Chrysler Repair: grand caravan: chassis noise when turning, zirc fitting, grease fittings

Question
QUESTION: I have a 2003 grand caravan that makes a noise when you turn (mostly right turn) that sounds like if you were making a squeeky bed noise.  are you able to grease the chasis and where are the lube points?.

thank you

ANSWER: Hi Jerry,
According to my '02 manual there are no grease fittings on the front suspension. The lower ball joint has a special fitting designed only for access by a dealer as were it a normal zirc fitting and the application of grease to that point with a pressure gun occurs the seal on the ball joint will be damaged too easily.
I wonder if the sound you are hearing is more like a clicking sound, whose frequency is proportional to the speed you are going? If that were the case then I would inspect the constant velocity joint on the outside end of the drive shaft to observe for the possibility that the flexible boot on the joint has torn and thus allowed the grease of the joint to be spun out. When that happens and the joint runs dry of grease it will begin to click, particularly when turning when the joint has to flex them most. Look behind the right wheel from a point underneath the van where you should find a ribbed boot surrounding the end of the drive shaft. See if the rubber has torn.

QUESTION: roland
thank you for answering so quickly, however the noise is definitely a squeaky type noise. It is mostly when i am barely moving as in a parking garage (which seems really loud) and am turning the wheel. If I am driving at normal speeds you don't hear anything from it. I am wondering if the brakes would have anything to do with the noise, or perhaps a spring... grabbing at straws i think..lol

thanks again

Answer
Hi Jerry,
To test the brake theory try lightly pressing on the brake pedal while the noise is present amd on-going to observe whether it changes it. It may be dust on the brake rotor or a leak of brake fluid from the caliper. Is the level of the fluid in the brake reservoir down noticeably? Is there any sign of wet streaks on the inside sidewall of the tire? The fact that you are turning may just be the result of the slight difference of position of the rotor causing it to rub on one of the brake pads and if there were dust/brake fluid on the rotor/pad that could cause the squeek.
