I have a 1999 Chevrolet Tahoe that needs new upper ball joints, pitmen
arm & idler arm due to ware. Our local mechanic wants $550 to do the
job but I'm thinking about taking the project on myself. I have a
full mechanic shop at my disposal (Military DIY shop on post), but am
not sure if I'm getting in over my head. Whether I do the replacement
myself or not, is there anything else I should be thinking about
replacing while under the truck?  Where can I find a good resource for
step-by-step instructions on doing the job myself? Is Chilton's worth
getting, or is there a better guide? Last but not least, should I be
taking on this job myself, or is it worth paying the $550 to have the
professionals do it? Any help would be greatly appreciated!
