Attention! Before starting a work of the removing and installing of the control arm bushings take note of the bushing’s placement. If the placement of the bushing is significant for the proper operation, mark the correct position for the bushing in control arm. If arm has a П-shaped profile, use the strut to avoid deformation while removing and installing the bushings.

Removal 

1. Choose the metal tubings (hub base and hub driver) for the removal and installation of the bushing. O.D. of the hub driver must be 0,5 mm. less than O.D. of the outer metal shell to avoid damage of the housing bore and control arm deformation. Hub base I.D. must be 1-2 mm. bigger than O.D. of the outer shell not to interfere the removing oа the bushing.
2. Place an arm supported by the hub base on a press.
3. Place a strut into the arm if it has a П-shaped profile.
4. Place a hub driver upon the bushing.
5. Press an old bushing out of the arm increasing pressure gradually to avoid a skewness of the hub driver and deformation of the housing bore and control arm.
6. After pressing the old bushing out, inspect the surface of the housing bore, clean, file and polish if any dirt, rust, burr.

Installation

1. Compare I.D. of the housing bore and O.D. of the bushing’s outer shell. O.D. of the bushing’s outer shell must exceed I.D. of the housing bore 0,2-0,5 mm. Difference in diameters provides required fixation of the bushing in housing bore in a result of the outer shell resiliency. If you do not detect the difference in diameters, ensure the correct bushing or change the control arm.
2. If marking of old bushing was done, mark new bushing exactly as dismantled one to provide the correct position of new bushing in the housing bore of the control arm.
3. Place a control arm upon the hub base into the press.
4. Insert the strut into the П-shaped arm to avoid deformation.
5. Place new bushing in a housing bore in marked position.
6. Place a hub driver upon the bushing.
7. Start pressing. Increase the load gradually to avoid skewness and deformation of the hub driver and bushing. While pressing, take a control over the alignment of the marks on the control arm and new bushing.
8. After the new bushing is pressed in, hold the control arm and ensure the correct position of new bushing in the housing bore of the control arm.

Attention! After the bushings replacement, check the wheel alignment.
