Adjusting your Caltracs can be - interesting while the car is sitting on the ground. You will need a pair of 1 1/8" wrenches. Adjuster nut to ground clearance will be a problem - unless you have a spare 1 1/8" combo wernch. I obviously stole mine from a guy that owned a J.D. tractor ( green). Cut it in half and open up the box end and you are good to go!
