    Wheel bearings.

    I purchased a new BHS 367 in February. Currently have about 3500 miles of travel on it. Are the wheel bearing packable or sealed and how often would you do this.

    They are most likely open-type bearings that have to be packed. Personally I would check them now, to insure they are well greased and there are no nicks
    or gouges on the bearing and/or seal areas. If they are in good shape grease-wise, and in nick-free condition, I would check them every few years. Maybe
    after 20,000 miles or so. Or you could pull them and repack them when you do your other vehicle wheels.

    They are open tapered bearings requiring cleaning and repacking. Replace the inner seals each time. DO NOT use the Zerk fitting on the hub - that's there for marine applications and RV bearings should be cleaned, inspected and repacked at regular intervals (usually 10k miles or annually).

    Hi Rob. Not sure what outer seals you are referencing. I only have inner seals on my axles. On the outer end I only have the flat washer, castle nut and grease cap. Maybe you mean the grease cap.

    I misspoke - you are correct! (And the grease cap does not need replacing.)

    I just repacked my bearings at 3 years and roughly 2500 miles. 1 was pristine, but the three others needed repacking. If you pull the axle information off the axle tube and email Dexter, they will send you a build sheet on what you have with all the part numbers.

    Having that you can shop bearings and seals. If replacing a bearing you need to replace the race too so get the sets. I went with Timkin brand bearing and seals. Summit Racing has the best pricing I could find and very fast shipping

    I had my done by a local trailer place (not my dealer) but next time I will do it myself.

    The main thing with repacking wheel bearings is to make sure you get the, misnamed, pre-load set correctly. Many issues with wheel bearings occur
    right after a brake/wheel bearing maintenance job due to bearings set too tight or too loose, with too tight generally the culprit.

    Dexter has a how to video that shows the correct way (50 ft/lbs load, then back off to finger tight.

    However a warning - there are literally hundreds of other how-to videos and most are wrong.

    I would check them now. I did mine soon after purchase. The bearings were fine but two brake assemblies were toast...on one the adjuster fell on the ground when I pulled the hub. The other was missing most of the brake material.
    The delivery drivers use the trailer brakes almost exclusively to the dealers.

    I've had 5th wheels for 20 years, & these were the first shoes I've had to replace.

    Thanks Rob - I was wondering if I was missing something on a new axle.
