Be sure and know your bolt pattern before your purchase. The center stud to center stud measurement can help you determine your bolt pattern. Bolt pattern measurements are as follows. 2-5/8″ is 4-1/2″ bolt pattern, 2-3/4″ is 4-3/4″ bolt pattern, 3″ is 5″ bolt pattern, and 3-1/4″ is 5-1/2″ bolt pattern. If you choose the EZ Lube grease cap option for your hub, you will be able to lube your bearings easily and cleanly. Simply remove the rubber plug on the grease cap and attach a grease gun to the grease zerk fitting on the end of the spindle and pump the grease. It allows easy flow to both inner and outer bearings. Quickly lube your bearings easy and mess free. Increase the life of your trailer, by using Miller Auto Technology’s top of the line, durable, quality replacement parts.
