars is like a trailer axle. Much simpler to remove mounting bolts and press in new bolt. But if rear has differential(rear wheel drive) it has an axle shaft. Would be easier to grind and drill out broken stud on car. You can draw new bolt into place by placing bolt through a socket and use the wheel nut to draw the bolt into the hub.

take off the wheel and remove the axle. knock out the bad lugs and press new ones in with a big vise or shop press

there is a large nut that holds that hub on. Remove the cotter pin and the cap from the bolt... remove the bolt and the hub comes off.

Which bolt(s) is sheared ?

Please clarify.

Thank you.

lugnuts and wheel studs
you will have to pull the barke drum off and knock the studs out and should be able to get new ones in and use a nut and spacer to pull the new studs tight
