I've just done one side on mine found the bolt heads had become quite badly corroded on the king pins swivel seal and half shaft retaining bolts probably due to brake dust /mud etc. Managed to get everything undone but several bolts got destroyed on the way splashed out and replaced all with stainless ! Just be warned. on the subject of sealant I used a smear of instant gasget any type will do. Good Luck
Swivel seal bolts M6 x 1 x 10mm 16 in number
King Pin Bolts M8 x 1 x 20mm 16 in number
Drive Shaft bolts M10 x 1.25 x 25mm 8 in number
Thats the quantity to do both sides
if you are only changing the kingpin bearings you DON'T need to dismantle the hub.
Remove vacuum pipes, remove caliper and hang out of way, no need to disconnect brake pipe.
Remove large seal, (ring of bolts).
Remove kingpins, eight bolts, four top, four bottom.
Draw off complete hub and half shaft assembly.
ALWAYS replace small internal oil seal.
Knock out bearing tracks, gently with a small cold chisel, easy but fiddly.
Clean carefully.
knock in new tracks, (the right way round !), careful.
fit bearings, LOTS of grease.
replace small seal.
put everything back together.
Job done, half an hour each side !!!!!!
I ALWAYS use waterproof grease on the king pin bearings and before any clever dick says all grease is waterproof, its not it can emulsify with water. Water pump or underwater grease is easily obtainable and completely solves the problem of water causing the kingpin bearings to rust.
Only use the correct driveshaft coupling grease on the couplings though because it is high pressure grease and is also anti fling.
If you are an engineer then a grease nipple can just be squeezed in but you do need to know what you are doing.
Hope thats a bit clearer than mud
all the best Bryan D
