[AT] More trailer questions..

[JAHaze at aol.com]

I have a tandem dual gooseneck trailer.  It's a Cornpro built in 1991 and has 
seen 1-3000 miles per year.  It has oil bath hubs on it that seem to hold oil 
just fina as I check it often and have only had to add a little.  My question 
is this: I hear things about bad wheel bearings in trailers, but I have no 
idea how to tell if my bearings are going bad, and even worse, what to do about 
it if they are.  Can anyone on the list give me a few things to check before I 
run into a big problem going down the road with a full load?  I need to add a 
few things to my winter check list.  Thanks.

Enjoy, Joe
