My son and I will be replacing the ball joints on his 1984 944. We have reinforced steel arms and the ball joints are bolt ins.
We are trying to find the torque specs for the three ball joint bolts as well as the pinch bolt that locks the ball joint to the steering knuckle.

Appreciate any help....

Hmm,
Tight, but not super tight. I have usally done these tight as reasonable 3/8" drive rachet if typical length.

one sec fred, i am loading my other computer to check the manuals.

Well looks like the ball joint to steering knuckle is 37ft/lbs. Still looking for the ball joint bolts

PorscheDoc

I can not find anything on the early ball joints, but i would guess somewhere around 25ft/lbs

The original BJ has been replaced as it has rivets and need snapped off to replace the joints. So the bolts you have need torqued to the bolt spec needed. And they are most likely SAE not Metric. Just get them good and tight and you will be fine. Use Loctite if concerned. The pinch bolt can be tightened to snug fit. The BJ shaft has a groove and the pinch bolt runs in the groove keeping the shaft from moving up/down. So just get it tight by hand.

You won't find a torque spec in the manual for that. Just look up a normal torque for the bolt size and grade and use that.

The 3 bolts that hold it to teh arm (where the rivets are) you probably don't want coming out. I just torqued mine as far as I could with a 3/8 ratchet and they have been fine since.

According to the Haynes manual, and these are the values I've used many times -

balljoint to control arm (three per side) 10-12 Ft-lbs

balljoint to steering knuckle (pinch joint) 37 Ft-lbs

Make sure to use hardened bolts and nuts for the balljoint-to-control arm application, as well as hardened washers. The washers are important for properly spreading the clamping forces. Loctite on the threads is a good idea too.
