Which bolts to grease
What suspension bolts do I need to grease, I'm using polybushes. I'm assuming as they are self lubricating they don't need it, but would it be good
on the bolt to stop any rusting of the inner tube.
And shock bolts????

Probably a good idea to use coppergrease or some other anti-sieze compound on the suspension bolts (all of them including the shock bolts) to stop any
rust or siezing. The sleeves should not be turning around the bolts, though

There are different types of plastic that can be used for bushes, the most common are polyurethane (PU), and some of the polyacetal family (POM).
PU is usually made in bright colours like red, yellow, and purple, and you can dig your thumb nail into it, even the harder grades.
POM is usually natural (sort of translucent white), but sometimes black. It's very hard, but you could pare a bit off with a knife.
PU is a good replacement for rubber bushes, as it comes in various hardnesses, and is virtually indestructible. It does, however, require lubrication.
In the case of suspension bushes, the lubricant should be moly or graphite grease, and applied ONLY to the outside of the steel/stainless steel crush
tube, and the bore and flange faces of the PU bush. The bushes will need to be dismantled ocassionally, washed in white spirit, greased, and
reassembled.
Acetal is very rigid, and would normally only be used for bushes in competition as they give a very precise, but harsh ride. They too are virtually
indestructible, and the H-TF (Teflon fibre reinforced) variety don't require any lubrication.
I use a lot of both types of plastic, but prefer acetal, as it machines so well, and as it isn't lubricated, doesn't attract dirt. PU can be a
bugger to turn unless you keep tooling solely for it.
