100.00 online pricing for parts or there abouts. Pretty simple fix if your mechanically inclined from what I read. Later in the fall I will fix mine. My wife hates the bounce, she said it has got worse over the years. Google it online, there are a lot of GM owners that have had the issue. I placed a large old TV from my father in laws home in the back of the truck to take to the dump. That extra wieght helped reduce the bounce considerably and confirmed the issue. All Chevy does is dump a lot of wieght in the back to confirm the problem as well. Funny that some trucks have it and others don't. Like I said earlier, I drove an 03 Dmax and it had it really bad.
