In the summer the grease that is in there is getting thinner from the higher ambient temps so it could allow
the parts to rub a bit more, and the thermal expansion could make the parts fit a bit looser. Do not forget
grease is nothing more than a carrier matrix to carry oil and after a certain time the oil gets depleated and
basically have the base and not much oil especially when it gets hot and the oil gets freed from the base
to lubricate some goes to lower spots that are not contact points, when it cools it kind of sucks the oil back
in a capillary action!!
