Front Suspension Lower Ball Joint problems of the 1997 GMC Sonoma

At 85,687 miles, I had to replace all four ball joints on my 1997 GMC Sonoma 4x4. Genuine gm parts were used for the replacement. I currently have 127,532 miles on those ball joints and all four of them need replaced again!!!!. This mean that these genuine gm parts have 41,845 miles on them and are bad again!!!! after calling gm to ask for some help with a warranty on the parts, of course there is nothing they can do for me.
