I have a 2014 Year RZR 170 and trying to lubricate. No problem with the a arms by front two wheels. However the inside a arm Zerks are a bear. I was only able to do one out of four. I tried with 90 degree grease gun adapter and didn’t help. I also tired with front lifted with ate jack and that didn’t help. I can’t get the grease gun to lock on these three Zerks. Seem to be a little off angle compared to the one that worked. There is a plate above with holes and it and I try to go through hole but still at wrong angle.

Anyone have success and how?
