Bill, as a "seasoned" mechanic, I certainly expect that you should know the
mechanic's creedo: Assume Nothing. I am with Roy on this one.

Re: A case of death wobble today
 

If a seasoned mechanic knows that a certain symptom commonly has
a serious (expensive or dangerous) underlying cause, the good
mechanic will always search for the possible/probable cause
rather than just apply a band aid fix. For said seasoned mechanic
to suggest to a neophyte that the fix is easy with a band aid is
rubbish. For something as serious as Death Wobble, it is highly
undethical to not point out how close to the edge the vehicle MAY
be.

Most of the newbys that read or post on RAMJ+W have read or heard
about Death Wobble, they think it is an interesting name, and
laugh it off. Anyone that has experienced it on a ride from 60mph
to 10 or 15 mph has a different view of it.

I have personally spent way to much time chasing down various
thumps, bumps, and loose joints that only manifested themselves
in very strange directions or on seemingly unrelated parts. They
can be very hard to find until it almost falls apart in your
hand. I'm a big boy and have done this before. But newbys expect
and need more than the one liner.

If your original advice had been to "replace the stabilzier but
be sure to check for usual culprits of loose tie rod ends, ball
joints, alignment, and tire balance" we would not be having this
discussion. If you want to come off as an expert, give out advice
that won't get someone killed down the line.

A steering stablizier on the drag link doesn't do all that much
good. DW is where the two tires start oscillating between them
selves, the tie rod is the connecting link.
