darky32, the simple answer to it locking up when you fit all the supplied shims, and of course the locktab, is that there are never enough, and you should always save the old shims for re-use. Keep any left-overs for the next time, which will be in at least 50k miles if you have done it correctly, moving freely with just a trace of end float, and grease them regularly with Castrol LM.
As a matter of interest, the original manual said that they should be greased every 1000 miles, and that would do no harm at all, although I think the interval was extended later. I don't have a copy of a later manual immediately to hand, but as the greasing is a very quick job, and saves lots of money in the long run, I would suggest doing all 8 nipples every 3000 miles or so, i.e. at every oil change and half way in between.
