It is necessary to replace the lower control arm with an OEM part. Material differs from OEM: The main issue with poor-quality lower control arms is that the material differs from the OEM, which can affect driving safety. For example, if the vehicle hits a rock, an OEM control arm might bend but still allow steering control to move the vehicle to a safe location; a low-quality control arm might break directly. Cracks in the lower control arm bushings can cause a loose chassis: If the lower control arm bushings develop cracks or even completely break, the driver may experience a loose chassis and abnormal noises while driving. Over time, aging and damage become almost inevitable.
I've been repairing cars for over 20 years and have seen too many problems caused by not using OEM lower arms. I strongly recommend you always use genuine parts. OEM components precisely match in material and dimensions, undergo comprehensive testing before leaving the factory, ensuring suspension stability without wobbling during high-speed cornering. Aftermarket parts might be cheaper, but they often cut corners - prone to rust, deformation, and worst case scenario, breakage causing accidents. Safety should always come first; don't gamble with your life over small savings. Regular lower arm inspections are crucial - replace immediately with OEM parts if you notice wear or abnormal noises. Have them installed at authorized 4S shops to guarantee warranty coverage. Remember, quality vehicles start with details - OEM parts offer superior durability, saving you future headaches.
As an average person with a family car that's been driven for years and a limited budget, the lower control arm doesn't necessarily have to be replaced with an original part. There are plenty of aftermarket options available, and choosing well-known brands like certified OEM products can offer good quality at half the price, lasting three to five years without issues. The key is to pick reliable channels, checking user reviews and warranty policies. If the car is still new or under warranty, going with original parts is safer; for older cars or just daily commuting, aftermarket parts are sufficient. However, avoid the cheapest no-name brands to prevent poor quality causing abnormal suspension wear and increased repair costs. Balancing expenses and risks, my experience suggests testing the fitment of aftermarket parts before installation to ensure smooth and stable driving without looseness.
