Ball Joints on Cevy

[Anonymous-0]

Going to do ball joints on my 82 chevy k-20, but dont remember how to set them with that threaded sleeve on the upper one. Anyone know?

Ben,

If you're doing what I think you're doing, then you're probably replacing the ball joints with the after-market adjustable upper bushing type?

Think you're about going to have to get it on an alignment rack to set that camber because as I remember it, that upper bushing is built as an eccentric that allows adjustment?

Just don't think there is any way you can "guess" at it.

On those, the upper sleeve is simply threaded (they ARE concentric), and you screw it down so the upper balljoint and the lower balljoint BOTH bear the load of the weight of the vehicle.

I can't remember the exact procedure, though. I'll try to remember to look in an old manual today.

Hi Ya Bob,

Yes, but you're talking about the standard, factory replacement types.

At one time (anyway) there was an aftermarket kit available built on an eccentric, which would allow for a certain about of "tilt" at the top of that wheel while still maintaining the compression on the bottom joint.

Darned if I can remember who marketed it but do recall that it was just an old-fashioned “bastage” to adjust.

GM simply calls it an "adjusting sleeve" and I assume you've got the special wrench to fit it.

I usually tighten the sleeve just enough to put some pressure on the upper-ball joint tapered pin. But - this is what GM says about it:

Tighten the yoke upper ball stud adjusting sleeve 50 ft. lbs. using spanner J-23447. Then torque upper ball socket nut to 100 ft. lbs. After torquing, do not loosen to install cotter pin. If necessary tighten more to align cotter-pin hole with slot in nut.

MARIS "nailed it".

You are thinking of a "DORF"!
