2007 Dodge Caliber BACK end squeak. All sorts of squeaking coming from the back. Mostly over bumps. Its like a low pitch squeak. Any idea what this is?

You'll need to do a little bit of detective work. OK, When exactly does it "squeak"? Is it a short, single squeak, a stretched out long squeak or does it repeat a few times as it happens? Is it when your driving in a straight line and you hit a pot hole? Is it as you brake firmly? Is it when you take a corner at a reasonable speed? Is it when your turning the steering to full left or right?
Check your tyre pressures are all correct. Sometimes a slightly soft tyre can cause odd noises. Assuming yours has 215/60/R17 H 96 size fitted they should all be set to 32psi.

Check any rubber on your struts or any other rubber that's used for softening/dampering on the steering. I once had a piece of rubber on the front of a car that would squeak when my wife hit bumps going down our driveway, drive my wife crazy and since it was under warranty we made the stealership find and repair it. Only took about 5 trips to stealership before the clowns finally found it.

well it can still be anything, locating a steering/suspension noise can be hard. Based on what you typed, what first comes to mind is the steering pump is worn out. If it is more of a low whining sound instead of squeaking, its probably the steering pump.

The noise would usually be the strut or the control arm bushings. The vibration could also be the component making the noise, or warped brake rotors.

Sounds like wheel bearing going out.




Performance Air Intakes

noises are a pig to diagnose from afar but i would get a can of spray silicon and spray one component at a time to find the noise...do it when dry and when you dont hear it guess what?.....

that model year had issues with ball joints i have replaced lots for the squeeking

Have you checked the metal clips that olds the brake pads in the front galiper bracket. They usualy rust, break loose and come in contact whit the disc, creating a squeaking noise. Those should be replace since they are needed for the brakes to work properly

sounds like the lower ball joint is making noise.

Get a friend to turn wheel back and forth in the garage, get on the ground and use your hands to feel where the noise is coming from. Metal gives off a significant amount of vibrations with noise. Should be easy to tell where it's coming from. Could be your rack and pinion, however I would be much more willing to consider ball joints. Hard to tell without getting "down and dirty" on the floor under the vehicle feeling for the noise.

Could be your steering gearbox, tierod end, rack and pinion piston, low power steering fluid, bad serp belt, ball joints, front struts/mounting hardware.

Also test steering with the entire vehicle on the floor and with the front end off the ground lifted by a few floor jacks lifting on the frame of the vehicle.

Ball joints especially on Ford vehicles tend to squeak after a while (mostly since they are the sealed type) even if they pass a safety inspection.
