What are the symptoms of a bad lower control arm?
2 Answers
Symptoms of a bad lower control arm are as follows: 1. Abnormal tire wobbling: When the lower control arm is damaged, the vehicle's tires will wobble abnormally while driving, leading to abnormal tire wear and louder noise than usual, resulting in unstable driving. 2. Vehicle dynamic stability imbalance: Damage to the lower control arm causes the vehicle's dynamic stability to become imbalanced, and severe breakage of the lower control arm can lead to loss of control while driving and steering. The replacement method for a bad lower control arm is as follows: 1. Remove both ends of the triangular arm: Lift the vehicle, remove both ends of the triangular arm, and select two iron sleeves of corresponding sizes for the rubber bushings. 2. Remove the screws properly: Install new lower control arm bushings coated with detergent for lubrication, then reassemble in reverse order.
I know this all too well, just helped a friend deal with a similar issue recently. When the lower control arm goes bad, driving becomes a real headache. On smooth roads, the tires will clunk around like they're tap dancing, especially over speed bumps - the noise makes it sound like the car's about to fall apart. The steering wheel acts up too, secretly drifting to one side when you're trying to drive straight, forcing you to constantly correct it. The scariest part is during sharp turns when the front wheels seem to fight each other, with tires screeching like they're grinding against the pavement. Looking in the rearview mirror, you can see the outer tire getting chewed up like a saw blade. If this failure happens suddenly on the highway, it'll send chills down your spine.
