Between the trunion and the cross shaft. Check for any up/down and/or side to side play, as well as any "wobble". Next, check for any overly worn areas on the roller tip. Check it for out of round and/or flat spots. Last, check for wear at the push rod contact point. From personal experience, the wear I've seen most common is excessive wear in the trunion with the needle bearings. One or more wear faster, creating a slight out of round condition. Once this starts, it wears rapidly until it becomes egg shaped. Actually reaching this point is unlikely because you would have heard it long before it became visually egg shaped. There shouldn't be any play between the shaft and the trunion. If there is, wear has become too excessive. The best way to see what I mean is by comparing one of your old ones with a new, unused one, if possible.

Take care,
