whats this king pin shim preload marlarky?

Hey guys

i got leaky hubs, wobbly wheel bearings and my mechanic is flat out like a lizard drinking.


so i want to give it a shot, armed myself with work shop manuals, poured over many internet threads and stacked the shed fridge full of beer. all i gotta is order the seals and the bearings.

so i got my head around it, or so i thought. but everyone talks of king pins, shims, and preloads. i know the shims set the preload. (i hope im right on that assumption)

my question is this, when i replace the king pins do i just reuse the old shims or do i need new ones, and how do i work out if i have to add more and swap to thinner ones to get the right preload. am i going to be right, with just swapping my shims from the old bearings to the new one?

and the next question. considering im not a shUt hot mechanic and im not a completely mechanically clueless, how long should i allow to strip and rebuild the hubs and do the bearings ? 1 day, 2 days a week ? a month or should i just set fire to it and buy a vespa? :P

lol cheers guys

that was the the thread i was pinning my hope on lol i must of missed the part on preload, ill give it a re read :)

Correct. The only way to adjust the pre-load is by putting in different thickness shims. So, to do this correctly, you'll likely need several different sizes on hand before you start. Patrolapart has some sizes, but I ordered four (2 per side - top and bottom, 2 sides) of about four different thicknesses from http://partsouq.com (you could also check out http://nissan.epc-data.com). The shims from partsouq were pretty cheap - but you do have to factor in shipping cost and time for delivery.

Don't forget that you should put identical sized shims both top and bottom - this centres the axle vertically and will give your axle seals a better lifespan.

The king pin bearings run moly grease do to the limited movment these bearings do and the load they are under.
