Thought I had heard tires should be toed out 1/8.
Bill,
I should have been more specific and just said +1/8 toe. It's "out",
not "in".

Hi Arch,
All I know is My 74 GMC drives straight as an arrow and
the rear tires are toed in at the tops alot. Sometimes
I think it looks like their leaning in so far the rear
axles must be bent....but it sure drives nice..no
wiggle wobble at all.

Tom,

Thanks for posting that article, it does a good job at explaining Camber,
Caster & Toe.

I will have to say though, that I tend to lean toward 1/8" toe out. I
tried toe in and it made the coach feel like it was sitting on top of a
basket ball! The toe out setting seems to make the steering more natural.

I do put the Camber right on and also give her as much caster as the law
allows or at least the adjustments will afford.

I will also tell you it is pretty interesting setting the toe on a coach
with a little play in a part. You can kick the tire and wack out the toe.
I end up kicking the tires several times to find the "average" in the pay
and set the toe at that point. Of course, I recomend making sure all the
front end components are checked and report good but it seems that some
coaches have some play on the machine even after a thorough check.

Next time you're down, take some time and come by & I'll show you what I mean.

Just a thought, may not mean anything, I have measured the ride height
sitting on my driveway a couple of times and I always come up with 3/4
inch higher on passenger side.I'm sure it has intentionally been set
this way. could this be to compensate for crown in road? or what

could this be to compensate for crown in road

Emery, I assume it was set 3/4 in high on pass side as it it would
seem unlikely that it could get that way by chance. Not saying its
right. As for crown in road, I thought alignment was set to compensate
for this also. Average I guess. Since my steering went south when I
changed tires(size and pressure)also relay arm, I'm wondering if the
difference in tire height 8.75 versus 9.50 is enough to affect anything.
Must admit I am shying away from changing ride height. Am seriously
considering putting old tires back on to see if that changes anything.
Will try new steering box first. Always appreciate your imput and
knowledge.
