I finally got my front end finished, New upper and lower arms,P/S deleted, new centerlink, tie rods, Flaming River steering box 1" sway and 600# coils. I have not aligned it yet, but I shimmed the uppers exactly as they were before. I also set the toe in myself for a couple trips around the block. It drives great, but the passenger side upper arm shaft came loose and made some noise. I jacked it up and I could tell the upper arm shaft bolts (the ones with the grease fittings) had come loose. I set up the shafts correctly before install. I just tightened them up but is there anything else I should do or check? By the way I like the stance with the new coils, kind of aggressive. I need to reaim the headlights though, they shine about 6 feet in front of the car  Thanks for listening to the ramble Nick

They have to be real tight Nick.
The original correct nuts had peened threads at the end of the nut to help keep them from loosening up.
I would use a nyloc self locking nut.------------------

Alex I think hes talking about the pivot shaft end nuts that thread into the uca itself. It sounds as if as the arm traveled up and down it worked them loose. I dont think theres a nyloc with that funky thread at your local hdwe store....lol [This message has been edited by TT670 (edited 04-04-2004).]

Thanks for the quick response Alex, but TT670 is right. It's the pivot shaft end nuts I'm talking about, I just didn't know what to call them  Nick

Nick,
The pivot shaft end nuts have a very specific factory recommended procedure for installing them, and I think now you know why!
Ford calls for a spacer to be placed between the ends of the control arm while the nuts are evenly installed and torqued from each end. This way the arm won't distort when you tighten the nuts (it would tend to draw the ends of the arm together). I don't have my shop manual in front of me right now but I seem to remember the torque spec is around 100lbs-ft or so.------------------

Thanks for the responses, I found my problem. I pulled the arm off to inspect it, and found that I must have crossed the threads of the pivot shaft end nut on one side when I put it together.I am just going to buy a new arm and try again. The job is pretty easy with the shorter springs (no compressor needed). I love doing things twice good practice!! Nick
