Removal and installation the front bumper (BMW 5 Series E34)

The design of the front bumper is such that collisions at speeds of up to 4 km/h do not cause any damage. The collision energy is absorbed by an aluminum beam located inside and two hydraulic shock absorbers. The shock absorbers are mounted on two easily replaceable deformation elements, the so-called shock boxes. At collision speeds of up to 15 km/h, energy absorption occurs due to the deformation of hydraulic dampers and shock boxes without causing damage to the engine beam.

Removal

Hook the left and right bumper covers near the license plate and pull them outward.



Pull the wheel arch liners behind the bumper.



Unscrew the 4 "arrow" nuts and pull the bumper forward.





If equipped, disconnect the fog light connector and disconnect the headlight washer hoses. Clamp the hoses to prevent fluid from leaking.



Remove the fastening plugs, remove the trim from the aluminum beam.

Installation

Assemble the bumper.

Install the bumper. Connect the headlight washer hoses, connect the fog light connectors.

Insert the bumper into the side guides and press.

(Figure W— 4869) The distance A between the bumper and the body should be up to 6 mm, apply a gasket and align if necessary. In this position, tighten the 4 bolts "arrows" with a torque of 45 Nm.



If necessary, align the bumper flush with the body. To do this, turn the threaded sleeve with a screwdriver (narrow outer ring), holding the inner cover with a second screwdriver. At service stations, the BMW 51 1040 device is used for this purpose.



First hook the bumper pads on the sides and then snap them into place.
