Torque specs

[Rich]

What is the torque spec for the axle nut on a 2010 Lacrosse. I can find 184 ft/lbs but that seems like a lot. Any other numbers out there?

This might vary from year to year and wheel size to wheel size. On mine, it is 110 foot pounds. I had just looked that up this morning. If I have my tires rotated at a non-Buick shop, they do not instinctively use the right torque.

At one shop, I watched the technician rotate my tires and then use a torque-stick to reapply the nuts. I immediately asked him what torque setting he used, and his answer was "I don't know." That was the wrong answer, and I don't do business there anymore.

Torque Adapters are a tool used with air wrenches, where the air wrench is capable of much more torque then the specified wheel torque ratings. If they use the right adapter, it should be OK. The adapters are usually color coded, so they know the correct torque when they remove them from the box.

Yes, but "I don't know" is always the wrong answer.

Typical tire changer/mounter response! They are mostly young beginners in the automotive world, and just paid a notch above the hamburger flippers at the local MacDonald's! I hope you find better results with your question elsewhere!

Where did you read the 184?

Foot/pounds is not a legitimate quantity. Foot-pounds is normal.

On page 11-3 of the 2010 Buick LaCrosse Owners manual, the specified wheel nut torque is 110 ft lb.

OP said axle nut, not wheel nut. For the front, 184 ft lbs is correct. Actual procedure is initial torque to 111 ft pounds, then back off 45 degrees, then re-torque to 184 ft pounds. (110 for the wheel nuts is correct)

still sounds high to me for the axle nut, I wonder why the OP needs to tighten the axle nuts...

I'll bet either he changed the hub and bearing assembly or the axle/CV joint - neither is uncommon.

The axle nut is a self locking design, so the torque spec is important, but likely not critical...it just needs to be good and tight

Okay.

In my Corvette the spec is 140 lb-ft, they are notorious for getting loose and require to be replaced (and not retightened) and use Loctite.

Yeah, I know they sometimes (always?) say to replace, not re-use, the axle nut, but I have always re-installed them, no locktite, and never had a problem. I'm not saying that's what anyone else should do - just saying what I have always done.
