According to the Dexter manual, your u-bolts, which connect the axle to the spring packs, must have the nuts torqued to between 45 to 70 lb ft, if they are 1/2 inch. Quite a few owners have discovered loose nuts, and this could be the cause of spring leaf movement. If you are 'oiling' suspension components, this must mean you do not have wet bolts with bronze bushings in your suspension. This is a good upgrade, which will keep things together much longer. The units that do not come with the wet bolts usually have plastic bushings and thinner shackles, which tend to wear much faster than the upgraded parts.
