Sure Lube Protection
When it comes to protection, nothing beats the patented power of Sure Lube. There are no springs, rubber plugs, or o-rings. Sure Lube uses a revolutionary double lip spring-loaded seal that ensures outer/inner bearing protection from corrosion, wear, and water entry. It's a time saver, too. Sure Lube lets you grease or repack bearings with just a hand grease gun and without disassembly. When only the best will do, use Sure Lube from Reliable.


Sure Lube Data Sheet
To ensure proper lubrication for the Reliable Sure Lube System, each unit should be lubricated with a high quality wheel bearing grease. This should be applied with a hand operated grease gun every three months, 1000 miles, or as use requires. Using 1½ - 2 ounces will give proper lubrication, and 5 - 7 ounces will completely exchange the grease throughout the wheel hub.

The grease seals that are used in the hubs equipped with the Sure Lube System must be a "Transcom" Brand of grease seal. These seals can be purchased direct from the factory. These seals should not be cross-referenced over to another brand of seal if they are being used in the Sure Lube System.
