Using a Ball Joint splitter, remove the steering rods
|
Remove the brake calipers -
|
and tie securely out of the way
|
The Free Wheeling Hubs have a small screw which you need to undo
|
Inside there is a thin nylon strip which holds it in place. Using a narrow screwdriver you can hook this out -
|
and the cap will come away
|
TUsing Circlip pliers, remove the circlip from the end of the half shaft
|
Loosening the driveing Member bolts can be tricky, we used a bar to hold the hub stationary and to give extra leverage
|
with all 5 bolts remove the drive member comes away
|
This exposes the locknuts and lock washer
|
With a hub spanner, remove the first lock nut, the lock washer and the second lock nut
|
The hub assembly will now come away
|
Revealing the stub axle assembly
|
Undo the 6 bolts holding this in place and remove
|
Next loosen and remove the swivel housing bolts from the end of the axle
|
Let the residue of axle oil drain away -
|
and clean up the surface ready for fitting a new gasket
|
Strip down the swivel housings and inspest all the bearings, pins, surfaces and oil seals
|
Refit the pins, with new gaskets, shims and bearings and tighten
|
Check the swivel load. With the swivel housing, using a spring balance you can check the force required to move the steering arm.
|
Clean up the surfaces
|
| IMPORTANT: If the bearing pre-load is OK it should take between 3.6kg and 4.5kg of force (36N to 45N) to move the steering arm. the bearing pre-load is adjusted by varying the thickness of the SHIMS on the upper bearing pin. If it takes MORE than 4.5 kg to move the arm then you will need to fit THICKER shims, if it takes LESS than 3.6kg of force you will need THINNER shims. If you can get it to around 4kg wit all the bolts tightened to the correct torque thatwill be just right.
TIP: If you can, see if you can buy a selection of shims on a sale-or-return basis from your parts dealer. There's nothing more frustrating than finding you need a different shim to the ones you've already got - and your vehicle is out of action so you cannot drive to get another one! Similarly with your oil seals and bearings, to buy everything would cost a fortune, but if you find you need it and you haven't got it is very annoying.
|
Fit a new Oil Seal inside the stub assembly
|
Fit a new Swivel Oil Seal
|
We decided to fit new Rubber Giters from BAILCAST (see separate review here)
|
The gaiters are spilt, allowing you to fit the without stripping dow the hubs and glue them together once in place. But as we already had the hubs off we glued the ends together prior to fitting
|
While the glue dried, we fitted a new gasket -
|
then stretched the gaiters over the stub assembly
|
The Gaiters are very pliable and easily fitted into place
|
Once in position fit a new swivel seal retaining plate -
|
and bolt down
|
Apply the gaiter clamp (supplied) you could use a jubilee clip if preferred
|
All new parts fitted and new gasket in place
|
Re-fit Swivel Housing and half shaft. When re-assembling the stub assemblies you must use Nut locking Compound on all bolts
|
Position the stub assembly over the shaft and secure with 6 bolts.
|
Cleaning up the hub assembly and inspecting the brake discs
|
New bearing fitted in place and packed with grease
|
New bearing fitted to the rear of the hub assembly - again packed with grease
|
New Oil seal fitted and drifted firmly into place (it's a tight fit)
|
Hub assembly re-fitted
|
Lock nuts tightened, lock washer replaced and secured, and the second lock nut refitted and tightened.
|
At this point you are recommended to check the halfshaft endfloat. using a dial guage.
Bearing in mind that most people will not posess such a device, the following procedure will suffice:
Tighten the locknut with a hub spanner, at the same time spin the hub assembly, keep tightening the locknut until you can feel it getting harder to spin the hub. At this point back it off one quarter of a turn. Don't tighten it so much that it's very hard to turn the hub but you should be able to feel it getting harder as you tighten the nut.

We fitted a new Driving Member and gasket (in place of the Free Wheeling Hubs we removed)
|
Refit the shims and circlip into the groove on the end of the half shaft and refit hub cap
|
Refit Brake Calipers and new brake pads if required
