Replacement Bearing Kit for 3500lb Axle on Forest River Flagstaff 19QBHW Camper


I aim to inspect wheel bearings on 2016 Forest River Hardside Trailer Model 19QBHW and I want a set on hand. Will Hub Bearing Kit for Lippert, Dexter, and Al-Ko Axles - 3,500 lb with #84 Spindle Item # BK2-100 fit this model?


Expert Reply:

Given its 3331 GVWR, your 2016 Forest River Flagstaff Hardside 19QBHW very well likely has a 3500 lb axle. I have no way to confirm this, however as the RV manufacturers don't provide an online database that lists which component parts are used on a given year, make and model like the automotive manufacturers do.

You can easily confirm this by pulling one of your hubs and measuring the diameter of the spindle where the inner and outer bearings ride. The diameter where the inner bearing rides should be 1.378 and 1.063 for the spot where the outer bearing rides. Using an inexpensive digital caliper like # PTW80157 is recommended so you can get an accurate measurement. If you confirm those diameters, then the # BK2-100 is the correct replacement bearing kit.

The kit includes the replacement inner and outer bearings and races, a 10-19 grease seal, a replacement tang washer and a cotter pin.
