Sc 430 2002 front end banging noise going over bumps

The acadia has two common problems for front end noises. You likely have worn lower control arm bushings. You will need both front lower control arm bushings. Also it is common for the struts to wear out from about 75k miles up. If they are leaking or have a harsh ride you should replace those as well.

It sounds as though something is loose, probably in the front end. Check, or have a shop check the front end components or for any loose body parts that could be causing the nose. I hope this helps.

This is a hard problem to describe, I know, and I will toss out a few possibilities. If the noise occurs when the car is accelerating, it can be motor mounts, or carriage mounts on front-wheel drive vehicles. Transmissions can bang into gear. Drive shaft u-joints can bang before they fail. C-V joints in front wheel or 4 wheel drive units can bang when worn out.

The exhaust system can break loose and bang on the frame. Brake calipers can rock in their mounts and transmit sound. Tie-rod ends can make a knocking noise on every bump you hit. There were recalls on gas tank straps for some Ford made units, so a loose gas tank can bang.

when do you hear the noise? is it a rattle over bumps? does it stop when brakes are applied? ck sway bar bushings, are they good

sounds like a blown strut or a bad strut tower

hi, the most likely cause of the noise is going to be the bottom ball joint or the anti roll bar bushes if you only get the noise when going over pot holes or bumps then the chances are its the bottom ball joint but if the noise is their whilst on even road or slight bumps then this would point towards roll bar bushes, getting them replaced will stop the falling apart and giving you a banging noise

could be your front lower control arm bushings. they are notorious for failing.

Is the coil spring binding from a bad strut mount bearing?

this problem usually occurs when your cv joints are wearing thin or depending wether it is a loud thumping noise could be your wishbone bushes which if so wil ned replacing.

ON MINE IT WAS THE WISH BONE BUSHES, CHANGED ALL WITH THE POLYUATHANE DONE THE JOB
