We fitted the front wishbones
and shocks to the chassis. The nolathane bushes were lubricated
using a special polyurethane grease known locally as 'goop'. The
wishbones were a tight fit, but we got there. Fitting the ball joints
was a new experience. Apparently, the shaft and matching bore of
the uprights are tapered. It is called a morse taper, and the idea
is that the ball joint shaft will bind in the upright from friction.
This is pretty effective, and is the reason a special splitter is
needed to separate a ball joint from it's upright. Anyway, the parts
are all in place and torqued up (9.7 kg/m according to the manual),
and the hubs and discs are attached, and looking pretty good.

| Here
is the front from the left side. The Westfield manual recommends tightening
the suspension bolts until they just grip, but to avoid binding the
components. This is difficult to judge, as the nyloc nuts are quite
tight to turn once they bite, and the suspension seems fairly stiff,
even though I deliberately avoided over-tightening. Still, with 540
+ kg it will probably move more freely. |

The rear suspension was
a little more difficult to fit (read had to use the BIG hammer).
Mostly this was due to the substantial weight of the diff which
had to be suspended from the frame to allow fitting. I found the
best way was to suspend the axle/diff fairly high and fit the lower
trailing arms at the axle end, then the chassis end.
Then I lowered the diff
and fitted the upper trailing arms, axle end then chassis end. The
axle end uses 120mm bolts which pass through the shocks, and then
chassis brackets and trailing arms. The bolts only need to be just
over 100mm in length, so there is almost 20mm of thread sticking
out towards the hub. I don't know why Westfield did this. I'll probably
cut 15mm off.

We bought a Dial guage and magnetic stand, and aligned the diff ourselves using the workshop manual. The cost of the instruments was $90, which is a lot cheaper than it would have cost to have the diff professionally set up. Anyway, as mentioned before, it is probably pretty worn, and will have to be replaced, so no point in throwing money at it, although I have no problem with spending money on tools. You can't spend too much on tools, books or education.
