I just read this earlier thread on the Nev-R-Lube/Centramatic combination. My Centramatics are installed, and I plan to leave them there. If a 1/16" offset will harm these bearings, what will an out-of-balance wheel do them?

Have any of these bearings failed yet due to the use of Centramatic Balancers?

That is only an 'excuse'... that 1/16" could affect? More likely the hubs were damaged prior to adding the Centramatics... as they are probably made to be 'replaced'.... Welcome to the world of "planned obsolescence"...

I'd say the simple solution is to remove the centramatics before you report a problem.

How long is the warranty on the Nev-r lube hubs? ( I'm too lazy to look it up).

Here is the factory recommended torque information for the Eddie Bauer 16" SenDel T03-66655T wheel and Michelin LT225/75R16/E LTX M/S2 tire conversion I photoed at Jackson Center.

You boys haven't nearly complicated this enough as torque wrench calibration figures in as well

Note:
That placard say Max Torque: In my opinion that does not necessarily mean the best setting. To me that means. "Go any higher and something might break." I wonder how maximum can be expressed as a range. To me that's like saying the maximum number between 1 and 10 is from 9 to 10.

I guess it means that someone's wheel may break at 126 while another may not break until 130.1

When someone writes specs that indicate they don't even understand basic mathematical terminology, that leaves me a little leary of their data.

I don't get it. If the factors that dictate torque values are the make-up and elasticity of the the lug nut and lug bolt, why would a different wheel of the same material dictate a 20 ft. lbs. increase in the torque value?

Since Lucy now has the exact same tires and wheels as the Eddie Bauer, should I increase my lug nut torque to 130 ft. lbs.?

It means to me that there is a large range of acceptable values and different sources pick different values in that range either arbitrarily or for some unknown to us reason.

That reason may be whether they are more afraid of wheels falling off or of wheels breaking.

To me, as others have stated, the secret is not to find the absolute best value. If carried to extreme that value would be different for each individual wheel on the trailer.

The secret is to find an initial value within the acceptable range. Then check it frequently. If upon checking, you find it has slipped a bit increase it while staying in the acceptable range. When it no longer slips then that and bit more is your value.

There is no magic number that will allow you to relax your vigilance.

Not really knowing what to do, I am considering splitting the difference and landing on 120 ft. lbs. This seems like it will be tight enough to prevent the wheel from falling off, but not so tight as to break anything.

In retrospect, Old Lucy had a set of 16" Michelins that were installed at Jackson Center. They never mentioned increasing torque value on the lug nuts. For the following 60,000 miles, I used 115 Ft. lbs. for the Lucy's lug nuts. At that time, Airstream was recommending 110 to 120 for lug nut torque. I never had any issue with Old Lucy's wheels.

What think you all?

as

As we are to check them prior to any departure the value isn't as critical.

Very good point.

For instance:

How many times have you dropped the torque wrench?

Did you buy from Snap-On or Harbor Freight?

The point to get out of all this is:

The only thing this subject has in common with rocket science is that the theory is not proven until its tested and checked many times in the field.

I'd like to know if the lug bolts on an Eddie Bauer are the same as the rest. I assume they are but a "look see" into that might shed a little light on the torque specs.

Brian,

I think you are sweating this too much. If you are not comfortable until you're absolutely sure it is the absolute best, you will be changing it daily. There is no absolute best value. Just pick a number in the range. If you pick one that's high, then it is more important to check the wheels for cracks around the lug nuts, if you pick one that's low then slipping nuts are the thing to watch for most.

You are to the point where you have to throw a dart at the chart on the wall and go with that value.

No matter what you do, check it frequently and adjust as necessary.

Ken
