Re: A case of death wobble today
Hi Mike,
They change that angle for sure and head it straight for the
transfer. I'd say for four thousand bucks the tubes will be rewelded at
the proper perch and castor angles. http://www.dynatrac.com/rock60.htm

Re: A case of death wobble today
Sorry Bill, until YOU take reponsibilty for YOUR actions, you
will have to simmer in your own stew. And you appear to be
simmering pretty good.
I used to have the real address until the Sven virus hit me with
4mb of crap per HOUR. Which of course took my e-mail down pretty
solid after 9 years on the same name. So I will NEVER put my
e-mail address in a public forum again. Sign of the times I guess. :(
I'd suggest you wait for Terry Jeffry (the original poster) has
his front end checked out. If an INDEPENDENT mechanic/shop checks
out the massive amount of work that was done on the OP's front
end and the ONLY thing that is wrong is the stabilzer, I will
gladly appolgize for aggrevating you so much. And then I will
repeat my comment that a stabilzer just masks the underlying
problem.
Cheers.

Re: A case of death wobble today
Sorry Bill, until YOU take reponsibilty for YOUR actions, you
will have to simmer in your own stew. And you appear to be
simmering pretty good.
I used to have the real address until the Sven virus hit me with
4mb of crap per HOUR. Which of course took my e-mail down pretty
solid after 9 years on the same name. So I will NEVER put my
e-mail address in a public forum again. Sign of the times I guess. :(
I'd suggest you wait for Terry Jeffry (the original poster) has
his front end checked out. If an INDEPENDENT mechanic/shop checks
out the massive amount of work that was done on the OP's front
end and the ONLY thing that is wrong is the stabilzer, I will
gladly appolgize for aggrevating you so much. And then I will
repeat my comment that a stabilzer just masks the underlying
problem.
Cheers.
