How often do you all grease your trailer wheel bearings ??
I thought I had the auto greasing axels but.....NOT
So I'm going to grease the by hand but how often should this be done ??
Be honest, don't tell me what the manual says but real life !
Thanks
I grease the wheel bearings in my Car Hauler every 5,000 miles. I load it pretty heavy and run a lot on the interstates, though.
Dexter Axle says to repack standard bearings every 12 months or 12,000 miles if your axles are in the 2300-3500# range. You can get your literature if you've got Dexter axles at www.dexteraxle.com
I have heard bad things about bearing buddy auto-greasers and electric brakes, but what is heard and what reality is sometimes differ. I have a bearing packer anyway.
I run Mobil synthetic in my fiver,, been three years since I have repacked them and several thousands of miles,, pull a wheel to check the brake pads and bearings every year and they still look like I just repacked them,, will not repack until I need to,,
have always thought the once a year rule was just to cover the MFGs hind end for any problems,, have towed close to 100k miles and never a bearing problem,,
often wonder why the trailers needed so much more bearing service than the tow vehicle in front of them covering the same road,,
I have dexter axles on the car hauler I have been using since '89. I grease them at the beginning of each race season and have no trouble going on 300,000+ miles. I have pulled and inspected them every few years and found them to be perfect every time.
The only trouble is that when using the grease gun its easy to force grease past the rear seal and into the brake drum (and thus grease your brakes!). Not good. I did this one time and had to clean the brakes and replace the shoes.
The one thing I always noticed about greasing them after each winter (the beginning of each race season) is that pumping in new grease always forces out a small amount of water (condensation I assume?). Always makes me feel better to see it purged.
I don't have the bearing buddies. I don't know if it is different now, but years ago what you did was remove your dust covers from the hums and put on the bearing buddy caps. The caps have hollow centers with a plate, spring and grease fitting. Periodically, you hook up a grease gun and pump them up, compressing the spring. They are supposed to gradually push new grease through the bearings. For boaters, you make the bearings more resistant to water.
Some folks have voiced concern about using these devices with trailers that have brakes. I don't have any experience with them personally, so I really don't know how they hold up. The only time I saw one was when I helped out some guy with a boat trailer, and that one was too small and too old for brakes. Perhaps Dexter has information on that, too. I didn't see any where I was looking, though.
