Wow. I used to off road pretty hard and my entire suspension / steering has been replaced more than once. They never complain when parts are good. The last time I was in there after replacing a pitman and idler arm the tech was pleased with it being in good condition. Even said he'd like to buy a truck in that kind of condition.I would just get/pay for the alignment when & if you need one.
I've been turned down on the LIFETIME ALIGNMENT from Good/Year because I installed new suspension parts and needed an alignment.
They can turn you down for just about anything after you've paid them all that money. Better read the fineprint
