99 Tr21 with original MFI tandem trailer. After hearing numerous horror stories about the single leaf springs breaking and leaving guys stranded on the side of the road, as well as the constant squeeking with every move, I decided to rebuild the original suspension. New triple leaf springs, equalizers, bushings and greasable wet bolts. Nothing had ever been apart, impact wrench, PB Blaster and a big fu%#ing hammer a must. You can see in the photos the bushings were shot and the bolts had started hogging out the holes in the equilizer. About a 4 hour job with the boat off the trailer. Replaced the plastic bushings with bronze.
