84 CJ Ball joint question

just installed a new set of moog ball joint set everything to spec except split ring torque to 45 in stead of 50Lb how stiff should the knuckels be they are stiff but still moveable, not a one had job but not straining with two hands. Is this normal? will I have problems returning in a corner. it did not return before hopeing new ball joints will take care of this.. Thanks everyone

Why didn't you set the preload to 50 ft lbs?

You said it didn't return to center... It could help but did you change the suspension in any way?

Vibration? Bump steer? Wandering? Read the article (sticky) on Steering, suspension, and driveline.

The 50lb preload is used to stretch the metal not control how stiff the joint appears. If you don't preload the joint during installation the metal will stretch later and leave you with a lot of slop. Preloading suspension components is the same a torquing a head bolt; steel stretches up to a point and it's that point you need to get to for a fatigue free joint.

These, in the day when heaven was falling, The hour when earth's foundations fled, Followed their mercenary calling, And took their wages, and are dead.

Their shoulders held the sky suspended; They stood, and earth's foundations stay; What God abandoned, these defended, And saved the sum of things for pay.

I know this is a silly question,

But did you torque the bottom ball stud FIRST? before you put the split ring in and torque it?

The bottom has to be done FIRST,
Torque to about 75 Ft.Lb.
Then the split ring to about 50 Ft.Lb.,
Then the top nut to about 100 Ft. Lb.

If you don't do torque the bottom first, you will have all kinds of problems...
----------------------------

Did you grease the ball studs yet?
Adding grease often makes them MUCH easer to work with.

Mine were Moog, and VERY stiff when first installed, but they seated in just a mile or two and work PERFECTLY now.

I've read the same thing. Something about a Jeep (dealer) mechanic remembered wandering until they started to torque to 45. Too much preload is a bad thing too.
