Steering not self centering

Is it definitely 10, or could it be 12? If the latter it probably requires a spline bit (a.k.a. triple-square bit) - common on VAG group cars.

It is 10 point, just been out to look at a spare rack I have in the garage. Size wise, see what you can work out from the photos. I'd be interested to hear what happens if it's loosened.

My aim is to get some grease into the rack. I can get some in at the ends, and hoping to get some in at this point. I can not see it being any different inside than any other BMW steering rack.
If I could get the plastic plug out without damaging it, then I could get some in there.

I reckon a piece of rectangular bar, 17mm x 22mm would fit the spline very well. It shouldn't be very tight. Will see what i can get hold off at work.

I was thinking a decent size bolt head would likely engage it well enough, then just turn the bolt shaft with mole grips!

I have just modeled the spline with different shapes, and a 22mm or 24mm hex just wont fit it!
I am going to make a tool to fit it. five 5mm pins on a 23.3pcd should be a good fit.

drill and tap 5 holes for 5mm bolts on pcd 23.3mm into a 5mm thick flat bar
