Re: [DML] Alignment problems?

["tmpintnl" <tobyp@xxxx>]

This is great information for everybody's benefit. The neutral 
position of the front wheels (no toe in) will make the car somewhat 
"twitchy" and directionally unstable. The condition can also cause 
resonant wheel shimmy at certain speeds. The positive toe-in is 
important for these purposes, among many. (As an aside, all modern 
jet aircraft have the engines toed in approximately two degrees for 
the same reasons). The front caster *can* be adjusted by appropriate 
placement of shims in the joint between the front sway bar and the 
lower control arm, although this is not mentioned in the manuals. A 
caster difference between the two front wheels will have a negative 
effect on steering stability as well. As noted, camber is not 
adjustable unless you have custom suspension links that are made to be 
adjustable. The reported alignment should definitely be redone. And, 
(IMHO), the only place to have a good alignment done is at a frame and 
alignment shop rather than a tire store. While there might be good 
tire stores around, they do not usually specialize in "frame issues". 
Just a thought.
