I just bought new tires yesterday for my 2006 f-150 suprecrew 4x4.
The tire store tech claimed that he could not align my truck due to worn lower ball joints. He wanted $ 400.00 to replace. I purchased Moog ball joint at the parts store and have access to their free press tool ..but from here I just don't know where to start. Any tutorials out there on this replacement job?
Any help would be great.
Thanks,

The only advice I can give you is this. If the lower ball joints are shot, the uppers can't be far behind. I'd go ahead and replace them too.
