32 00 ... CHASSIS/WHEEL ALIGNMENT CHECK PROCEDURE

CHASSIS/WHEEL ALIGNMENT CHECK PROCEDURE STEPS

Scheme 8

32 00 ... GENERAL INFORMATION AND DEFINITIONS

Toe angle difference

a Toe angle difference

D Center point of operating circle

The toe angle difference is the angle adjustment of the inner cornering wheel relative to the outer cornering wheel when negotiating a curve. Steering is designed in such a way that angular position of wheels changes as steering lock progresses.

A correctly adjusted toe angle difference produces equal values for left and right lock with consideration of factory tolerances.

Toe angle difference provides information on corresponding operation of steering trapezoid for left or right steering lock from center position.

Scheme 9

Camber

Inclination of the wheel from the perpendicular.

Scheme 10

Toe

Reduction in distance of front of front wheels to rear of front wheels. The toe-in prevents the wheels from moving apart during driving and thus

1. the wheels from vibrating and grinding
2. excessive tire wear
3. excessive strain on the steering linkage and its links/joints
4. heavy vehicle steering

Measurement is performed in "straight-ahead mode".

Scheme 11

Caster

Is the inclination of the kingpin in the direction of travel viewed from the side. The line through the center point of the spring strut support bearing and the control arm ball joint corresponds to the "kingpin".

Thanks to caster, wheels are pulled and not pushed. In a similar manner to king pin inclination, when driving in curves or around corners, returning forces are reproduced to help return wheels to straight-ahead position.

Scheme 12

Geometrical axis 1

Is the angle bisector from the total rear-wheel toe.

Front-wheel measurements are taken in reference to this axis.

Symmetrical axis 2

Center line running through front and rear axles.

Scheme 13

Wheel offset

Angle by which one front wheel is displaced more towards front or rear than the other front wheel. The wheel offset angle is positive when the right wheel is displaced towards the front and negative when it is displaced towards the rear.

Scheme 14

Kingpin offset/scrub radius

Is the distance from the center of the wheel contact face to the intersection point of the kingpin extension. The line through the center point of the spring strut support bearing and the control arm ball joint corresponds to the "kingpin".

The scrub radius is influenced by camber, kingpin angle and wheel offset of the wheel rim.

Scheme 15

32 00 ... IDENTIFICATION OF SUSPENSION WITHOUT LABEL

Note. If the front spring strut does not have a label for suspension identification, the type of suspension can be identified from the part number in the Electronic Parts Catalogue.

32 00 ... INFORMATION ON REPLACING STEERING GEAR AFTER ACCIDENT DAMAGE

Facts

In the event of accidents or driving conditions similar to accidents, shocklike loads can cause different types of damage to steering gears. When a steering gear is externally undamaged, it is sometimes only possible to identify damage with great difficulty and with great effort. However, damage of this nature poses an unacceptable risk to the vehicle because it can result in failure of the steering system.

Because of the disproportionate amount of effort involved, it is generally not sensible to check thoroughly all the individual components of the steering gear and as an alternative it is necessary to take into account other components which can be checked more easily.

Procedure

The steering gear must be replaced if one or more of the following points apply

1. Visible or noticeable damage to the steering gear
2. Unacceptable torque increase and jamming when the steering gear is turned from lock to lock (without hydraulic assistance)
3. Permissible tolerances exceeded during axle/wheel alignment check (if necessary, include alignment record with invoice / report)
4. Fire damage
5. Damage, permanent deformation or fractures to: Wheel rims in the event of a negative result from the wheel/axle alignment check Spring struts, steering knuckles, wheel carriers Control arms Compression or tension struts or stabilizer bars with this function Body-side screwing/bolting points for wheel guide/control components Front axle carrier Pitman arms Tie rods Steering gear fixtures Steering column

This guideline is binding for all accident repairs to BMW and MINI vehicles.

Note. If the steering gear replacement work which is required for safety reasons is refused by the customer or an insurance company for cost reasons, a memorandum to that effect must be drawn up and countersigned by the party bearing the costs of the accident repair.

65 77 ... NOTES ON SCRAPPING BMW VEHICLES WITH GAS GENERATORS (CENTRAL AIRBAG CONTROL UNIT, AIRBAG SYSTEM)

The gas generator is a pyrotechnic component of

1. Airbag module Driver's/passenger airbag Side airbags Head airbag Knee airbag
2. Belt pretensioner
3. Belt buckle tensioner
4. Safety battery terminal

1 Series: E81, E87

3 Series: E46, E90, E91, E92, E93

5 Series: E60, E61 from build date 09/2005

6 Series: E63, E64 from build date 09/2005

X3: E83

X5: E53, E70

Z4: E85, E86

Gas generators that have not fired constitute a hazard (also to the environment)!

In accordance with accident prevention regulations and specific national regulations, gas generators must be rendered unusable before they are scrapped. This is necessary because pyrotechnical objects can cause injury if improperly activated (e.g. scrapping with flame cutters).

With above-mentioned vehicles which are scheduled for scrapping, it is always essential prior to draining and further stripping work to ensure that all the gas generators in the vehicle are fired. The fired gas generators can then be scrapped together with the vehicle.

Triggering failure

If correct triggering is not possible, the relevant components must (while observing the safety regulations for handling airbag system components) be removed and disposed of by special disposal companies!

If a triggering operation has failed

1. Disconnect the triggering device from the battery and
2. only approach the vehicle after a few minutes have elapsed

The components of an airbag system must always be disposed of. Such components must not be sold on as used parts.

Triggering

Triggering of the gas generators may only be carried out by expert personnel and under the supervision of a responsible person. Other standard accident prevention regulations (safety goggles, ear defenders etc.) must also be observed.

The gas generators must be fired from the outside in the vehicle scheduled for scrapping with the doors closed but with the tailgate, door windows and sunroof open. To fire the gas generators, use the BMW-developed triggering device with the corresponding cables.

1. Vehicles with central airbag control unit (all airbags, seat belt pretensioners, safety battery terminal) 1.1 Expose airbag control unit . See «65 77 016 REMOVING AND INSTALLING/REPLACING AIRBAG CONTROL UNIT»(/bmw/x5/e70-2006-2010/remont/door-locks-anti-theft-systems/#audio-navigation-anti-theft-and-restraints-repair__65-77-016-removing-and-installingreplacing) . 1.2 Connect "Airbagmaster". For subsequent procedure, refer to SEDA operating instructions.

72 00 ... SAFETY REGULATIONS FOR HANDLING COMPONENTS WITH GAS GENERATORS

It is essential to comply with the regulations as specified in the law relating to the use of explosives when working on airbag units and seat belt tensioners.

Airbags, seat belt tensioners etc. are pyrotechnical objects. Pyrotechnical objects are assigned to different danger classes on the basis of the quantity of propellant that they contain. The assignment can be ascertained from the identification marking on the product

This applies in particular to the following components

1. Airbag modules (driver's/front passenger airbags, side airbags)
2. Buckle/belt tensioner
3. Head airbag (ITS, AHPS)
4. Active knee protection
5. Active head restraint
6. Safety battery terminal (SBK)

1. Regulations The regulations quoted in the following refer to the Federal Republic of Germany. In all other countries, the relevant legislation and regulations must be observed in each case. Country-specific legal regulations that go beyond this information or court decisions based thereon must be followed in each case or given precedence over these regulations. The following components used by BMW: Pyrotechnical restraint systems are subject to danger class PT1 Gas generators are pyrotechnical objects belonging to danger class T1. Handling, transporting and storing non-fired gas generators are subject to the "Explosive Materials Act" (law relating to the use of explosives dated 13/09/1976). The relevant trade supervisory authority must be notified at least 2 weeks before pyrotechnical objects are handled for the first time. Here the relevant authority must be notified in writing of the person responsible (e.g. dealership owner, holder of general power of attorney or if necessary workshop supervisor). A certificate of qualification, i.e. specific training, is not required for the person responsible.
2. Disassembly and assembly Inspection, testing and installation work may only be carried out by expert trained personnel in BMW Service. Work on components of the airbag system should only ever be carried out with the battery disconnected, the negative terminal post covered and the plug connection of the cable leading to the gas generator disconnected. If only the battery is disconnected, the following prescribed waiting period must be observed without fail: 30 minutes for vehicles up to 9/93; 1 minute for vehicles from 9/93 In the event of breaks in work, a component with a gas generator that has been removed must be secured against access by other persons. Individual components must never be repaired. Instead, always replace them. Do not treat airbag system components with cleaning agents or grease. Components of the airbag system must not be exposed to temperatures in excess of 75°C. Airbag system components, including electronic diagnostic components, which have been dropped from heights in excess of 0.5 m must not be reinstalled in the vehicles. Before installing, subject airbag system components (including electronic diagnostic components) to a visual inspection for damage and replace if necessary. Airbag system components may only be electrically tested while they are installed and only with the BMW diagnostic system / DIS. Danger of injury: The airbag module may only be set down with the airbag itself facing upwards . Otherwise the generator will be thrown upwards if it is fired. Do not point the firing pellet of a gas generator at other persons. Components with gas generators must not be fired while they are removed. They must be disposed of by special disposal companies or returned to BMW in the packaging of the new components. When carrying out straightening and welding work with an electric welder: Disconnect battery Cover negative terminal (post) Avoid all contact with the skin when removing a fired airbag module - wear gloves. Wash with water after contact with the skin.
3. Transport Components with gas generators must be sent off in the packaging of the new components.
4. Storage Observe the regulations of the relevant trade supervisory authority and the applicable national regulations.
