Had Sam's put tires on my truck one time which will be the last time. I had a Proto torque wrench set for the factory torque in the drivers seat with a note to use this and not an impact wrench.When you sign the paperwork at Sam's it says you will re-torque after 50 miles.
CYA move. But I have seen them using a torque wrench not just an impact.
There was a window to the shop and saw the guy use an impact on the aluminum wheels.
Contacted the store manager and pointed out the issue and the owners manual saying to NOT use an impact when torquing the lug nuts.
He had the tire guy back off the nuts and use my wrench to put them back on. He was visibly pissed so I stopped in the parking lot and checked the torque.
Found the guy had backed off the wrench which was calibrated by the company I worked for to about 40 lbs. He neglected to put the wrench back to the setting it had been preset for.
Went back into the store and called for the store manager again.
He saw the issue and said he would take care of it, but I don't know the final result and I torqued them down to factory specs and went down the road, checking them again when getting home.
