I do this for a living...and I DO NOT recommed that anyone attempt replacing their own windshield, rear quarters or back glass on most late model vehicles...Why? Simply because there is more there than just keeping the wind out of your hair and the bugs outta your teeth. Anymore the Windshield is used as a structural part and is designed to save your life in the event of a roll over...if it's improperly installed, that windshield could release causing you and anyone else in the vehicle to either be ejected or squished in the twisted wreckage as the roof crushes in...not a pretty sight
Simply put this is not a DIY job...most other jobs on your rig can easily be done for those of us that have little to no knowlege other than a manual...Most glass is not...If you don't properly clean, prep, prime and use properly matched adhesives you're asking for leaks, or worse.
It's worth taking it to someone else and let them take the responsibility and liability down the road if it's not done correctly...What's a hundred or two hundred bucks weighted against your family and their safety?
