Gene,

In my case, I'd almost had an accident approaching Branson, MO. I dropped
the right middle and rear wheels off of a high pavement shoulder during a
"starboard hard as possible" turn, bending the rear arm out about 3/4". I
was so rattled by the experience that I didn't notice the damage until the
ferry arrived in Alaska. After hunting all over Alaska for someone, or
some way to fix it, we arrived at Elmendorf AFB at Anchorage. There, the
power post in the campground was protected by a 6" steel pipe buried down
into the permafrost and filled with concrete.

I parked one 6-ton bottle jack height away from that post. With the air
bag deflated for that wheel (4-bag system), I put the jack between the post
and the spindle and pumped away. After sliding the coach a few inches in
the gravel, the arm stayed where I wanted it. When I finally got to Jim
Bounds' 8-10 months later, that arm was right.

But the middle arm was still bent slightly out. Since Jim had no
permafrost in Orlando, not to mention a steel post, we had to devise
another method -- he'd never bent one in before. We parked the coach in
the doorway of his concrete block shop. A 4x4 between the frame and the
door casing on the left side kept the coach from sliding when we put the
port-a-power between the spindle and the door casing on the right side.
Just a few pumps and that was fixed.

If your arm is bent only in or out, only toe should be affected. In that
case, the tread on the tire should be worn to a "sawtooth", which you can
feel by running your hand back and forth across the tire tread. If the
"tooth" is high on the inside of the tire, you've got too much positive toe
(the rubber's "pushed up" to the inside). If the high side is out, there's
too much negative (pointing out) toe.

No photos -- I wasn't planning a seminar. :-)

Severe wear on the inside sounds more like negative camber (wheel leaning
in at the top) to me. That will probably require a "Sirum Arm" -- a long
2"-3" pipe welded to an old wheel rim to use as a lever. You can, as
suggested, shim the bogie to correct that -- but ONLY if BOTH wheels are
equally incorrect.

HTH,

Ken H.
