--- Quote from: "TheBlueySilverThing" ---errm steve, the rear is effectavly 3 link :roll:
the a-frame ball joint is the 3rd link
:roll:
--- End quote ---
on a normal set up the a frame is solid to a point which partly holds the axle in place.
mail 4x4 order do one that gives more movement but with a 3 link system only on the back it not so easy to explain.
for a start the rear props needs to have massive slide to cope.
big lift is need to allow such movement under neath.
tyre size is a other problem because they will hit the inner arch before maxium movement.
at the centre is of the a frame joint is a type of cv joint which allow alot more movement but is stopped at a point on each slide so u dont get wheel skimmer or rear steer .
at the slide of the a frame joint is a piovet to allow drop on the axle. wish had took some photos of it in action underneath.
with the cv bit u get this much movement.
wheels level is at 12 olock and 6 oclock
which moves max movement one is at 10ish on the clock and 4ish on the clock.
the guy who i know uses this system has work out the angles in degrees of movement yet.
he also has bottem dislote hats on aswell on the rear.
he has 109 on a range rover chassais wided body.i say 8 inch lift and 1100r16 xcl tyres on the first time i was this conversion

you mean the qt one that they sell. which has the same joint but with a slightly bigger degree of movement,,,9 degrees....trying looking a little depper rather than believing your mates guff!! pmsl!

he had it on the ramp at gaydon 2005 for all to see.
okay qt do sell them just saw it on mail order 4x4 in lro that all

Its still a 3 link system same as standard.
The only difference being the maximum amount of movement before the joint binds.
As for rear steer, a different A frame joint won't stop that as its due to the nature of the limited arc the trailing arms move through. Easiest solution is to make the trailing arms longer and move the chassis mounts further forward.

qt make em..its stamped on the side.....
sorry if it seems like im constantly flaming you but you can buy the joint from paddocks for about 40 quid....
bullfrog also does one....and you dont need a modifired rear prop unless your lift has moved it towards its limit
