What would cause an 05 liberty to start rattling and squeaking when it warms up

the squeaking sounds like a wheel bearing going bad. And the pulling to one side is cause by unequal braking pressure caused by plugged rubber brake hose, bad calipers or wheel cylinders. Check the bearings by lifting the car with a jack, block the wheels, and use a jack stand for safety. now wiggle the tire around. If it has any play, the bearing is bad. Replace it. I would replace your brakes as well. Good luck

test the front end completely. You must go to the mechanic, the tires specifications you must see

God bless you

I take it by you saying part-time light your refering to the 4 wheel drive??? Take it to Auto Zone and have them run the codes (its free) They will tell you if something is causing it.

Sounds like a throw out bearing on the clutch

Usually squeaks are rubber bushings that need liquid soap lubrication. The anti-roll bar bushings and end links are common sources. So is the lower arm bushings that work with the strut assembly. Suggest getting under the car while someone pushes down on the front end to get it squeaking. Good luck!

squeaks,rattles hard to diagnose from afar but have you tried wd40 on one rubber bush at a time until squeaking stops,when it does,youve found it.....

one thing you didn't mention is if the dealer replaced the caliper hardware. take alook at this:

Could be the door panel rattling around.
the main other squeak culprit in these models is the latch and pin that locks the rear seats upright. If these get slightly worn or are not properly and tightly adjusted, they can cause the most annoying squeak! Easy to check this one. just fold seats down and drive and see if the noise goes.
it would be better if you tied electrical tape around the latch.

check motor mounts defective ones can cause engine to vibrate
