So i have a 2007 nbs ext cab 2 wheel drive silverado. Went to get it aligned and they said nope you upper and lower ball joints are shot. Wierd my truck has 76k miles on it. So i took it to the chevy dealer which changes my oil every 20 days and says the ball joints are fine every time. They check them and say Yep they are bad 1300.00 and we will replace them. to pour salt in the wound they say this is normal and not un common.... my wifes dad has a classic 07 with 250k and has never touched the ball joints... Rant over

I know i have to buy the upper control arms complete can i buy those and just lower bll joints rent the tool and do it myelf on a weekend..

If so were can i get the parts online that will for sure fit
