That snap ring is a bear. I bought every pair of snap ring pliers I could find and none of them worked. I eventually built a set with really long handles - like 18 or 20 inches long. They're ugly and crude as hell but they worked where nothing else did. The zip tie idea looks like a winner for putting the snap ring back in but it was getting the miserable bugger out that had me stumped. Good luck. I wouldn't dream of driving it without the ring.
