We have a 21', class C , 1986 Dolphin MH with 43000 mi. The rear
springs are about flat or straight across , no upcurve. Friend told us
we shud look into having them repaired or replaced. I called our
mechanic and "spring" guy and both said rebending and/ adding new leaves
would raise rig. Figure this is so but when I asked why they told me it
would prevent bottoming- but it doesnt bottom- and would prevent sway
and bounces- dont think it sways or bounces. Guess Im wondering why I
might need new springs and/ or would new shocks be advisable? Is there a
safety concern like the spring breaking?

Any info and/ or advice would be greatly appreciated.

Thanks
Richard

Hi Richard, A friend of mine has the same situation with his rear
springs - no arch. I am not sure that it is a problem though. I
think the weight of the camper just causes the springs to be flat.

My Sunrader has a set of air bellows that allow me to adjust the
rear suspension. J.C. Whitney sells this unit specifically for
the Toyota 1-ton Micro-mini motor home with dual rear wheels, for
$239.98. I have taken mine off and re-installed them with very
little effort (I had a slow leak I was trying to find). To keep
mine at the right pressure I installed a KMart 12 volt adjustable
air compressor ($29.95) in the line to the air bags. I also put
a check valve in the line to keep the air from bleeding back through
the air compressor.

Well, this is probably more than you wanted to know. I am pretty
sure that the other members will tell you that their springs are
flat also. A set of air shocks may be a simpler answer. I don't
think a set of regular shocks will make any difference in the arch
of the spring.

Hello Richard,

I to had flat rear springs. I went to a frame service place in
Ankerage ALASKA and looked for air bags for it but the dealer checked
and found that the sway bar is in the way. So I followed his advice
an he removed both spring assy.s and added a custom made thick
booster leaf. I was about twice as thick as a regular leaf. That
brought the body of the camper up about 3-4 inches and I didn't drag
every time I left a gas station. Also the sway was much better. The
job cost me about $ 330 and included some other small items he tended
to. I thought the price was very resonable, and the frame is level
front to rear. Now I'm going to add a trans cooler as others have
done.

get back if you have any Questions
