Today I decided it was a good day to grease the chassis of my 2013 Sportsman 550 with Polaris' grease. I found four zerk fittings each side for the front upper and lower A-arms and five zerk fittings per side for the rears. The rears were not too bad but the upper A-arms for the front were a bitch to get to as I could barely get my hands in there from under neath. After struggling and hands cramping up I finally got those boogers done. Anybody have a trick to accessing the upper A-arm grease fittings easier than I found? I tried a 90º angle adapter but to no avail and just went with the standard end of my flex hose. Also, I wanted to grease the u-joints with Polaris u-joint grease but I did not find any zerk fittings on either the front or rear drive shaft. Are the u-joints for the 2013 Polaris 550 not meant to be greased? Is there access to installing a zerk fitting for the u-joints or not?
