Find the strut mount bolts connecting the strut to the suspension. Use the socket wrench to unscrew these bolts.
6. Compress the Spring
Safe the strut in a coil spring compressor. Make sure the compressor is correctly positioned to compress the spring safely and successfully. Slowly and progressively compress the spring, taking care to deal with it with warning because it incorporates excessive ranges of power.
| Warning | Security First |
|---|---|
| By no means try to compress a spring with out a designated spring compressor | All the time put on acceptable security gear and deal with the spring with care |
7. Take away the Prime Strut Nut
As soon as the spring is compressed, use the affect wrench to take away the highest strut nut. This releases the strut from its mount.
8. Fastidiously Take away the Strut
Slowly information the strut out of its housing. Take warning to not harm the spring or different surrounding parts.
Putting in the New Struts
7. Getting ready the Struts for Set up
a. Take away the manufacturing facility plastic trim masking the highest of the strut.
b. Disconnect {the electrical} connections to the strut mount.
c. Use a 21mm socket or wrench to take away the 2 bolts securing the strut to the knuckle.
d. Loosen the three bolts holding the strut mount to the strut tower, however don’t take away them utterly.
e. Place a flooring jack below the management arm and lift the automobile barely to alleviate strain on the strut mount.
f. Take away the three bolts utterly and separate the strut mount from the strut tower.
g. Switch the higher strut mount and bearings from the outdated strut to the brand new one.
h. Compress the brand new strut utilizing a strut compressor instrument or a hydraulic press (discuss with the producer’s directions for correct compression methods).
i. Apply a skinny layer of anti-seize to the strut shaft and insert it into the knuckle.
| Step | Motion |
|---|---|
| 1 | Take away plastic trim |
| 2 | Disconnect electrical connections |
| 3 | Take away strut bolts |
| 4 | Loosen strut mount bolts |
| 5 | Elevate automobile and take away strut mount bolts |
| 6 | Switch higher strut mount |
| 7 | Compress new strut |
| 8 | Apply anti-seize and insert strut |
Reassembling the Suspension Parts
Now that the brand new struts are in place, it is time to reassemble the suspension parts. This course of is actually the reverse of the disassembly course of, however there are some things to bear in mind.
First, be sure that the entire parts are clear and freed from particles. This may assist to make sure a correct match and stop untimely put on.
Second, use a torque wrench to tighten the entire bolts and nuts to the desired torque. This may assist to make sure that the suspension is correctly assembled and secure to drive on.
8. Putting in the Caliper Provider
Set up the caliper provider to the steering knuckle. Use the 21 mm socket to tighten the two bolts to 110 Nm (81 ft-lb).
Set up the brake rotor to the wheel hub. Use the 18 mm socket to tighten the two bolts to 140 Nm (103 ft-lb).
Set up the caliper to the caliper provider. Use the 13 mm socket to tighten the two bolts to 24 Nm (18 ft-lb).
| Description | Torque |
|---|---|
| Steering knuckle to caliper provider | 110 Nm (81 ft-lb) |
| Wheel hub to brake rotor | 140 Nm (103 ft-lb) |
| Caliper provider to caliper | 24 Nm (18 ft-lb) |
Reattaching the Brake Traces and Sensors
After including the struts and different parts again into place, it’s time to reattach the brake strains and sensors.
- Find the brake strains. The brake strains are sometimes manufactured from metallic and run from the grasp cylinder to the brake calipers. They are often recognized by the rubber hoses that join them to the calipers.
- Disconnect the brake strains. Use a wrench to loosen the bolts that safe the brake strains to the calipers. Watch out to not harm the brake strains or the bolts.
- Take away the sensors. The sensors are small, spherical gadgets which might be connected to the brake strains. They are often eliminated by hand or with a small wrench.
- Examine the brake strains and sensors. Search for any indicators of harm, reminiscent of cracks or leaks. In the event you discover any harm, substitute the brake strains or sensors.
- Clear the brake strains and sensors. Use a clear fabric to wipe away any filth or particles from the brake strains and sensors.
- Apply brake grease. Apply a skinny layer of brake grease to the brake strains and sensors. This may assist to stop corrosion and guarantee an excellent seal.
- Reattach the sensors. Hand-tighten the sensors onto the brake strains. Don’t overtighten the sensors, as this might harm them.
- Reattach the brake strains. Tighten the bolts that safe the brake strains to the calipers. Don’t overtighten the bolts, as this might harm the brake strains or the calipers.
- Bleed the brakes. Bleeding the brakes is a strategy of eradicating air from the brake strains. This should be achieved after any work is carried out on the brake system.
To bleed the brakes, observe these steps:
- Open the bleeder valve on the caliper furthest from the grasp cylinder.
- Have an assistant pump the brake pedal a number of occasions.
- Shut the bleeder valve.
- Repeat this course of for every caliper, beginning with the caliper furthest from the grasp cylinder and dealing your technique to the caliper closest to the grasp cylinder.
Tightening and Torquing Specs
To make sure correct performance and security, adhere to the next tightening and torquing specs:
| Part | Tightening Torque |
|---|---|
| Strut to Knuckle Bolts | 47 ft-lbs |
| Sway Bar Finish Hyperlinks | 22 ft-lbs |
| Strut Mount to Physique Bolts | 18 ft-lbs |
| Strut Prime Nut | 51 ft-lbs |
| Wheel Lug Nuts | 89 ft-lbs |
It’s essential to make use of a torque wrench to attain these exact specs. Tightening the nuts and bolts too loosely can compromise the strut’s efficiency and security, whereas overtightening can harm the parts.
All the time discuss with the automobile’s service handbook or seek the advice of a professional mechanic for particular directions and security precautions associated to your particular BMW mannequin.
Ignoring these tightening and torquing specs can result in untimely put on and tear, lowered efficiency, and even potential security hazards. By following these pointers, you may make sure that the strut substitute is finished appropriately and your BMW operates safely and effectively.
