So.... preparing to swap out the shocks/struts.. making sure I have the required tools becasue.... BMW.
Firstly, the torque spec on the lower bolts is nuts!
31 31 3AZ Spring strut shock absorber to pivot mount (Replace screw & nut)
250Nm !!!
31 35 7AZ Stabilizer link on spring strut shock absorber and stabilizer (wrench surface on ball head must be parallel to absorber axle)
100Nm
31 31 1AZ Spring strut support bearing (Flanged hexagon nut dia. 21 mm - Replace nuts)
34Nm
31 31 2AZ Shock absorber piston rod on thrust bearing (Replace nut)
64Nm
Secondly, the factory spring strut shock absorber to pivot mount nut is 21mm and requires a special tool.
The Bilstein B4 uses a 22mm nut and also requires a special tool.
I have a 22mm O2 socket that fits the 22mm Bilstein nut, so the more important task of torquing this nut down correctly is good to go. Might have to make do with a 13/16" spark plug socket, allen key and ring spanner to released the old 21mm nut, where accurate torque is not an issue...
Oh and I'll have to buy a 7mm allen key too - which is at least useful for working on the brake giude pins too (and saves using a T45 Torx like I have been up until now!).
