I wrote much of the Dexter maint manual back in the day. Glad to see it available online.

What Tim and Milt stated is generally good advice. Based on what I saw for warrantynclaims or in the engineering lab, consider the following:

Trailer mfgrs tend to use absolute minimum axle and tire sizes, so pay attention to loadnratings. If your tires wear on the outside, it has been overloaded and the camber is gone from the axle.

Check your nuts (lug) often.

Brake adjustment is key. Even if you have self adjust brakes, the brakes are still probably under adjusted unless you do a lot of backing. Back up and hit the brakes multiple times to keep adjusted.

On sprung axles, make sure the spring is not binding, the hanger bolt may be too tight which will break the spring eye over time. Also, keep an eye on the spring bushings and replace as needed.

Older Torflex axles with open bracket may be cracked.

Use a good quality grease and repack the bearings depending on use. You don't need to go crazy packing the hub full of grease, just do the bearing and races.

Likewise, don't go nuts on the EZ-lube grease axles The grease has to go somewhere.

Discount what I just said if you have a boat trailer, the grease will displace the water.

Bearing buddies will make a mess and blow out the seal.

Probably the worst thing for the bearings is having the sprindle nut too tight.

If you have a trailer that mobile home axles, remember those were designed to be disposable.


Btw- i hate my ipad keyboard
