Default Steering arm knuckles

I would like to ask......How tight or what are the steering arm end knuckle fittings specifications to be properly adjusted (where they are greased) ?

I don't have an actual spec but a good rule of thumb with all new parts (including round balls on the ends of the arms) is to tighten the plugs until they are flush with the opening and then just enough to line up the cotter pin hole.


I think I did read that you want 25% spring compression somewhere, how you measure that easily is beyond me.

This is easier if you have a caliper, but a ruler will be okay.

1. Measure the overall length of the spring.
2. Measured Length x .25 = Distance To Compress.
3. Grease parts as needed.
4. Install spring, and cup, and plug.
5. Screw plug in until all loose slop is gone.
6. Screw the plug in the Distance To Compress.

No, not the king pins.......looking at the cross bar.....and the other knuckle / grease areas. How tight should they be?

In my case, with rather worn balls on the drop-arm and drag link, I had to screw them in really tight before I reduced the "wandering" tendency on the road. Might be different if the balls were not worn.

They’re called the tie rod and tie rod ends.
