"Retighten lock bolts of steering. Observe torque"

[glenmore]

This was listed as a maintenance item on the Service Sheet for W202 cars that someone was kind enough to link.

I see something similar in my 1991 300CE Maintenance Book, "15,000 miles, Retighten bolts, Steering:mounting".

How exactly do you go about this? Where are these bolts and is this a critical maintenance item or not a big deal? Can anyone supply torque values?

Thanks
