The M16 clamp bolt set is a direct replacement for the M12 set, and it is recommended that at the time of
fitting, the hub is removed from the bearing and the condition of the hub spigot carefully examined. If any signs
of bearing inner race movement on the hub are evident, the hub and bearing should be renewed and assem-
bled with the new bolt set.
To Replace Wheel Bearing
1. Release the two fixing bolts, and remove the brake caliper from the hub carrier. Support clear of the
brake disc without straining the flexible hose. Withdraw the brake disc from the hub.
2. Release the four fixing screws, and remove the lower swivel joint from the hub carrier.
3.. Release the two bolts, and taking care to retain the camber adjustment shim plates, separate the steering
arm from the hub carrier. Remove the hub carrier to a bench.
4. Remove the hub clamp bolt and washers, noting that LH hub M12 bolts are LH thread (M16 bolts are
RH thread for both sides), and press the hub out of the bearing. If necessary, use a puller to remove the
inner race from the hub spigot.
5. Remove both circlips from the hub carrier, and press out the bearing.
6. Before fitting the new bearing, clean any corrosion from the bearing bore outside of the circlip grooves,
and fit one circlip into position. Heat the hub carrier in an oven to 90°C for at least 20 minutes before
pressing the bearing assembly into the carrier to abut the fitted circlip. Retain by fitting the second circlip.
7. Supporting the inner bearing race, press the hub fully into the bearing. It is recommended to fit the M16
clamp bolt set, but if the original M12 bolt is to be re-fitted, fit the bolt from the outside inwards, with - RH
thread on RH side, LH thread on LH side. M16 bolts are not handed, and should be fitted from the
inside outwards with a plain washer and the bearing dust shield beneath the bolt head, as shown. The
smaller of the two special stepped washers locates against the hub, and the larger against the bearing.
