Guys,
Gerry bought the LH inner spacer for the front wheel bearing which had 11 thousands machined off and the steering wheel which had the addition of a set screw opposite to the loose keyway.
A couple of test runs had the Lynx tracking as it should and NO desire to develop a shimmy after tackling multiple bumps at speed. It appears that there were multiple issues. In summary, alignment, loose LH wheel bearing, sloppy steering wheel, and what I consider the most significant was the loosened U bolts on the front axle.
After the sense of relief following some great runs, the Lynx decided to give me a dose of reality by locking up in fourth gear.
C'est la vie, Peter
