	Hello chaps, I am in need of some guidance once again. I am going to be pressing 16 2pc polyurethane bushes into some Wishbones soon and I am looking for a suitable grease to help press them in. The bushes are Duraflex 95 shore A grade (if that means anything to anyone, because it doesn’t me!) which I think makes them the stiffer bushes. Usually, is just slap any old stuff on there and whack them in, but I am conscious of using a grease that will breakdown the bush, if thats even possible. Does anyone have any “bush friendly lubricant” they could recommend please? Cheers!

	Normally, white lithium grease is what most of the bush suppliers supply.

	Don't forget to also grease the steel sleeve, unless you like the squeak and excessive wear :-)

	Thanks for the input here guys. I contacted the supplier and was told anything apart from fairly liquid (didn’t realise that was a done thing) would be absolutely fine. Thanks for the help again.

	My understanding was that you don't grease the outside of a polybush (if it's in suspension anyway). The bush/sleeve acts like a bearing, with the outer part remaining still in the wishbone and the sleeve spinning around inside it. I'm not sure if greasing the outside would do any harm though, so it's probably not critical. I use silicone grease, but I've seen white lithium and copperslip used (although I'm not sure if the copperslip is a different variety from regular stuff).

	It turns out my home made wishbones had crush tubes that were 1mm too small, so the bush would push in fine, as would the crush tube until it was half way in, then the other half way it would push the bush out the other side. New bush tubes 1mm lever and fingers crossed, the bush won’t push out the other side! Just got to wed then all up now.
