Rebuilding my first 9" traction lock (bought used), and once I cracked it open, the clutches looked really good - but no shim. Apparently I'm not the first one in this one. Every build video I've seen, and every post I've read on it says Ford shimmed these. Would it be possible that it wouldn't need a shim at all? I don't have the right stuff to check the preload, I'm guessing it takes a special tool I don't have, and I don't have a spare 31 spline axle and chop saw to fab one, so I'm at shade tree level on this. Read where one guy said to assemble it without the 4 tension springs, and spin the carrier on a (fixed) axle. If there is drag you're good, if it's hard to turn it's too tight and will chatter on corners. Sound about right? I tried this with new clutches, and it drags pretty good.
Other than that, I'm not sure how I'm going to check the preload on the clutches, and I can't go back to the original shim(s), even if it would be right with them.
