Re: [DML] Re: Setting Front Wheel Bearings

[DANIEL SHANE <daniel.shane@xxxxxxxxxxxxxx>]

[MODERATOR'S NOTE: This is interesting stuff, but future followups that do not have applicability to DeLoreans will be dropped.]

This is How I do it on My Esprits that I have worked
on in the past.

1. Remove the road wheel and check that the brake is
not binding. If necessary, push the pads back to clear
the disc.

2. Remove the hub dust cap, hub nut split pin and
locking ring. Torque the hub nut to 29 Nm (22 lbf.ft)
whilst rotating the hub to centralise the bearings.
Loosen the nut and re-tighten using only hand grip on
the 30 mm socket. Use hand torque only

3. Fit the wheel bolts into the hub and using a
suitable spring balance, measure the force needed to
rotate the hub. Adjust nut tightness as
necessary to achieve the following preload:

With new oil seal 350 - 8759 (0.8 - 1.9 lb)
With used oil seal 50 - 500g (0.1 - 1.1 lb)

4. Using a dial gauge, measure the hub end float.
Maximum = 0.05 mm (0.002 in) Install the lock ring and
split pin, if necessary tightening the hub nut further
by the smallest amount required. Refit dust cap and
road wheel.

5. Apply brakes to restore pad position.

Step 2 is important as it seats the bearing.  If you
do it hand tight only as some recommend then you dont
seat the bearing correctly.  The nut is only hand
tight after it has been torqued and undone !!!

Also Step 4 is Tighten until the Pin goes in NOT
loosen as you will lose your pre-load.
