Technical Tips/Discussions: by Roy Cail
Will a loose ball in the front wishbone at the transmission cause a
shimmy?
Yes, this could be one of the issues causing a car to shimmy. A loose
ball in the front wishbone can be one of the causes of front shimmy. The front
end caster ( 5 degrees) is dependent on the exact position of the front radius
ball. Make sure you have all the correct pieces to mount the radius ball to the
bottom of the flywheel housing. It should consist of an upper and lower cap,
two spacers that fit through the mounting holes in the lower cap, two springs
and two castle nuts. If the assembly is correct and the ball does not fit
tight, purchase or make a shim out of a thin fender washer, pounded to fit
around the top half of the radius ball and reinstall the cap assembly. Then
measure the front end caster. Also make sure the tie rod balls are round and
the drag link ends are screwed in tight enough -- check Les Andrews Mechanics
Handbook for specific settings. Toe-in
should be 1/16" to 1/8". Also make sure the mounting bolts for the
steering gear box are very tight. Worn king pin and/or bushings can contribute
as well. All these things relate to front end shimmy. The most over looked and
cause is incorrect front end caster adjustment. This is determined by the
position of the radius rod ball. |
