Review on Bearing Buddy 1.980 Boat Trailer Genuine Stainless Steel with Protective Bra & Auto Check Wheel Center Caps - Set of 4 (1980A-SS 42204) - 2 Pairs by Maurice Branch

I don't have a boat trailer but have a bike trailer with a tandem axle and four hubs. I've had various trailers over the last 50 years and a dry frozen axle with destroyed bearings is no fun in road temperatures over 120 degrees. They fit great, I froze mine for three hours before installing them and pumped lube in very slowly, letting the air out before pushing the blue slider out. Now that the slider is moving I know the bearing is filled with grease protecting the bearings. Most trailer owners, with the exception of boat trailer owners, never think about axle bearings, so once you have them installed you will be sure to check the bearing lubrication and keep your trailer happy. They are easy to install. The hardest part is removing the old cap from the hub. After installing the Bearing Buddy, I attached a suitable bra to keep dust and debris out of the Hub Bearing Buddy.
