Jacking Up Axle Required for Lug Nut Retorque?

doesnt take much to torque them on. It takes alot of hammering on a 1 incher to overtorque them to the point of stretched stud or cracked aluminum rim.. Cant recall but yeah i think 450-500 is what lugs say on them. my torque wrench goes to 550. so thats where i usually go.

 

Talking about cracked aluminum wheels, well, I discovered that one of mine is a bit cracked.

 

it happens. i had a air leak and couldnt find it. i resorted having to take wheel off and putting it in my swimming pool to find it. The air leak was becuase of a hair line crack in the rim itslef. Crazy right?

 

Good gravy, this isn't rocket science or brain surgery. Run them tight with impact while wheels off the ground and brakes released then set wheels on ground and torque. Done...

Personally I've been around trucks 20 odd years, changed hundreds of tires my self and been to countless tire shops. Never ever have I seen anyone break out a torque wrench, yet somehow I've only seen one set of wheels go flying off a truck! Only place I've seen use a torque wrench was Walmart on my pickup

 

Well that’s fine for some people. But when you are an owner operator, checking a couple of lug nuts gives you piece of mind goin down the road. No reason to get upset over the account that people check torque.

 

You forget that with diskbrakes you can warp some .

 

What kind of shops do you go to? Most shops I have gone to will have drivers witness the torque and sign the receipt as proof, and then they’re told to get a retorque some 100-200 miles down the road. The receipt will also state this.

Sure, many drivers will disregard the retorque, and it likely won’t be a problem because big fleets have so many tire problems that the lug nuts will be taken off within one year to replace a tire.

 

Yeah I'm not over the road so I don't use the big name places

 

I have experienced this and this is where it comes from.

When the wheels are removed and if the air brake chamber is allowing the wheels to turn, when the air is released and the full pressure of the shoes apply the brake drum MAY not be fully against the hub.

When the wheels are tighten by the lugs the it's not seating against the hub, when the brakes are released the drum falls slack from the axle.

This happens after brake jobs, wheel seals, adjustments.

 

I've never jacked up a wheel to torque them. Ever.

Rattle them up with my 1/2" impact and put the torque wrench to them once its on the ground. Brakes released, wheels chocked.
