Retorquing the Lugnuts

I know T/A torques to 475 with the wrench after impacting them on. I get flats repaired on trailers all the time and watch them do it. They make you sign a little disclaimer on the receipt that you watched them do it and will re-retorque them after 50-100 miles. (I never have.)

 

It's just to cover their butts, but it's really just smoke and mirrors. Over tightening is a more common problem than under tightening. Hammer them on with a 1" impact to 600 ft. lbs., of course a torque wrench will click at 475. To do it right, the torque wrench needs to finish the tightening. The next time watch close, if the torque wrench did not move the nut and only clicks, ask him how he knows that are not over tightened.

 

Grape ape hit the nail on the head.

All these rules and regulations came about because wheels have been know to come off trucks and fly down the hwy. Sometimes even killing people.

I blame almost all of this on the tire repair shops. They got there 1" long snout air impacts,rattling on your nuts with no lube that were just laying in the sand beside your axle.
They proced to burp all your nuts on goodntight.
Grab there trusty torque wrench and of course it clicks off on every nut with out even turning.
Mean while your studs have all been stretched and the nuts are sitting at 900 ft lbs. . But hey , we torqued those nuts! !!.
Do this over and over a bunch of times and eventually those studs snap and there goes the duels down the hwy .
I get a kick out of all the stupid safety items on the market for loose wheel nuts. Florescent pointers go over your nuts so you can do a quick visual to see if any have moved. Lmao!!
9 times out of 10 it's not that they come loose, it's because they were to dam tight to begin with.
This is why I do all my own tire work.
Actually this is why I do all my own work period.

 

Never thought of that. I've seen it happen both ways. Sometimes the wrench will click without budging the nuts and sometimes they will turn a tiny bit before clicking. They did lube the threads first I noticed last time. These are just fleece trailers with steelies so I've never been *that* concerned. I'm usually happy with service I get at TA shops, for basic repairs anyway.
