Fig. 1 Pressing out front bearing -A- for upper control arm

Fig. 2 Pressing in front bearing for upper control arm
^ Press in far enough so that the collar of the bearing projects out evenly on both sides.

Note: Before pressing in, coat using lubricant, e.g. lubricating soap.





Fig. 3 Rear bearing for upper control arm, pressing out and pressing in
^ Press in far enough so that the collar of the bearing projects out evenly on both sides.

Note: Before pressing in, coat using lubricant, e.g. lubricating soap.





Fig. 4 Remove rubber collar from bonded rubber bushing -1-

Fig. 5 Bend up metal collar -1- in area -a-





Fig. 6 Pressing out front bearing for lower control arm





Fig. 7 Pressing in front bearing for lower control arm
^ Press in bearing up to stop.





Fig. 8 Re-pressing in front bearing for lower control arm
The larger inner diameter of 2010 sleeve points toward control arm.
^ Insert a bolt -A- into bearing for repressing (e.g. 10-203).
^ Re-press until the rubber collar jumps out from the control arm.





Fig. 9 Pressing out rear bonded rubber bushing from lower control arm
^ Mark installation position beforehand, e.g. via a punch indentation go to Fig. 10, arrow B.





Fig. 10 Installation or rear bonded rubber bushings
Bonded rubber bushing must be pressed in so that the lug (arrow A) points upward and is offset by 11 to symmetrical axis of control arm (left and right).

Note: Control arm must be held in installation position to do so.





Fig. 11 Pre-tension rear bonded rubber bushing for lower control arm
^ Next, pre-tension bonded rubber bushings using hose clamps as seen in illustration, until both metal shells of the bearing contact each other (arrow).





Fig. 12 Press in rear bonded rubber bushing into lower control arm
^ Press in pre-tensioned bonded rubber bushings (go to Fig. 11) in installation position (go to Fig. 10) far enough so that a distance of 371 ± 1 mm is created between inner tube of front bonded rubber bushing and inner tube of rear bonded rubber bushing go to Fig. 13.





Fig. 13 Installation measurement of bonded rubber bushing of lower control arm
Dimension a go to 371 ± 1 mm

Fig. 14 Press off coupling rod from stabilizer (23.5 mm)
Coat rubber bushing of coupling rod at inner radius with lubricant, e.g. lubricating soap and press coupling rod off of stabilizer.





Fig. 15 Unbolt and bolt on coupling rod at stabilizer (27 mm )
1 - Reinforced stabilizer 27 mm | 2 -coupling rod
