3 Remove right or left camber strut When replacing elastomer bearing (2) of camber strut  
AR35.20-P-0110NKB 
4 Position threaded spindle (01) with thrust nut (02), hollow-piston cylinder (003), sleeve (03) and thrust piece (04) on wheel carrier (1) and elastomer bearing (2) SPECIAL TOOL Hollow piston cylinder Figure
SPECIAL TOOL Hand pump Figure
SPECIAL TOOL Hydraulic hose (complete) Figure
SPECIAL TOOL Extraction and insertion tool Figure
5 Press elastomer bearing (2) out of wheel carrier (1) IMPORTANT The hollow-piston cylinder (003) must be relieved several times using the hand pump. When doing so the threaded spindle (01) has to be adjusted using the thrust nut (02) and the hollow-piston cylinder (003) actuated again.  
INSTALLING Install     
6 Position threaded spindle (01) with thrust nut (02), hollow-piston cylinder (003) and sleeve (03) on wheel carrier (1) and mount elastomer bearing (2) with thrust piece (04) on threaded spindle (01) NOTES Note chamfer on wheel carrier (1). When pressing in, the elastomer bearing (2) must be positioned at the chamfer side of the wheel carrier (1) and pressed in.
The elastomer bearing (2) and, possibly, the wheel carrier (1) can otherwise be damaged.

7 Press elastomer bearing (2) uniformly into wheel carrier (1) IMPORTANT The hollow-piston cylinder (003) must be relieved several times using the hand pump. When doing so the threaded spindle (01) has to be adjusted using the thrust nut (02) and the hollow-piston cylinder (003) actuated again.
IMPORTANT When pressing in, the press-in dimension (A) between the wheel carrier (1) and elastomer bearing (2) has to be checked.
