FSM shows 125 ft/lbs and it is WRONG.

There was a thread a month or so ago that recommended using the torque value that is stated on the ball joint instructions. There was a post in there that quoted some values.

I would post what I remember, but that would only show you how bad my memory is.

I have new GM arms and they don't mention it on them.

OK I did the search for you.

It is a handy feature - click on "search" at the right hand top of the page. Enter "ball joint torque" and read all about it.

Just for this one time:

Ball Joint Torque thread from last month.

And for the lowers (since they weren't addressed on that thread) I want to say they're start at 75 ft*lbs and max out at 90 to get the pin in...but I don't have my manual or the paper that came with my new balljoints here, so don't hold me to that number.

They weren't? Hmmm...

Quote:
The correct torque is 61 upper, 83 lower.

OK, here's what I have regarding ball joint torque values--this is NOT from FSM, but from the Dana/Spicer info that comes with the ACDelco parts I use.

Upper:

1. Torque to 65 ft/lb

2. Locate cotter pin hole in stud then continue to tighten until slot in nut lines up with hole

3. DO NOT BACK OFF NUT WHEN LOCATING COTTER PIN HOLE


Lower:

1. Torque value varies by size, though minimally

9/16" 75-85 ft/lb

5/8" 80-85 ft/lb

2. Follow same procedure as for upper ball joint

Similar to Bill, the info I got was from (I believe) an old Moog box. Works well for me :
</font>
  • Upper : 55 ft-lbs, then tighten to next cotter pin hole</font>
  • Lower : 75 ft-lbs, then tighten to next cotter pin hole</font>
  • ALL the rest (tierods, idler, centerlink) : 35 ft-lbs, then tighten to next cotter pin hole</font>
  • Idler arm to frame bolts : 61 ft-lbs</font>
In all practicality, the difference between 75, 83 and 85 ft-lbs is gonna be a small fraction of a turn. In fact, it's possible that after going to the next cotter pin hole, they'd all be the same anyways [img]smile.gif[/img]
