Lugnut torque
« on: January 24, 2018, 03:08:55 PM »
 Having difficulty getting Lugnuts off my front tires and believe they are over torqued. Does anyone know the torque foot pounds that the front steer tires for my patriot is supposed to be? Tnanks.

I assume you have 10 hole alum wheels and the torque is 450-500 ft/lbs dry. Call a truck tire service to take your fronts off. I have a shop full of tools and don't mess with tire or wheels, been there done that.

Fred,

Just a reminder, depending on which side you are working on one side are right-hand threads and the other side is left-hand threads.

Fred,
Over torqued lugs is a common problem on coaches. Truck tire shops use 1 inch impact guns that produce well over 1,000 foot pounds and your wheels should be torqued to 500 foot pounds. Some, but not all truck tire shops have started using a torque wrench to tighten wheels because of legal issues.

I know of at least two BAC owners who have had wheels crack from over torqued lugs, and one coach that broke down one the road because of multiple broken lugs while driving. Also remember, like Karl said the right side lugs are right hand threaded and the left side lugs are left hand threaded on your coach.

 So, what you are saying is the right side lugs are turned clockwise to tighten and the left side is turned counterclockwise to tighten. Is that correct?

Fred,
That is correct, and it will be very obvious to you if you look closely at the lug bolt threads.

All my wheels are M22x1.5 right hand flange nuts on 10 hole wheels.

Lee,
I understand, but Fred has a 2002 model with lug centered wheels and Bud nuts, not hub centered wheels and flange nuts like your coach.

Fred, I bought an air impact gun rated for 350 pounds of torque when I bought my coach in 2004. I had to go to a truck tire shop to get the lug nuts loose and I then tightened them with my gun. For the past 14 years I have used my gun on my wheels and have never had a lug nut come loose. Also I am able to remove the wheels at my home.

As a retired mechanic, I carry 3 air impacts and a 1/2 drive battery operated impact gun in my coach. The largest one is a 3/4 inch drive IR composite gun that is rated at a maximum torque of 1350 foot pounds and I have still seen truck tire shop installed lug nut that it would not remove. Therefore, I also carry a 3 foot long Snap-On 3/4 inch drive ratchet and a cheater pipe for lug nut removal when needed. Those guys with the 1 inch drive guns really get carried away at times.

On our 10 hole wheels with M22 nuts we would run them with a 3/4 impact and torque with a 1" drive torque wrench set at 500 ft/lbs. When I had the front blow out in Utah and they Bridgestone replaced both front tires they also ran them with a 3/4 than with torque wrench.
My 77 Freightliner and 79 Pete had bud wheels which were a real pain, so glad when all switched to the 10 wheels.

There are many Torque Multiplier kits on the market for doing work on wheel nuts, I've seen them for as low at $70, I was actually thinking of getting one just in case, beats carring a breaker bar and sockets big enough to move a lug nut.
