Replacing the rear wheel bearings
From FogWiki
Contents |
Applies to
A Series, leaf sprung (with drum brakes)
Equipment Required
- The Bearinator (or large slide hammer)
- Angle grinder
- Oxy-acetylene torch
- Trolley jack, axle stands
- A good tool kit with sockets, ratchet, pliers, allen keys, etc
- Differential oil
- Brake fluid
- Replacement wheel bearing and retaining collar (available from good Motor Factors for about £45 each)
(The Bearinator is a large slide hammer made by FOG member Weave67. There are now actually 2 and arrangement to borrow one can be made through the FOG discussion forum)
Difficulty Level
- Difficult.
Having taken part in this job, it is hard work and not for the feint hearted
Estimated time to complete
- 6-8 hours (for 2 rear bearings)
Method
- Slacken the appropriate road wheel nuts, chock the other three wheels, raise vehicle with trolley jack and secure vehicle with axle stands
- Reave out of gear and release hand brake
- Remove road wheel
- Remove drum brake (note securing screw)
- Remove brake shoe assembly
- Clamp rubber brake pipe and remove the metal brake pipe from the brake cylinder
- Remove brake cylinder
- Remove half shaft clamp plate bolts
You should now be at a point similar to the above photo. Note the hole in the flange plate that allows for the use of a socket on the half shaft clamp plate bolts.
- Attach the Bearinator (or other suitable slide hammer)
- and give it a few whacks (Heat might be beneficial around the axle casing)
If you are lucky, the half shaft should come out with the bearing and retaining collar attached, if not, scroll further down this page.
- Grind off the old retaining collar and outer bearing race
- Heat up and chisel off the remains of the inner bearing race
- Slide new bearing onto the shaft
- and slide new retaining collar onto the shaft
Note the old retaining collar has been added to protect the new one from damage
- Drive the collar and bearing home (do not let the old retaining collar become too tight that you cannot remove it
- Fit the half shaft into the axle, ensuring the splines mesh with the differential
- Use the Bearinator (slide hammer) to drive home the new bearing
- Refit the four half shaft clamp plate bolts, torque to 95Nm (Leaf sprung Frontera)
- Refit brake cylinder and metal brake pipe, un clamp rubber brake pipe
- Refit brake shoe assembly,
- Replace drum brake
- Replace road wheel
- Remove axle stands and trolley jack
- Tighten road wheel nut to 120Nm (alloy wheels) 110Nm steel wheels)
- Bleed brakes
If the bearing remains in the housing
Weld a suitable piece of tube onto the inner race of the bearing
and weld that to the Bearinator (or slide hammer)
That should then allow you to extract the bearing (the retaining collar should be a loose fit)
