Faulty Frames?

[bryan4.8]

 

 

I own a 1999 GMC Sierra and i can count 6 different cracks in my frame over the last 3 years. I have off-roaded the truck pretty hard btw. But non the less this is ridiculous. I've also seen another '99 model Seirra broke right off between the cab and box. Is there lighter frames on the '99 models?

 

 

 

Where the cracks are:

 

 

 

- driver side, above the upper control arm. 6" CRACK (the frame is fully boxed here!)

 

- passenger side, under torsion key crossmember

 

- both sides, in the back around where the rubber bumb stops are on the frame.

 

- driver side, between the cab and box. completly broke the frame off here. box was pressing against the cab and ruined my paint job!

 

- also ripped the top mount for the front diff. off the frame.

 

 

 

I also noticed on '00+ models just behind the cab where the frame curves upward that there is now a brace on the inside frame-rail. Why didn't my truck have this brace? I have looked at other trucks and noticed that their frames are actually thicker.

 

 

 

Im pretty pissed off and tired of welding and boxing in parts of my frame. What do you guys think??
