Our 2011 trailer already has squeaky suspension(dual axle, leaf springs).On our previous trailer I found that the shackle plates were shiny where they rub against the spring eyes. The only way I know of getting grease in that area is to modify the bolts by drilling a 1/32" hole along the centre of the bolt, cross drill at the centre of the bolt, then add a grease fitting in the bolt head. The grease then flows thru the bolt, fills the bushing from the centre out until some grease gets forced between the shackles and the spring. It was a bit of a job on the old single axle(6 bolts) but worked well. The new dual axle has 14 bolts. I was hoping someone has an easier way of fixing this problem.
