Not A Body, (Caliber), Ball Joints

Found a bad ball joint on the 08 Caliber yesterday when I was swappin on my snow tires,...( I actually heard it a while ago), was told this may be covered by my lifetime bumper to bumper warrenty,(drivetrain only so's I doubt it),...

Lookin to see if there are any TSB's on this.

My Dad's Compass,(same platform), had the same prob, was told by the stealership that it was covered, however they didn't/couldn't get it done @ that time, told him to go local and they would reimberse him, just bring back the reciepts,....So he did,...went back to the stealership, and was told it was not covered cause they didn't do the work,....*** CLOWNS,...

This has been a good car, survived a reindeer hit last Xmas to the tune of $4600, was covered by insurance,...only done a battery, a set of tire's and routine maintenace, got 69 thou on it, and I'm down to a $200 dollar payment on it...(yay)...

Went to Caliber ForumZ site, been a member fer a long time,not a lot of help there...just don't post a lot there,....FABO has been a better site for me,...

Any help folks?...
