Question about ride height

DFR · 04-09-2008, 05:22 AM

Last fall I purchased a used 2007 Gulfstream on a FRED chassis. I drove it home from Indiana and immediately stored it for the winter. In going through the manuals this winter, I found a letter from Gulfstream stating the responsibility of the purchaser to have an alignment and ride height adjustment made after purchase. The unit I bought had 4200 miles on it. It was built in Indiana (obviously) and sold on the east coast. I purchased it in Indiana. Obviously the initial owner didn't put many miles on it. I plan to have the alignment done, but my question is, is ride height adjustments something that is only done on DPs with air suspension (which I don't have) and is Gulfstream issuing a one size fits all letter in the paperwork or what?

Your best option is to call the customer service number in your owner's manual and inquire, have your MH serial number handy.

I have had two C Class coaches. One was built by Four Winds and the other, my current coach, was built by Gulf Stream. Both came with the disclaimer that said the coach should be checked for proper alignment. Apparently, the theory is the alignment is done at the chassis manufacturer before the coach body is added and then it is up to the owner to have it checked again after weight is added.

Yes, ride height adjustment is an air suspension thing. Adjusting height on a spring chassis is rarely required and would need physical shimming to accomplish, not a few turns on an adjusting rod. My guess is that you got a "one size fits all" warning.

Alignment on a motorhome chassis changes when the body is added and may well change again when loaded with gear, water, etc. Getting a new alignment once the coach is in its "going down the road" trim is always a good idea.

In gas units, I think the allignment has more to do with the drive shaft allignment which has to be done after the coach has been added to the chassis. My 1998 class C had to have this done after I got it to eliminate drive train vibrations when decelerating.
