Does the BMW 740 require matching when replacing rear shock absorbers?
2 Answers
BMW 740 does not require matching when replacing rear shock absorbers. Open the front engine hood: There is a bolt on top of the shock absorber used to secure the shock absorber piston rod. Remove the front wheels, and there are two bolts on the brake disc used to secure the lower bracket of the shock absorber. Generally, there are also two small nuts securing the hose bracket and stabilizer bar bracket, which can be removed. Lift the vehicle: Lift the vehicle until all four wheels are off the ground. Debris causing oil seal wear: The internal cleanliness of the shock absorber is poor, with welding slag, iron filings, and other debris causing oil seal wear. Reinstall the new shock absorber: Reinstall the new car shock absorber.
I've been into cars for many years and have driven quite a few BMWs, including luxury models like the 740. When replacing rear shock absorbers, it's not just a simple removal and installation job, especially for high-end BMW models. Some versions of the BMW 740 come with an Electronic Damping Control (EDC) system, which manages the shocks using sensors and an electronic control unit. If the system isn't properly matched after installing new shocks, the car might display warning lights, and the driving experience could become unstable—like being too soft or too hard when cornering. I believe it's best to use a diagnostic tool to reprogram the system, ensuring the new parts sync with the car's original ECU. Usually, authorized dealerships can handle this, but if you're getting it done at an independent shop, make sure they're familiar with BMW's diagnostic system. Don't skip this step—proper matching makes the ride much smoother. Also, if the car is older, worn-out shocks might even affect the suspension geometry. Safety first, after all. In short, consulting a professional is the safest bet—don't risk big problems to save a little.
