Adjusting left or right front door BMW 3 E46

41 51 004 

Note:

Doors are fitted and bolted to an unfinished body shell.

Moving the hinges later on makes unpainted surfaces visible. These surfaces must be touched up with paint in the body color.

Note:

These adjusting instructions generally apply to all body variations such as Saloon/Sedan, Coupé, Compact, Touring, Cabrio/Convertible.

On 4-door models, it is important to align the rear doors first.

The reason for this is that the rear doors must be aligned to the welded rear side walls.

The front doors must then be aligned to the rear doors.

The bolted front side walls can then be adapted if necessary to the front doors.

On 2-door models, the doors are aligned to the welded rear side walls.

The bolted front side walls can then be adapted if necessary to the doors.

The illustrations therefore do not always correspond to the type of vehicle selected in the TIS.

The illustrations are therefore to be viewed as basic illustrations which are to be carried over to the relevant vehicle type.

Caution!

Slight corrections by straightening are permitted if the existing adjustment options are insufficient.

Extensive straightening would lead to the doors becoming “soft” and cause them to lose their tension on a long term basis. At high road speed and with strong side wind, the door frame could then lift off of the hose seal.

Note:

Keep to the sequence of procedures for correct alignment of doors. Before installation, assemble doors with window lifter and glass.

Door settling behavior depends on weight!
