Challenge 90 Rebuild / Rear suspension arms
The increased wheelbase on the vehicle had been obtained by moving the spring mounts backwards, this in turn meant that the suspension arms would need to be altered.
The lower links are simple, being a longer version of our existing heavy duty cranked radius arms.
The upper links on the axle take the form of an a-frame with a ball joint assembly to locate the axle. Many ideas were discussed relating to manufacturing a replacement item, possibly using a rose joint or Johnny joint to connect the axle.
Eventually, the KISS principle won through, and a simple spacer was prototyped which moved the existing ball joint assembly backwards to the correct location.
New Polybush bushes were installed and the a-frame assembly was fitted to the vehicle.
The holes which connect the ball joint to the spacer were drilled at such an angle that the ball joint would sit more squarely on the axle, reducing the chances of binding under long travel situations. Even at full droop, the ball joint retains plenty of movement.
