After removing the bumper, access to the side members and attachment points of the trailer hitch opens. It is important here to clean the surface of dirt and rust before applying the anti-corrosion compound.

Installation of the beam is carried out with an assistant, since the structure is heavy and inconvenient to hold with one hand. The bolts are inserted into the technological holes, and the nuts are tightened with a certain force. Use a torque wrench to avoid stripping threads in aluminum or steel bodywork. Tightening torque usually 60-80 Nm, but for exact data, see the instructions for the specific towbar.

After mechanical installation, the bumper is installed in place. If the towbar is removable, the locking mechanism should operate smoothly without jamming. Make sure that the bumper does not touch the metal elements of the towbar, otherwise vibrations and extraneous noise will occur when driving. All cracks must be closed with decorative plugs.

• Use a torque wrench to properly tighten bolts
• Cleaning and degreasing of the mounting area is mandatory before installation.
• Checking the gaps between the bumper and the towbar will prevent damage

What to do if the bumper does not fit into place?
