is it because rubber acts differently in cold weather than in warmer weather?
Only rear wheel drive vehicles have rear axel (differential) fluid. It's not AS critical as the engine oil, but you should change it about once per year. Normally cars only have a fill plug. To drain to fluid you'll have to either remove the rear cover and let it drain out then reinstall the cover with a new gasket, or suck the fluid out throught the fill plug hole. You can have this done at one of the many auto lube centers like Jiffy Lube for about $20. Changing the fluid annualy will increase the life of your rear axel/differential which costs about $1200 to rebuild/replace.
It isn't fluid it is cld 90w gear oil and it needs to be replaced per your owners manual or cars service interval book that u may or may not have and if not it is in a repair manual u get autozone. It does need replaced sometimes but 99% of the time you will just have to refill it to the plug in the rear end till u can feel the fluid touch the tip of your finger. there is a plug you take out to feel for the level and fill it and it is normaly the same plug.
Cars have steel belts bikes don't.
Yes, I think you're right, rubber is harder when it's colder, and softer when it's hot out, although friction may negate this temperature difference. Maybe it's just that contractors aren't driving around with nails in the back of open pick-up trucks in the winter as much as in the summer, when they do most of their outdoor work.
Because people drive and/or ride less in the winter.
