Bearing catalog number 2121-3103020-10/6-2007108-A
We carry out the work on an inspection pit or lift. We hang up the front part of the car and remove the wheel.
We disconnect the caliper from the pad guide (see Disassembling the front brake mechanism) and tie them with wire to the upper arm.
We unscrew the adjusting nut of the hub bearings (see Checking and adjusting the clearance in the bearings hubs).
We take out the conical bushing.
Use a chisel to bend the edge of the locking plate of the nut of the front mount of the lever to the steering knuckle.
Similarly, we unlock the nut of the rear mount.
Use a 19 mm open-end wrench to unscrew the nut of the rear mount of the lever to the steering knuckle. Similarly, unscrew the front mount nut.
Remove the locking plate.
After removing the lever from the bolts, move it away from the steering knuckle.
Disconnect the brake hoses from the steering knuckle.
Disconnect the upper and lower ball joints from the levers (see Removing the upper ball joint, and Removing the lower ball joint).
From the splines of the outer joint housing of the front wheel drive, remove the steering knuckle assembly with ball joints, hub unit and brake disc.
Disconnect the steering knuckle and hub with the brake disc.
If you have difficulty separating the parts, clamp the steering knuckle in a vice and knock out the hub with a soft metal punch
Now you can remove the bolts that secure the lever to the steering knuckle
To separate the hub and the brake disc, screw the nut onto the stud and knock out the stud.
After unscrewing the nut, we take out the file. Similarly, we dismantle the other studs.
We separate the hub and the brake disc.
Use a chisel to knock off the mudguard ring.
Use a 10 mm wrench to loosen the protective cover mounting bolt
Remove the casing.
To remove the seals and hub bearings, clamp the steering knuckle in a vice.
Pry the seal with a screwdriver and remove it.
We take out the ring.
We take out the inner ring of the outer bearing with separator and rollers.
Also remove the oil seal, ring and inner ring of the other (inner) bearing with the separator and rollers.
We knock out the outer ring of the outer bearing with a punch and remove it.
Also knock out the outer ring of the inner bearing.
Assemble in the reverse order.
Before installing the bearings, clean the inner cavity of the steering knuckle from old grease.
Using a suitable piece of pipe, press in the outer rings of the bearings.
Put 40 g of Litol-24 grease into the cavity of the steering knuckle and into the bearing separators.
Using a suitable piece of pipe, press in seals
After installing the mudguard ring, use a chisel to press the metal of the ring into the groove of the steering knuckle in several places.
Having connected the brake disc to the hub, we press in the studs with a soft metal punch.
The heads of the studs with a milled surface should be facing the cylindrical surface of the brake disc.
To prevent the bolts that secure the lever to the steering knuckle from falling out when installing it on the car, screw nuts onto them.
Having inserted the tail of the outer drive joint into the splines of the hub, mount the steering knuckle.
After assembly, adjust the clearance in the bearings (see Checking and adjusting the clearance in the hub bearings).
