Chassis coaches when the air suspension is lowered typically have the steering wheel turn.
So every time the coaches front suspension goes through its travel the coach is turning if the steering wheel is not turned to compensate for it.
Unihome moved the steering box way lower and the long Pittman arm parallels the suspension trailing links.
I think that starting in 97 they moved the box out farther from the centerline so as to match the wide body. Previous I understand the box was at the 96 width.
I noticed in my 97 from full dumped to full extension manually the steering wheel does not move a bit.
Fixed. No "bump" steer. Not noticeable on smooth roads. Big rolling bumps caused the coach to go to the right under compression then back to the left as the coach's suspension extended.
Told the ored customers just to hold on as if the ride height valves were good the coach normally came back to the original heading.
Used to dump the air three times then reinflate the chassis and measure the bumper height then extend the suspension to the top and let the coach auto level. Measure again.
If the coach returns exactly to the same height every time then the steering will be the same.
If the ride height is not repeatable in the coaches that have some bump steer then the coach will wander.
Spicer 710 boxes also needed the center spool reset after a few hours from new. Old ored stuff. Do not think the unihomes had the spicer but not sure.
