Car creaks when driving4/15/2023 Isolating the absorber and confirming the problem is vital. Spring absorbers may have rusted or been broken in a high impact. If they are hydraulic, then they may have air problems, oil leakage or another issue. The problem will depend on the type of absorber. If they do not work, they can lead to squeaking. Shock absorbers are part of the car's suspension. If they are faulty, the bumps will cause issues. The suspension is there to stop shocks damaging the vehicle when going over bumps or uneven ground. If any of these parts are faulty, it can lead to squeaking sounds coming from the suspension.įaulty suspension is why the car might squeak when going over bumps. The suspension is composed by many smaller parts that are connected by axles, making them difficult to access. Faulty suspension partsĪnother possible cause is that another part of your suspension is either damaged or broken, which is a more serious problem than the first. Checking your bushings regularly is helpful in preventing damage further down the line. Over time, the rubber shrinks, cracks or dries and starts squeaking whenever the suspension moves. Most rubber bushings are not lubricated and have to work dry only. If they are faulty, broken or non-existent, then the vibrations may cause damage which leads to squeaking. Rubber bushings are common on a car's suspension. If the grease gets old or leaks out, the joints can start squeaking.īushings are designed to prevent individual parts from vibrating and causing damage. Most ball joints are not lubricated externally. Ball joints are connections in which a metal ball is trapped inside in a cup lubricated with grease. They can simply drive the vehicle onto a drive on rack and try to replicate the noise by jouncing the vehicle (by hand) and using chassis ears.A squeaky sound may be caused by the connecting ball joint or rubber bushing being worn out. That’s not how that works.īrand new vehicles are disrupted at port all the time Visit a dealer and voice your concern, a brand new vehicle should have no noises and the dealer should NOT be afraid to remove or “disrupt” any parts. The car is quite new so both dealer and I are reluctant to remove/disturb factory fitted parts where possible. All plastics and fixtures have been checked by the dealer.Īnyone had this and can suggest anything else this might be. It sounds like its coming from the footwell, the door sill and the b pillar. We have driven with all the doors open and it is not a door creak. You can hear it inside the cabin but its not audible from outside (might be drowned out my engine noise). The dealer and I have both checked the trims and seals and its not from there. For this reason I have ruled out it being suspension or bushes related. You can also hear it once, when the engine turns off or starts. This creaking is also heard when the car is idle and you shift from Park to Drive or Drive to Reverse or Reverse to Drive - inline with when the load changes. It seems to come from the Right side of the car (UK drivers side) and it comes when the car is hot over uneven roads. It sounds like a suspension bush related noise but it isn't. The noise is like a mettalic creak and you can hear it on uneven roads or when going over humps. So basically I've been having this creaking noise which only happens when the car is hot and being driven for 30 minutes plus. Wondering if anyone else has experienced this with their 340i or 440i.
