left/right hand thread
Actually going to attempt to remove a wheel soon. Pretty sure my 1999 chassis with stud centric wheels has left hand thread on one side and right hand (correct?) thread on the other. Can somebody enlighten me as to which is which?

Left side is left hand thread and will have an “L” stamped in the end you can see of the stud. That is, turn the nut clockwise to remove it.
Right side is opposite and the traditional rotation.

The right side is always right hand thread. As for left side look at top of a stud on that side. If the threads and the face of the nut form a narrow V pointing to the front of the bus, they are left hand thread.
As for what side of the bus is left and right, just remember which side your wife sits on (if not driving). That is the right side because she is always right.

If you don’t have a 1″ impact and a big (1/2″ or bigger) air hose and high flow regulator on your compressor and you have to break the nuts loose by hand, they can be a challenge if some yahoo kid over tightened them during the last service. I about busted a gut getting all mine loose last year. A few wouldn’t be so bad but there are 80! of them to get all the wheels off.
Of course AFTER finishing the job I went about getting a larger air hose and better regulator. As a back up and for emergency use on the road, I made up a 6 1/2 foot long 1″ breaker bar using the male end of a 1″ drive universal joint, some miscellaneous pieces of steel lying around, some welding time, and a bit of work on the lathe and milling machine. It sure would have been handy when I was breaking the nuts loose.

What’s the wheel nut torque spec on the stud piloted drive wheel nuts?
-
About 450 going by memory.

Great work David.

I bough a 12 to 1 wrench now I can set on coaster to hold wrench let wife loosen the lug nuts then use reg half in impact

Just to add a little more confidence, my memory is five years younger than Jon’s, and it is also 450 ft lbs.

FYI over torqued nuts = cracked wheel. Now that I’m 1600 miles from home, just discovered a crack between two stud holes on R steer. Will buy a new one when we get home in April. No more Alcoa wheels in this spec, has to be Accuride.
