Tow hitch, fixed
Preparations
- Remove the four screws in the rear edge of the rear wheel housings on the right and left-hand sides.
- Remove the two screws in the lower edge of the bumper cover.
- Pull out the corner and continue to pull the bumper cover away backwards until the five clips at the side and under the rear lamp have released.
- Repeat the operation on the other side.
- Remove the bumper cover by pulling it backwards until the three catches opposite the tailgate opening have released.
- Remove the connector for park assistance if applicable.
- Detach the connector and cable from the shock-absorbing section above the impact member.
- Remove the screws and remove the shock-absorbing section above the impact member.
- Remove the screws and remove the impact member.
Applies to cars with twin rear silencers.
- Remove the screws in the rear mountings on the right and left-hand sides of the silencers and lower them down to the stop.
Applies to cars with single rear silencer
- Remove the screw in the rear mounting on the left-hand side of the silencer and lower down to the stop.
Applies to cars with twin rear silencers.
- Remove the clips to the heat deflector plate on the right and left-hand sides and fold it down toward the silencer so that the holes on the inside of the rear side members are accessible.
Applies to cars with single rear silencer
- Remove the clips to the heat deflector plate on the left-hand side and fold it down toward the silencer so that the holes on the inside of the rear side member are accessible.
Illustration A applies to vehicles with 8 cylinders, 6 cylinders and four wheel drive
Illustration B applies to other variants
- Detach the exhaust system rubber mounting in the body behind the centre silencer by the fuel tank.
Applies to all models
- Detach the exhaust system rubber mounting in the body above the front edge of the subframe.
- Now angle the silencer and radiation shield down to gain optimum accessibility to the holes for the towing member's mounting.
- Measure out a distance of 70 mm (2.75") from the centre in the embossing on the insides of the side members and backwards on the protective tape covering the mounting holes for the towing member.
- Cut off the protective tape and discard the long rear section.
Installing the towing member
- Thoroughly clean away splashes of underseal, putty or dirt from the plate surfaces on the insides of the side members where the reinforcements shall be located.
- Check that the contact surfaces inside the side members are clean, if not, clean them opposite where the towing member's side plates shall be tightened.
- Take the towing member from the kit and insert the two side plates in the holes in the rear edge of the side members.
- Take screws and the reinforcement bar from the kit. Get assistance to hold and adjust the position of the towing member when the screws are tightened into the towing member's weld nuts. The silencer and deflector plate need to be pressed down to allow the screws and reinforcement bar to be positioned and torque tightened.
- Tighten the screws alternately on both sides.
Tightening the screwed joint
- Tighten the screws to 90 Nm (66.5 lbft.) and angle tighten to 60°.
When angle tightening screwed joints in a confined spaces, a protractor, applied to the torque wrench, cannot be used. An Allen screw head is used to determine the turning angle instead.
- Make a mark on the flange of the screw head (1).
- Make a second mark (2) on the reinforcement bar.
- Now tighten the screw so that the screw head marking (1) lines up with the marking (2) on the reinforcement bar.
- Repeat for all screws.
Applies to cars with twin rear silencers.
- Reinstall the heat deflector plate and the rear mountings for the silencers. Torque tighten the mounting screws to 50 Nm (37 llbft.).
- Carry out the equivalent operation on the left-hand side for cars with single rear silencer.
Illustration A
Applies to all models
- Reinstall the exhaust system rubber mounting in the body above the front edge of the subframe.
Illustration A applies to vehicles with 8 cylinders, 6 cylinders and four wheel drive
Illustration B applies to other variants
- Reinstall the exhaust system rubber mounting in the body behind the centre silencer/by the fuel tank.
Applies to all models
- Apply rustproofing agent P/N 1161682 on the marked clean plate surfaces on the impact member and rear edge of the rear side members on the left and right-hand sides.
- Reinstall the impact member and tighten the screws to 48 Nm (35.5 lb.ft.).
- Reinstall the shock-absorbing section above the impact member and tighten it in using the existing screws.
- Reinstall the connector and cable to the shock-absorbing section above the impact member.
- Apply tape to the outside of the bumper cover, opposite the markings on the inside and right up to the first joint line on the lower section of the bumper cover. This is in order to protect the paintwork from the base of the saw when sawing out the cut-out for the towbar.
- Cut out the cut-out following the existing markings.
Note! Do not damage the painted surface of the bumper cover. Cut so that the raised edge on the inside remains. The raised edge marks the cut-out.
- Smooth off the sawn edges with a fine toothed file.
Note! Install the towbar connector with wiring in accordance with the applicable installation instructions before reinstalling the bumper cover.
- Reinstall the bumper cover and the connector for park assistance if applicable, ensure that all catches engage.
- Tighten the end faces of the bumper cover into the wing liners using the existing screws.
- Tighten in the bumper cover at the lower edge using the existing plastic nuts.
- Remove the protective paper from the bumper cover.
