I just put some 1.5" on my truck. But my front
brakes are not vented yet, so I had no way to hold the axle while torquing it. I wanted to torque it to 90 ft-lbs, but instead just gave 'em a couple hits with the ol' impact. Decided it was good, then put the wheel on and put the truck back on the ground, and then I torqued my wheels to 90 ft-lbs...
Then I had to take the tires off when I got my 33"s so I checked the spacer bolts again with the impact and everything was a-ok. Then I torqued my new tires back to 90 ft-lbs.
I am not using any loctite.
I see no problem with wheel spacers or my tires coming off. As you check everything the same day, you should be fine. I drive down the street and back, and then retorque them immediately. That's really all you need to do.
