Thread: Lower Control arms

Let me know how the poly bushes get on...
Both changes to ride and keep an eye on the chassis mount point (after some severe off-roading and say 10,000km).

I'm keen to see what influence these elastomer based bushes have in such a high flex environment.

Will do Tombie, I'm also interested how they go. Keep an eye on chassis mount point?? I'm a bit confused on that point, do you reckon they would be to hard on the chassis causing cracking?

I've always been impressed with Super Pro.
In this application replacing a Hydrolastic bush I'm concerned there may be some additional stress on the arm and mount as the range of motion with factory bushes is significant.

Tombie, does the factory bush allow movement in the other axis, other than just rotation around the pin? Is that like a knuckle joint in that case, albeit with less range and perhaps damped?

Then the theory is that a stiffer elastomer alternative could transfer that load to the mounting (chassis).

If I'm anywhere close to right, I can't see how the factory bush actually works

Mine has way to much movement in the other axis at the moment, therefore the clunk I get when hitting any sharp edged objects. Here's a good video of it, not mine, but I shot a similar vid that showed the same! [ame]http://youtu.be/0vD1CkzTGJA[/ame]

To understand how they move - Look under your vehicle (from safely away from being squashed ) and ask someone to raise to full height and then lower to minimum and watch the fore and aft movement that the bush caters for...

These are the style of bush..



As you can see there is room for fore and aft plus some off axis movement.

The centre of the bush is usually filled with oil...

Make sure to keep us posted on how they go once installed and the long term durability.

I had enough on my 06 disco they flogged out in about 70 thou kms. Much nicer ride with originals
