Question about RR axles

[nickyill]

I believe the Brits are quite fond of those bushings...I've never known anyone who tried them...

Depends whose they are

The SP ones take all the cr&p Aus can throw at them, along with the former USSR, Africa an Europe. And a warrantee like that backs up a good product.

You guys need to catch up bit on the rest of the world :wings:

We know they are out there, just don't seem to be very prevalent here. Cost-wise they definitely are much cheaper - I have heard that getting them installed at the proper angles can be tricky, but we all own Rovers - so what repair job isn't a pain in the ***!

What material are these "better" caster correction bushing made from? If it is poly, you will typically lose articulation (stiffer material) and have increased noise (lower attenuation over natural rubber).Using other brands of the same concept, these units tend to self destruct quickly. Just by nature of the design, you are removing compression material from one side of a fixed diameter bushing.


Do you have any information on these? long-term testing, etc. I would be curious to read more.

Thanks

OK, well that's not what I expected - I had believed that the braking system was the same over there as here, at least for commonality's sake, but mainly because Discoverys are seen as more prestigious than in the UK, and so seemed more likely to have the higher spec equipment. I have an early 200Tdi front axle (1991, I think), and that's dual circuit, so it seems bizarre that the later US models were down graded with single circuit...

200TDI era Discoverys (the REAL Disco 1s) were never sold in the USA. They started selling them when the 300TDI (Disco 1a ??) came out in 1994.

Depends on whether they are cold cast or hot pored

In the bad old days we had Polybush. Hot poured so not and elastomer but a plastomer. They were under the mistaken idea that bushes needed to be harder than rubber. This doesn't work.

In reality bushes deteriorate due to a lack of flex. So an elastomer is what is needed. Fulcrum Suspensions down under came up with a rather clever idea that worked very well.

I have been using, testing and writing about this stuff for the best part of ten years, but the guy you need to talk to is a man called Graham Scudamore-Smith; he owns Fulcrum, who make SuperPro (and do a shed load of other stuff) and knows more about decent 4x4 suspension (and cars) than most people.

If you want I will forward his details....

By the way SP's bushes allow you to get the max out of the standard system through rather clever design and lubrication

As for the castor correction stuff - I could tell you shed loads but once again Graham is the man.
