Hey everyone. I assume you're reading this because you have back glass rattle? Well never fear the answer is here. I have FINALLY found a solution to stop rattling the sliding back glass especially for systems that don't bang and vibrate TOO God awful hard, this works great on my one 10 in my single cab.
Ok first off you need about 1/4" wide weather stripping tape. (Can be purchased at Lowes Hardware for about 3 dollars for 17 feet roll).
Looks like this:
Then you take some of it, and you simple put it in between where the sliding back glass meets the whole back window. It should look like this: (I put about 3 or 4 on each side, you might need more or less, whichever suites you.)
Then you take some more, open the sliding back glass, and put some strips on the side with the groove that the other side slides into and locks, then close it.
There ya go, rattle free. Try it, and tell me if it works.
