How much for a shitty tailgate would some jackass Tundra owner be willing to pay to replace another shitty tailgate?

 

You tell me...

 

 

Wanna start up an after market company making replacement tailgates? By the time they redesign the truck we can retire and laugh our way to the bank.

 

Standard replacement ones and real tailgates...whoda thunk it?

No windsheild should crack from temp extremes. That is why they are tempered.

 

If the winsheild is cracking in cold temps it is cause either the glass was not tempered properly or the structure of the vehicle is not remaining stable at cold temps and is contracting to much and stressing the windsheild.

Actually, unless they have changed things recently, the windshield is laminated glass - that is why it cracks. Side glass and rear glass is tempered.

 

Tempered glass is glass that is cut/fabricated to finish spec and then run through an oven where it is exposed to temperatures up to 1600 deg and back to ambient temperature rather quickly ( a couple of minutes) using an air quench. That changes the molecular structure of just the outer portion of the glass (both sides) that makes it many times more resistant to breakage. That is why it is rather difficult to break with even a blow to the flat side. However, all one needs to do is tap the edge with a somewhat hard object, and the entire piece of glass will shatter. Once tempered, it cannot be altered in any manner.

 

Laminated glass is two pieces of glass laminated together with a PVB ( plastic type sheet) in between and then goes through a roller press and heated to bond the three (or more) together. When it receives a shock or sufficient stress blow enough to break or crack on of the lites of glass, then it will cause cracking (often referred to as spider webbing). Small chips or cracks can oftentimes be repaired so that you don't even know it was there -- if taken care of right away. IIRC Ford was the first to use laminated glass in its windshields about 70 years ago.

 

Laminated glass is also used as bullet-resistant glass (multiples layers of glass and often a layer of polycarbonate/Lexan) and sound proof rooms/applications (again depending on level desired - multiple layers - even a windshield with just 2 glass lites and PVB will deaden sound) and also it greatly reduces UV ray penetration.

 

Back in the mid nineties Toyota had a very big problem with cracked windshields. A very high percentage of them were cracked when they were unloaded from the ships at ports. Auto glass companies that landed the replacement contracts were kept very busy. The problem was due to lousy metal work that the windshield was installed on to - which by the way, installers reported a significant number already had oxidation forming as the factory paint did not properly cover the area.

 

Laminated glass does not like twisting and/or unequal stress at its glazing (installation) points. Hence cracking. Ongoing problems signal bad design and/or fabrication or glazing technique.
