How many of you have busted a U-joint on the trail only to find that the ears on one (or both) of the yokes have compressed too much to get a new joint in it? Simple fix is to carry about 1 foot of 1/2" or 5/8" all thread with a few nuts and fender washers. You can then position the nuts and washers on the all thread inside the yoke and open the ears right back up with a couple of end wrenches. Have done this many times over the years and it works like a charm. You can really dial them in for perfect fitment of the joint as well.
