Frequently Asked Questions
Why should I choose Lemförder over cheaper aftermarket brands?
Lemförder (a ZF company) is an official factory supplier for Mercedes-Benz. While budget aftermarket control arms often use inferior rubber that cracks within a year or cheap ball joints that quickly develop play, Lemförder parts deliver guaranteed OEM fitment, safety, and long-term reliability.
I received two identical arms in the box. Is this correct?
Yes! Unique to the GLK-Class platform, this specific lower control arm is non-directional. The exact same part (A2043308011) is used for both the Front Left and Front Right sides. This set simply provides two of these identical arms to complete the entire axle.
Why is it important to replace both sides at the same time?
Since both sides of your vehicle carry the exact same engine weight and endure identical road impacts, they degrade at the same rate. If the left arm has failed, the right arm is likely at the end of its lifespan. Replacing both at once ensures perfectly balanced handling and saves you from having to pay for a second wheel alignment later.
Do these arms include the bushings and ball joints?
Yes. This is a complete, ready-to-bolt-on kit. The heavy-duty rubber mounting bushings and the outer steering knuckle ball joints are pre-pressed into the aluminum arms at the Lemförder factory.
