Newmar motorhomes on Freightliner chassis can experience rough rides due to improper ride height adjustment, incorrect air pressure settings, or suspension component wear. Most issues can be resolved through proper air bag calibration, shock absorber maintenance, and ride height adjustments.
When Power Gear levelers won't retract but deploy normally, the issue is typically a faulty retract solenoid valve, damaged wiring, or control module failure. This comprehensive guide provides step-by-step troubleshooting to identify and fix the problem.
Levelegs and air suspension are separate systems. If coach wont raise, check that levelers are fully retracted, air compressor is running, and no air leaks. May need professional service if stuck low. Do not drive with suspension issues.
Front air bags not filling with air exhausting from height valve means the valve thinks chassis is too high. Check linkage connection and adjustment, or replace the stuck height control valve.
Leaf springs rarely need replacement unless cracked, severely rusted, or visibly sagging. Your 30-year Arizona springs with no rust or sag are fine. Replace bushings as planned.
Off-center steering wheel fixed by adjusting tie rods equally both sides. Return to alignment shop if recently done - they should fix free.
Running mismatched airbags (one with jounce bumper, one without) is generally safe if you maintain proper air pressure and never run the bags empty. However, matching bags is the ideal long-term solution for even performance.
Ford F53 cruise control uses a 3-pin contact ring system. Bent contacts are common and can be straightened. Clean contact surfaces and check continuity while turning the wheel.
Power remaining after key removal indicates failed ignition switch or stuck relay. Test for voltage on run circuit with key off. Check for hot relays in fuse box. Ignition switch replacement is straightforward if confirmed as cause.
