Anti-wrap bars - my solution

Why even have bushings at the axle?

cos its cheaper and easier to replace a set of bushes once a year than potentially suffer stress fractures from having solid mounting points.

It's an ongoing experiment - Rover use bushes in their arms on coilers, so we did the same - to be fair when the bushes were in good nick it worked fine, hopefully the polybushes will last a bit longer.

Given that they are bushed at the chassis end and properly fabbed at the axle end they shouldn't suffer any cracks.

I'd vote for keeping bushes Dan - you know the "less than perfect" road surfaces John drives on - I would have thought that having the additional rubberware in the assembly would give a longer lifespan as loads are shared, its an interesting long term test though

superpro if/when the polys die John? Im dead impressed with the beasting they seem to put up with

what size heims are they, there might be some spares in stores?

[FridgeFreezer]

"Additional rubberware" eh?

I'll see how the polybushes go, at least they'll be easier to change if they do die. I found my spare heims so all's well there thanks.

Fridge, i do like your 109

Most of the yank ones use hiems at the axle ends, almost none of them use bushes.

I think heims at the axle end would encourage it to skew sideways rather than react against the load though, with the heim on the shackle as well it would be able to twist the assembly off to the left or right rather than staying in a straight line and taking the load. That's why I have a box of spare heims, originally we planned to do it with heims all round, then I thought it might make it kinda floppy

Quoting Fridge Freezer  from the Leaf makes thread, about an update on this subject and trying to remain on topic:

Well for the last 5 years it's hardly been driven so can't really comment... but I reckon the front binds up a bit but the rear works a treat due to being the other way round and having much longer links (very close to the length of a leaf).

I'm still mulling solutions for the front but just need to get the damn truck up & running again before starting more projects! End quote.

What about bringing the  torque arm for the front axle to the front ? Tie it to a new crossmember right behind the bumper. Too many tie rods in the way ?

There are basically 2 options: a Ladder bar (like fridgefreezer) or a tractionbar (like Soren has on his series 1 landrover). From a geometry point of view, a traction bar is a better solution, as a traction bar will fight the axle movement, as it forces the axle to rotate around an arc, which is not its natural movement.

This is quite well explained here (albeit on toyot landcruiser):

We just used an old radius arm and a johnny joint.  Cheap, quick and easy.  Works great.

Red 90 - this looks a great idea, did you do front axle as well? any more pics of how the shackle was attached to cross member ?
