pin bolts, install bolts and tighten to 65 Nm (48 lbf.ft).
34. NOTE: Swivel housing oil seal and axle should not be
148 of 1212
34. NOTE: Swivel housing oil seal and axle should not be
fitted.
Attach a spring balance to track rod ball joint bore and pull
balance to determine effort required to turn swivel pin
housing. Resistance, once initial inertia has been overcome,
should be 1.16 to 1.46 kg. Adjust by removing or adding
shims to top swivel pin.
35. When setting is correct remove top swivel bolts, apply
sealant, Part No. STC 50552 to threads of bolts. Refit bolts
and tighten to 65 Nm (48 lbf.ft), and bend over lock tabs.

Or,

Support on axle stands under chassis
remove front wheels,
disconnect track rods
now 'feel' pressure required to turn hub, it should feel reasonable resistance, without hard spots, grunching or tight spots
if its too loose, very easily moved, trolley jack and block of wood under lower swivel pin and just take weight of hub.
remove top two bolts and remove the pin, steadying hub in place, remove smallest shim, refit top pin and torque up.
Remove pressure from jack
Feel hub rotation again, if too slack repeat above and remove another shim, if only big shims are left, add back smaller shims.

Obviously a supply of shims and a vernier caliper help, as does a helper. The jack keeps the hub loaded and stops the grease running out from the seal, a helper can steady the hub to keep the top pin bearing line centralised.

I find if I can rotate the hub with one hand fully built up, it equates to the factory set up without the wiper seals etc in place. I can do both sides in about an hour, on the drive with a trolley jack and air wrench.

Good luck

Try 2 packs of 1 shot grease, I use it in the front of my 100" bitsa running classic range rover axles, so should work happily in a 200 / 300 Defender, better lube in hot climate I would guess also.

Standard fit in all Puma's I think also.

Best of luck, let us know how you get on.

Most people use an oil called Morey's Heavy duty stabilizer in their hubs here ... but if that is what the guard requires then that is what it will be Knickers , not the best thing in the world ... but right next to the best thing in the world

Just in the process of re-doing my swivels and replacing the balls to cure an the wobbly steering but I have a query on the torque vales for the upper and lower swivel pin bolts?

BM52's instructions earlier say top bolts 65nm and lower bolts 25nm which matches the values in the Haynes manual and looking at the bolt sizes, feels about right. Looking at my TD5 workshop manual, there is no info on rebuilding the swivels apart from the 300tdi supplementary section. This specifies 78nm for both upper and lower bolts. Can someone kindly confirm for me?

It's a 2005 Td5 110.

Many thanks,
