Trailmaster vs. Black Raptor

No worries, I'd not even opened the bag so didn't know myself lol

Personally I hate doing bushes. Make sure you orientate those new ones correctly, being castor corrected they only fit correctly in one place.

I'd say fitting that single poly one might be fun..... as can getting the old ones out. When I did my front arms on my Land Rover, I thought I'd try the drilling the rubber out. Resorted to the press in the end. One needed about 12 tonnes of pressure to pop it out.

That said, smaller car like bushes I've done on a vice before. Still not fun though.

The above method only works if you're installing poly bushes, because they are a super easy DIY install, no special tools required!

That is interesting to read as I got these CORRECTION BUSHES with my lift kit and I was wondering if screwed rod, nut bolts and spacers would be enough to get them in. Just a quick squeeze through the bag didn't feel like any give in them.

Soeley I can only speak for the power flex bushes that I bought as a full car kit for my Z3, but all of the poly bushes came in split halves that are assembled VERY easily by hand with some silicone lubricant (usually provided) you then push the steel bush through the centre again by hand. Looks like you caster correction bushes are one piece!

There's different hardness ratings of poly bushes, I think the unit of measurement for this is defined in 'SHORE'? In terms of the powerflex range, the black bushes are the firmest - purple are the most comparable to a rubber OE bush. But the assembly method is exactly the same

Installation wise, they normally supply a little sachet of silicone lube :silly: either a bench vice job, or threaded bar and washers will be needed to install those.

Check out this videos which illustrates the removal method that I used for the OE bush. (chain drill & hacksaw) other methods like an oscillating multi tool & hole saw would work great too.

Remember the lube is not just for fitment. It is integral on how a poly bush works, as the centre insert is held tight when bolted down and the insert should be rotating inside the polly. Rubber bushes are bonded and rely on the stretching/compressing of the rubber through a twisting action.

They are castor correction bushes.... You would hope that the centre's don't rotate, you would have variable castor angle...... :laugh: :laugh: :laugh:

+2 I had some powerflex rear control arm bushes on the Z3 that had a knurled centre pin designed to grip and not rotate.

All depends on the type/style and function of the bush I guess.
