Is there a figure used for "acceptable" pin box flex? Doesn't seem like with the amounts of weight involved there could be zero flex. Anyone know of a tolerance figure (e.g. 3/8, 1/2 etc.)?
I measured the flex on our new Mobile Suite and it was 3/8 to 7/16 and Lippard maintained that to be the norm. I suppose with 3500 lbs. or so of pin weight maybe that's why. In 20,000 miles nothing has changed.
