How hard is it to replace the trailing arm bushings on a cx613 with the maxair twisted sister suspension?

[Larry H]

Need to replace the bushings in the trailing arms on my cx613 tandem axle . Found a bushing kit and just wondering if it was something I could do without any special tools. Also need to replace the torque rods, are they both the same length? My front axle has a shorter one but is built up with flat washers like it was a quick fix. Got a part number for the rear axle but all the schematic drawings show the same set up front and back . Thanks guys for any help, I'm just trying to keep as much money in my pocket as I can.
