Spring bushings & shocks bill jacobs 3-5-03  
The nylon bushings wore out on my 31' Dutchman causing the axle to run out of alignment, result one tire blistered and the tread wore out on one side. I was told that nylon was all they had to replace the bushings but I could get greasable pins. You don't grease nylon. After some checking I found an Industrail supply place and ordered bronze bushings with the correct OD & ID but had to be cut to length. These can be pressed into the spring eye with a C-clamp. I then reamed them out to insure no burrs and inserted greaseable pins, so now I can give them a couple of shots of grease to keep dirt out and lube the bushings.
I also decided to install shocks on each axle at the same time. I cut the heads off some grade 8 bolts and welded them to them bottom spring plate for the bottom mount. Then with the trailer on jack stand and the axle hanging with out the tires I placed the shock on the bottom mount and put a marker in the upper eye to place a arc at each location. Checking for obstacles inside and outside the frame locate top mounts holes equally for each axle. I angled the front axle shocks forward and the rear to the back. I used grade 8 bolts and used bushings so the shock was perpendicular to the axle.
The trailer pulls better than it did when new. The bounce on concrete roads has been almost eliminated. I think all trailers should be built with shocks already installed.
Monroe had a web site with info on choosing the right shock. I was cheaper to order the shock thru an auto supply rather than the RV dealer. I had less than $400 in parts and did the work myself, outside with cold weather. The hardest part for the do-it-yourselfer is reaming the bushings but you could get by with a drill bit (properly sharped or new)and plenty of lubrication.

Bill Jacobs,
As the largest and oldest manufacturer of Bronze Bushings specifically designed and manufacturered for the vehicle suspension and undercarriage industry, I enjoyed reading about your experience. Bronze is a "tried and true" bearing material. I am sure one of our distributors is in your are, They would likely have a Bronze bushing in stock to fit your application. In the event you need something that is not standard, call me, we'll see what we can do.
