Both windows making a loud sound when lowered

Hello All,

I've just purchased a Viper and I believe I have the notorious window regulator issue. I've read thru many threads trying to understand the remedy and looking for confirmation before ordering parts and throwing money at it.

ISSUE: Windows both work 80%. When rolling down, they make a loud squeak/chatter when going all the way down. I can lower them 80%, no noise. The last 20%, the noise is there, both lowering and raising.

So I believe the window regulator parts are worn. I'd like to get in there and remedy it before the regulator breaks.

I'm not sure which product would help solve my issue?

Thanks in advance!
