Hello to all....

Front Left Window lower down all the way smoothly. But yet when raising, window has this weird sound almost similar to something cracking on some point and a little binding with the felt lining? It's been a while since I did apply silicone lube to the felt lining. Never replaced the window regulators. Still original parts with now at 165+ miles. Would like to also confirm that the problem is the window regulator beginning to go south. Would replacing both front regulators the same time ok even though the right side is working fine? But for how long?
