Those are the noises my car makes as I travel down the road in very cold temps, anyone else experience this?
It has done it since brand new, and has never been wrecked. I have driven other cars in the same weather conditions, even older than mine, and they don't do it. Also my washer nozzles constantly get clogged up being on the wiper arm. I guess my j hates the cold.

Ive got 01 cavalier 2.2L auto, its got 157,000kms on it. Also rattles viberates here and there, Ive owned 6 cavaliers now, They have all been great cars. Ive really enjoyed the V6 models, But I Enjoy 3rd Gens. Anwser to youre question, I believe its normal sounds from these Cars. The pop sound could suspension related, How many miles on youre car?. For youre window wash nozzle lines they always get frozen with ice, Depends on how cold it gets in Area. My Friend re routed his washer lines from his vent area under the front panel near the windshield, Works great added some bigger rubber lines more washer fluid comes out, The only way to make sure youre lines dont get frozen, Depends on youre washer fluid.

Good Luck.
