Removal

 PERFORMANCE ORDER

  1. Merge oil from back differential (see the Head the Current leaving and service).
  2. Separate the driveshaft from a connecting flange of the leading gear wheel of the main transfer and tie up it to a frame.
  3. Give nuts of fastening of the lower support of shock-absorbers (7).
  4. Weaken (but do not turn out) bolts (1 and 2) of fastening of a diagonal bar (3) to the back bridge and to a frame.
  5. Disconnect and muffle (9) brake lines filled in the holder, and also the hydraulic line (10) of the drive of blocking of back differential.
  6. Disunite the socket (4) electrical wirings on the executive cylinder of the drive of blocking of back differential.
  7. Having disconnected from the body party, remove back wheel ABS sensors (see the Head Tormoznaya and auxiliary systems).
  8. Connect an electrical wiring of sensors from the side of the bridge.
  9. Disconnect from the lever and remove, having passed through floor panels, cables of the drive of the parking brake (see the Head Tormoznaya and auxiliary systems).
  10. On the models which are not equipped with system of distribution of brake efforts (EBV) disconnect draft (5) of the automatic regulator of brake pressure.
  11. Release cables of the drive of the parking brake from intermediate clamps on longitudinal levers of a suspension bracket (6).
  12. Hang out the car so that it was possible to remove screw springs (8) (see the Section Removal and installation of springs of a forward suspension bracket).
  13. Turn out a bolt (1) of fastening of a diagonal bar (3), then give assembly of the bridge back and take it from under the car.
  14. Otboltite from the bridge longitudinal levers (6).
