Understanding Polybushes

[aerosam]

Hi guys,

I'm expecting the polybushes for my wishbones to arrive today (fingers crossed) and I've just realised I don't really know much about them, as I have never used them before.

So I really have 2 questions:

1. What is the correct method of assembly?

2. Do they need any lubrication, grease/oil?

Thanks!

Sam

Should be a push fit and should come with some greasey stuff although the insert may prove a tad awkward to get in but no drama really... .honest

Thanks guys,

the bushes did indeed arrive today and I was able to fit them without much drama at all! The bush halves went in by hand, and I just had to use a G-clamp to press fit the crush tubes.

I have trial fitted the drivers side wishbones with the upright and it all fits and moves really nicely! I'm so chuffed!

One thing, I need to get the correct bolts for the wishbones, I'm thinking M12 x 70?

70mm sounds about right as u would have the bracket width + 2 washers +the thickness of the nut + couple threads out the end of the nut.Just remember u need 8.8 tensile strength bolts,buy BZP(bright zinc plate) also.

Please help. Where do you English chappies get your polybushes? I tried sourcing them locally today & they look like costing me more than the rest of the project.

You could always make your own, UHMWPE is a hard plastic and good for bushes and machines easily,a piece of 19 mm steel bar and off you go.

Thanks fellas. 3gecomponents look like the business but airfreight to NZ is a bit horrendous, maybe good old fashioned sea freight will be cheaper. Rally design don't appear to have an e-mail address.
