Once you have this issue resolved, it is well worth fitting a gaiter to the rebound spring to keep road dirt and grit off your King Pin. It will extend the life of the bushes and King Pins substantially. There is a thread on TM on this. You can make the gaiters out of an off cut of Mohair hood material (as per DaveW), by cutting up an old inner tube or by using a short length of car heater trunking.
There is a page on
Morganatica about gaiters - the page includes top and bottom gaiters. The bottom ones are the most important - you will find a design sketch etc there.
