    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

    I think I'd get a third opinion. Have you been greasing the balljionts. 76K does seem to be premature wear. I have almost 89,000 on my LIFTED '05 with oversize tires and still have factory balljoints.

    If you have any mech. skills you can change them yourself and save alot of money. $1300.00 is way to much money to replace all the balljionts.

    What if any is the recommended interval to lube factory balljoints?

    On my 07 the uppers are non servicable parts no grease inserts. But yeah i am just gonna change them my self this weekend. Bought them from a local autoparts store Lifetime warranty which beats the dealerships limited one year.

    so any ideas on how to press out the lower ball joint... i am assuming it presses out toward the ground.. but on top it ppears the factory flared the top of the ball joint or there is somekind of covr on it. i am at a loss here

    no not yet i had to overnight the correct ball joints from RA monday they will be here toady after tons of research it appears the NBS LT have aluminum lower control arms. Once u get the tire off and take the Brake line loose from the upper Control arm. You can then take out the 2 bolts holding the calliper on and let it rest on the lower control arm. I did have to use a Fork to lossen the lower Ball joint from the spindle. The upper i was able to just smack with a hammer to free it from the spindle. then u just let the hub asesm rest on the ground tie rod still attached. Used a file to cut back the factory ball joint as the flare 3 sides of them on the top and it will destroy the arm if you press it out and do not remove them before pressing it out. I got the lower start with the Ball joint press then just smacked it a couple times with a hammer and it came right out.

    Of course my truck is on a jack stands with a jack under the control arm taking up the spring pressure
