Boat Trailering Guys:,
I have a double axle marine trailer and want to check the bearings and grease packings. Can you advise how one does this, what to look for, and what type of grease to use? Thanks.

Here are the steps to perform this task: -Remove the wheel from the hub. -Remove the bearing dust cover or Bearing buddy from the hub. -Remove the cotter pin from the spindle and loosen/remove the castle nut. -Pull the hub off of the spindle, you may need to tap it slightly with a rubber mallet. In most cases the rear seal and bearing cone will remain on the spindle. Remove them carefully if you plan on reusing them. Regardless of the condition I recommend replacing the seals after removal. They are easy to damage or tear without realizing it. -Clean all of the parts with Kerosene, diesel fuel or a solvent. Do not use gasoline. -Inspect the parts (bearings, seals and races) for rust spots, pitting or discoloration (from heat). Roll the bearings in your hand, they should turn smoothly. -Inspect the axle spindle. Look for pitting, scoring or excessive wear. These are indicators of problems with your bearings. -You will either reuse your existing parts with replacement seals or you will find that you should go with replacements. -Repack the bearings with a premium quality wheel bearing grease found at your local marine supply store. -Finish reassembly.
