What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Bearing greese is migrating through inner grease seal and contaimenating brake shoes and drum surface resulting in a loss of braking effectiveness. Upon inspection all four wheel had contaimenated brakes.
Grease seals for wheel bearings on 3 out of 4 wheels failed at under 2000 miles. Grease leaked onto brake mechanisms, making them spongy. 1 out of 4 brake assemblies totally failed. Grease seals and wheel assemblies are manufactured by lippert.
We have had considerable problems with it, but never expected to find that the brakes, grease seals, and wheel bearings were in installed correctly. I became aware that there were many reports of problems with the grease seals and wheel bearings. I was in texas and we had the grease seals and wheel bearings serviced.
While camping with this 5th wheel camper, upon inspection of why the fenders were vibrating so much while traveling down the highway, two of the braces were broken and ready to fall off. Since then I inspect these braces because I don't want to cause an accident by one breaking off and hitting a car on the highway.
