Andy your thoughts about the shop not noticing the "missing" bolts due to not wanting to place the truck on a lift
Is possible.
Before out 2016 Alaskan trip I had the truck serviced at the Toyota dealer,one I have used from the time I bought the truck used.They did a full "oil change" service and overall check,but failed to see the torn CV boot.Which to me was very obvious.
I have trust in a shops work BUT I still do a check when I get the truck back.
Not much to do but check things out before trips I guess.
All worked out for you which is good.
