In light of the discussions that were going on here last week, I thought
that I would relate my experiences with t he new 1 ton front end. Mine
was installed several months ago and after it was done, while I liked
the improved braking and tracking, I had MASSIVE torque steer problems.
First, min steering box had a bunch of vertical play on the input shaft,
so we replaced the steering box with a BRAND NEW (not rebuilt, NOS, but
brand-spanking-new) box. That helped (a little), but my coach would
still "jump" about 4" to the left when accelerating, the tires would
break loose and squeal and I would get wheel hop crossing an
intersection with a crowned road.
Back to Manny's (could NOT make it up his hill, large clouds of tire
smoke). Manny VERY carefully made sure that the steering box was
properly centered, but more importantly, he replaced the tie rod ends
and mad sure that the tie-rod end clamps were VERY tight.
On our last outing (49ers Rally at Casa de Fruta), I had a long stretch
of road all to myself, so I did a WOT acceleration from dead start with
my hands OFF the steering wheel, the coach did nothing but go straight.
In the 10 years that I have owned this coach, this is the very first
time that I have had zero torque steer!
The moral of the story is....while the 1 ton front end may be (and
probably is) the best thing since bottled beer, IF you have other
pre-existing conditions (like bad tie-rod ends) it will exacerbate the
problems. It should not be looked at as and end in itself, but as a
part of whole front end assembly. If there are other issues, it WILL
help you find them!
As I said, I always had a little torque steer and just wrote it off to a
high-torque engine in a front wheel drive vehicle. I now know better and
am VERY happy with the way that my coach now steers and handles.
Thanks to Manny for the front end work, Jim and Nick at Applied for
fixing my bent bogie arms to get the rear end under control. My coach is
now an easy one-hand drive.
