Compressor is located under vehicle, below passenger front. Put treg in xtra high suspension setting. Hold suspension lock until it is locked out. Remove plastic cover underneath passenger side to get at the compressor (T27 bolts). Disconnect the two compressor electrical connections (small flathead screwdriver). Remove the three bolts holding the compressor support (13mm bolts). Tilt the compressor until you can access the two bolts that connect the two cylindrical bodies of the compressor located at the piston head (T27 bolts). Clean around the junction. Pull the parts apart to reveal the o-ring and the piston head. Take note of the piston seal orientation. Replace the piston seal and o-ring. Button it all back up.
I think you could adjust the amount of play the compressor has and make it run more quietly by adjusting the tension on the isolater spring (wide flathead) while you have it accessible, but I did not think of this until after putting it all back together.
