Trailer Bearings and grease

lo23m8b · 07-18-2019, 10:09 PM

I've been using Mobil 1 red synthetic as of late because I can no longer find the old Hi-Performance Hi-Temp Blue. It's seems OK. But never mix greases because if the bases are different it will break down. If you are using a new product fully clean the old bearings then pack them good. Regular maintenance is the key. On the job for 50 years.

All of the bearings and seals for that axle are available at NAPA. I also have 5200 LB Dexter easy lube axles under my trailer. I have been using the NAPA bearings in my trailer as needed. I have been using the Valvoline red tacky grease. I do tow long distances at times. I have had some issue with one axle and hub killing the outside bearing and race. Recently I put a new hub. brakes and bearings on that spindle. so far it has been OK. If your tires have a weird tread wear it can put more pressure on the bearing and overheat it.

Mike, do you happen to know the part numbers for the NAPA bearings and seals? Do you just tell the counterman that you have Dexter 5200 lb axles, and that is enough info for them? My trailer tires are not show any unusual tire wear, but it does seem odd that the bearings on the front axle looked fine, but the rears looked so bad. I wonder if the torsion axles are more sensitive to load distribution than leaf spring axles with a center pivot link. My trailer looks level while towing.

These are the NAPA numbers that I have been using. I have a small tool box in the trailer that I keep a spare set, grease and a grease gun.

PBR25580 inner bearing
PBR25520 inner race
PBR6 - outer bearing and race
22532 seal
