Just has taken a trip fishing and had a friend of mine following me in his car. He was saying the motorhome looked like it was leaning towards the passenger side. I've installed new suspension pillows and new shocks. I believe the suspension system is getting it level, but maybe not. I've purchased a new leveling arm for that side to see if that corrects this problem. Is there anything else I need to consider?

The height controller should work to keep it level if put on auto.
What year is your coach.
There might be a leak.

G'day,

Check the ride height as per the Maintenance Manual.

Sir: the leveling valve is adjustable. The nut that holds the arm to the valve covers a slotted hole. moving the arm up raised the coach. Adjust a little at a time and wait as there is about a 20 sec delay.

LOL...I didn't have anyone but me in the motorhome, but I have been putting on some pounds lately.

I will check the ride height, if that is low, then I'll look at adjusting the nut. Thanks guys.

Sorry, my GMC is a 76 Eleganza II.

Go cut a wood dowel to exactly 11 11/16" long and you now have a rear ride height measuring tool. Mine lives under the drivers seat in the compartment. Use to measure when parked on a flat surface from the ground to the top of the frame slot behind the passenger side rear wheel. The drivers side is blocked by the gennerator. I get the drivers side correct by makeing the back bumper level L to R. I have a flat smooth concrete area to measure on. Most have gone to the improved type adjusters on the height valves which are fittings on threaded rod with jam nuts. You can get it set up so the auto level is then calibrated.

John,

I like the dowel idea but better yet measure from the bottom of the frame to the top of the oval slot on the passenger side,
subtract that measurement from the 11 11/16 inches and make two "rear ride height blocks" from 4 x 4 instead of a dowel. They will
probably be right around 7 11/16 inches tall. A 4 x 4 will stand up and not fall over. While you're at it make two for the front end
as well they will be around 9 1/8 inches tall.

Jim Kanomata, Ken Henderson and Dave Lenzi all sell the adjustable links that go between ride height control valve and the bogie.

Not sure if it'd be noticeable to the chase car, but don't forget to check the front suspension leveling via torsion bars while you're making the rounds. Maintenance Manual has all the measurements.
