What is a lateral link?
Lateral links are used in the rear end suspension, and play an important part in keeping your rear wheels aligned by providing support to the rear axle. While most modern cars and SUVs focus on front suspension, the rear is just as important. Without a functioning lateral link, the rear hub assemblies can’t connect to the middle of the car body to keep the rear hubs centered, leading to faulty steering amongst other handling complications.
When should I replace the lateral link on my car?
A faulty lateral link needs to be replaced immediately, as leaving it can result in further damage and an unreliable driving experience. Common symptoms of a malfunctioning lateral link are:
Wobbling sensations/loose steering: Lateral links and bars provide extra weight on the rear tires so they remain secure and stable. However, if a lateral link is failing, this pressure will lessen, leading to a wobbling sensation or loose steering.
Clunking sounds: Sometimes with a faulty lateral link, you can hear clunking noises from the back end of your car. As bushings or support joints attached to the lateral link begin to wear, it creates sound each time you hit a bump or pothole in the road. In more severe cases, the lateral link can fall off and drag on the ground, creating additional noise.
Increased wear on tires: While the rear lateral links provide pressure, they don’t increase the wear and tear on your tires—but a failing one might, due to reduced weight applied to the inner and outer edges of the vehicle.
How often should a lateral link be replaced?
Lateral links are designed to last the lifetime of your vehicle, but rarely meet that quota. Due to increased stress and heat from your car, they can become weak and may need to be replaced every so often. A non-functioning lateral link can affect your entire suspension system, and lead to an increased risk of accident.
Can I replace a lateral link myself?
Yes. A lateral link replacement can be completed at home, if you are comfortable with your DIY skills and knowledge of car parts. Lateral links can be removed and replaced in 7 steps, however, if you are unsure of your ability to complete it, it’s best to visit a licensed mechanic.
