2002 Coach Leveling Question????
The left rear of my 40' 2002 coach is lower than the right side. I was told by a tech that to adjust the unit, I need to raise the coach to max height, turn off the ignition
key, crawl under the left drive wheel, and loosen the 1/4" hex nut, slide up the rod 1" and retighten. The problem is there is no way to reach the nut since it is located inboard of the inside tire.
Any suggestions. One was to place the coach on jacks, and remove the two left wheels. I hope there is a better way to adjust the height.
Thanks for all Help!!!

Billy,
If you raise the coach to max height, look over the drive tire and see if you see the leveling valve mounted to the frame inboard of the drive tires. You should see an arm extended from the valve and at the end of that arm, a second vertical rod. There is usually a rubber "P" that acts as the connector. The rubber "P" has a hose clamp that tightens it to the vertical rod.
Before you reach in there !!!!!! Crib the coach with wooden blocks, jackstands, or something substantial. You do not want to put yourself in harms way at any time working under the coach or in a pinch point. You must put something under the frame to keep it from sitting down on you. Obviously, turn off the engine and ignition. This is very important. Turning off the engine, turns off the travel solenoids and isolates the height control valve. Now, reach in and loosen the hose clamp on the rubber "P" and move it in the direction you want the coach to move. If the coach is low, move the "P" up. Retighten.
Next step is critical, and can foul you up if you do not it this way. Manually lower the coach below the normal ride height, put it back in travel mode, and give it time to settle out. (make sure you remove the cribbing) If it's level and at the correct ride height, then you are done. If not rinse and repeat. If you just allow the coach to settle from it's jacked up position, it may give you a wrong reading due to the deadband in the HCV.
I am skinny enough to work in the fender well around the tires. If you can't reach that far, you will need a few helping tools. One, something long to loosen and tighten the hose clamp. Two, a pry bar of sorts to move the "P" up or down the rod.

Billy,
You need to also know how high the coach should be at the correct ride height. According to Newell my 1999 model needs to be at 12.25" This height is measure from the wheel well behind the front wheels and the wheel well in front of the drive axle wheels down to the ground.
All four measuring points should be close to 12.25"
I will take several measurements and adjustments to the hose clamp on the rubber P to get everything even.
I crib my coach by putting 6" x 6" x 18" long oak blocks under the skid plates that are welded to the frame. Please be extra careful in placing these cribbing blocks; your life may depend on it!

Can anyone tell me if all Newell's have the those skid plates welded to the frames? I really like the idea of knowing you can use this cribbing.

Yes, mine are. They are useful when going into low lying areas.

Skid plates saved my ass yesterday. I was trying to depart an RV park in the California Delta, and would have been stuck on an island without the skids.
