Understanding Polybushes
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? |
bolts
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.

Poly Bush Source
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.
Regards to all. |

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.

sam i thought the rally design crush tubes were too short?
