The sway arm bushings on my dads 2001 Half Ton 4x4 Ram are shot and I was curious what size bushing I need. They are either 30mm or 32mm. Which size do I need, Thanks

 

What size do you have? That's the one's you'll need :P.

Take a strip of paper or masking tape, find a fairly rust free part of the sway bar, wrap it around the bar, and make a mark where the paper meets the end...take that, compare it with a ruler, and find your mm...32mm is just a hair over 1 1/4 inches...30mm is under 1 1/4.
