176NM, or in English, really really tight!
It may contribute, but only slightly as it is splined, so unless the arm was wobbling about then thats not the only problem. Start with the obvious track rod ends, drop arm ball joint and steering UJs, then dont forget about wheel bearings, tyre pressures and all the other bushes around both front and rear suspension. I have also seen the screw in bracket that the sterring damper attaches to be quite wobbly.
