... all graded fasteners should be only a one timer
I don't believe that is the case. It's fine to reuse bolts unless the manual says otherwise or they are damaged.
U-bolts are a different deal as discussed previously. Fasteners have a specific tensile strength and they stretch upon use by design but if they are tightened past their design limits they are prone to breakage and often distorts the components they are holding together. They'll never again torque up right after that. Everybody wants to reef stuff down WAY too tight for some reason.
One more thing on the bolts. Remember the explorer tire thing. The ford manual said to run the tires lower than the tire manufacturer . We all know what happened . Anyway nuff of the bolt stuff it drives me nuts. (yes pun intended). Back to f-100 alignment. I got the spindles off tonight and the pins are rough not all but in some areas also I have to drill and tap 1/8npt grease zerks the 1/4 28's are stripped out. Also brought home the flat head. The rough spots could be what I was feeling in the steering also got the shims in the mail today 4 degree.

NO TEDSTER9 I BET YOU DO STRUGGLE IF YOU REMEMBER YOU SAID IT IS FINE TO REUSE BOLTS UNLESS THE MANUAL SAYS OTHERWISE. TEDSTER9 THE BOLT MANUFACTURE DOES NOT SAY THAT TEDSTER9. TEDDLY TO NOT TRY TO INFLATE TE BOLT
SOME graded bolts or fasteners (though not "all"), must never be reused. Any bolt that has been tightened past the yield point should be replaced, at least in critical applications. A U-bolt probably qualifies for a couple different reasons.
I realize what everybody does in practice, but at least people should be informed that what they are doing (or not doing) is not good practice.
Ok just went for a test drive installed new king pins new tie rod ends new this new that. Did not put shims in and do not have new springs in yet. Steering is better but does not self center yet. Really did not think it would. Now on to the shims and lower front springs. Learning a lot again as I get back into this. Good afternoon spent with the son in law. Will update again when shims are in springs and sway bar.
Back to working on the truck. Got the axle and springs out from under this afternoon. I found some shims in it already but they were in backwards from my line of thinking.I have two pictures the shiny(aluminum) is the new one that I am to put in the steel one is the one that came out.The thick end was facing forward and to my line of thinking would put neg caster in with the axle on the bottom of springs. Side by side they look to be just about the same on the steel one their is a part number what ever that means.
old on left mid-fifty on right. What is the part # on steel one ?????
They look about the same to me. I am going to put the new ones in.
What is the correct length that front spring center bolt should protrude into the axle ? The one that is on the new eaton springs (mid-fifty) with shiny spacer wedge in previous photo would go into the axle a depth of 3/8" the actual hole for the bolt is 3/4" I am getting tired of waiting for mid-fifty to ship the new bolts that I bought over a week now and want to get it back together.
