Removal and installation of the control arm bushings without outer metal shell.


Attention! Before starting a  work of the removing and installing of the control arm bushings without outer metal shell, choose the metal tubings (hub base and hub driver) for the removal and installation of bushing. O.D. of the hub driver must be the same as O.D. of the inner metal sleeve. Hub base I.D. must be 1-2 mm. bigger than O.D. of the bushing’s flange not to interfere the removing of the bushing. Forcing should be applied to the inner metal sleeve.

  1. Place an arm on a press, supported by the hub base (fig.1).
  2. Place a hub driver upon the bushing.
  3. 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. Avoid damages of the housing bore.
  4. After pressing the old bushing out, inspect the surface of the housing bore, clean, file and polish if any dirt, rust, burr.


Attention! Control arm bushing without outer metal shell is recommended to be pressed through the taper. During the pressing in, the forcing must be applied by the hub driver to the inner metal sleeve.

  1. Lubricate the taper inside, housing bore in the arm, outer surface of the bushing with supplied grease or any other consistent grease.
  2. Place a control arm upon the hub base into the press (fig. 2).
  3. Place a taper upon the housing bore.
  4. Place a new bushing into the taper.
  5. Place a hub driver upon the inner metal sleeve of the bushing.
  6. Start pressing. Increase the load gradually to make bushing spreading evenly until it fills the housing bore completely.
  7. Initially the bushing may slip into the housing bore slightly skewed because of the difference in diameters of the hub driver, housing bore and bushing. Due to the resiliency of the bushing, it’s bigger diameter allows to fill the housing bore completely and fix the bushing properly.
  8. After the new bushing is pressed in, remove excess grease. Check the symmetry of the bushing’s placement and tightness of flanges to the housing bore. If necessary, align the bushing in the housing bore.

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

Possible problems*   *Are not a result of the parts defects and can’t be considered as a warranty caseInner metal sleeve is torn off.Control arm bushing without outer metal shell doesn’t slip into the housing bore because of the bulging elastomer.Bushing is not holding in the housing bore.
