I will check for type of nuts that are on our u-bolts. I thought that they were of the fared washer type that is self locking. With todays standards the old so-called lock washers are not used as thay can break and spread out from under the nut with force. All truck u-bolt have a flat continuious washer under the nut that has extra heigth and threads for more strength and is of grade 8 or more for quaility and added tensile. The ny-loc nuts with the nylon as a locking mechanism are difficult to find in a grade greater than 3 ( poor quality).
