Suspension Issues on Sabred 31REDS
I bought my 2010 Sabre 31REDS in late December 2009. Initially it had a few issues but the one that has the history was tire marks on the driver side wheel trim. I asked the dealer about it and they were gone after the first warranty service in January. Then I noticed that the wheels on that side were closer together (about 1/2 inch) than on the door side. Dealer said there was nothing they could do because the design had too much weight on the driver side even though there is no measurable lean.
My wife noticed it first but the common link for the springs between the axels, called an "equalizer" by Lippert, the manufacturer of the frame and axels, was always canted toward the front while the one on the door side was vertical. The geometry of this system will pull the two axels together when that happens and that accounts for the spacing difference.
End of long story coming, I promise. I have been to two other dealers, including one that Palomino actually recommends (not my purchase dealer, incidentally) and the problem is still not fixed. No one seems to know what to do even though the last dealer did make things better by loosening the bolt holding the equalized a bit. The frame measure out exactly square (even better the manufacturer specs I am told).
High school geometry tells me that if two pairs of points on two lines are at different distances, those lines can't be parallel. If the lines (axels) are not parallel, the tires cannot run straight on the road and the tires will not wear normally.
After five months of this I am tired and want to use my trailer with confidence. With about 2000 miles (including travel from the factory to Tucson where I bought it) there does not seem to be excessive wear, so I am wondering if I am just being too picky. It is an American-made RV after all!
