Does anyone’s 2017 Mitsubishi Triton GLS suspension squeak loudly. If so why?
Squeaking when a car’s suspension moves up and down is usually down to a couple of things. Either there’s wear in a ball-joint or suspension bush, or the bushes and joints are full of dry dust. Have you driven the Triton off-road in sand or dust recently? You might find that some dust has managed to work its way into the rubber bushings and is causing the noise.
At worst, you may have damage to something in the suspension that is placing a load where it shouldn’t or perhaps even rubbing where it shouldn’t. With the vehicle securely parked, you can climb underneath and have a friend use their body weight to bounce the vehicle on the spot. If you’re lucky, you might be able to pin-point the source of the squeak.
