Hi Robby, My name is***** will be glad to help. What is your PM interval on your trailers and also what grease brand and type are you using? this makes a huge difference as cheap greases will wear off quickly. an extreme pressure and environment "sticky" type grease will cost more but save you in the long term on parts life. Tractors and trailers should be greased weekly if they are used daily. These parts are manufactured and machined/made to specs but you may notice longer life with the bronze bushings.
OK good. Be sure the anchor pins are changed and the drums are in specs and the brakes are in adjustment and slacks both manual and automatic are functioning properly. Make sure all the yokes and clevises are antiseized and not seized putting a strain on the slack adjusters. I am on my way out for a few hours but we can post back and forth as needed.
