Howdy-

I'm nearing completion of a complete front end rebuild on my 1985 300CD. A wee bit brain dead at this point, so reaching out for some advice.

I understand that 80Nm of torque should be applied to the 22mm nut on each steering knuckle ball joint.

Of course, as one is applying the torque, the ball joint stem/pin spins eventually and no progress is made. How to remedy this?

I was thinking that I had read somewhere that the wheel+tire must be installed and the vehicle on the ground (not on jack stands and off the ground) in order to apply the 80Nm of torque. Here's my concern: With the shock and spring installed, will there be adequate space for my torque wrench? I have my doubts about this.

And for anyone wondering: There is no hex key port in the top of the (Lemforder) ball joint stem/pin.

So, any advice as to how to hold the ball joint stem/pin from moving while applying the torque?

Thanks for any help to salvage my brain at this point.
