With some of the recent steering threads being seen, a very common problem with landrover steering is the result of the combined wear and lost motion in the many steering links, ball joints, drop arm splines etc.. Any movement of the steering relay in the chassis will cause dramatic free play at the wheel.
As the relay should fit tightly in the chassis it needs to be shimmed and tightly pressed into the front chassis xmember. This of course can make future removal of the relay a task.
When I fitted my new chassis, I found the relay tube in the chassis left a large clearance all round the relay itself. Shimming is rather crude and as I didnt wish to have to press the relay into the chassis I made up a collar that bolts to the 4 1/4 UNF bolt holes on the underside of the chassis, with the base of the relay passing tightly through it.. This elliminates the need to shim, gives an accurate, solid and fixed location for the relay.
The result is a very pleasent and precise steering, running on 9.00x16 crossplies
