Part of the problem with my suspension was the over greasing of the original bushings pushing out the seals and of course letting road grit and water in. We're not greasing Cat Tracks so a little goes a long way.
Once you install bushings in place of the needle bearings the first time you go to grease them you will wonder if you dis something wrong as it will be very hard to pump the grease in. This is because of the fact that you now have a solid bushing to shoulder fit with very little clearance so the grease really has no where to go. All that is needed is one or two pumps once or twice a year at the most.
