One of the lesser known components of the suspension system, the Nissan Pathfinder link bushings are there to help prevent your vehicle from swaying back and forth while turning. Even though they are only minor parts of the system, without them, the sway bar will not be able to function properly. Should you experience the following symptoms, perhaps you should give the link bushings a check-up.
When you hear a rattling or clunking noise from the rear end of your SUV whenever you drive at low speeds, then its link bushings might already be worn out. Because this has been a common problem with many cars, it is recommended that you replace the faulty components with an aftermarket set. If you buy an OEM product, you might increase the risk of encountering this problem again. You could also consider replacing the strut assembly to address the problem.
If the link bushings go bad, the entire sway bar would move up and down. If you hit a bump or take a turn too hard in this condition, you may hear a loud thumping noise from the front end. This sound is most likely to come from the sway bar hitting the mounting bracket where the bushing used to insulate. The loudness of the thumping noise will depend on the intensity of the bump or turn. Repairing this will be more difficult as you also need to fix the sway bar.
If your tires have been wearing out irregularly and prematurely, check the link bushings to see if they have cracked. If these get damaged, they can cause an excessive movement in the suspension. Do not just replace the affected tire; it is better to replace the link bushings first as they will just cause the same damage to the new tire.
Inspect the sway bar and link bushings to see if they are dented or bent. Look for signs of damage or wear on all the other parts. Make sure that the link bushings are not brittle or torn.
Look for deterioration in them as well. See if the components that the link bushings are attached to still fit tightly; otherwise, replace them. Unscrew the nuts holding the bushings and see if the components need to be replaced. Check the rest of the suspension system to see if any of them are damaged or worn.
