Matt, Have you compared the new castle nut height with that of the old ones? Castle nuts and slotted nuts are available in different heights. In the process of doing my front end, I lost one of the slotted nuts for the lower control arm shaft. After I bought a new one at my local NAPA. I discovered it was shorter than the one on the other side and did as you described. Looked all over Albuquerque to no avail for one the same height. Finally had to go to the McMaster-Carr website, http://www.mcmaster.com/param/asp/psearch.asp?FAM=slottednut&session=desc=Nu ts;slottednut, and order it. Couldn't beat the deal, $.35 charged to the credit card with free shipping and I got exactly what I needed! As far as the centerlink goes, make sure both the holes in the idler/pitman arms and the studs on the centerlink are free of grease. I'd wipe off the stud shafts and holes with a degreaser. Also before you install the centerlink, thread the nuts on by hand and make sure they thread all the way on freely. There may be paint or whatever on the threads causing the nut to tighten prematurely. Once you have the centerlink in place, you may even want to give the back of it at the studs a slight tap with a plastic mallet to help get it seated before you try to tighten. If the problem seems more than just a slight slipping, I'd compare the studs on the new or rebuilt centerlink with the studs on the old one. You'll need to keep the stud taper in mind when you measure. Just a wild shot in the dark, but it could be whoever rebuilt the centerlink installed the wrong studs.
