RE: Conmet preset hubs
Updates on checking drive hub bearing torque.

Found one that has a different nut than the other 3 hubs. It uses the captured nut like my front hubs. The size of the nut as well as the retainer ring is different. Why one of the four is different I don't know. The axle nuts had paint in the threads. I don't know if it was factory paint or some one had painted it. I will say if the 4 drive axle hub nuts this was the only one that was tight. Put torque wrench on and clicked 500ft/lbs.

Now the other two rear axle hub nuts were hand tight. Took one off with my hand. Ridiculous. I know someone had been into one before cause they used silicone for axle flange gasket. The nuts can't back off so. Whomever is doing this doesn't know what they are doing. I have had 3 drive axle nuts loose and 1 steer loose. These are the easiest to do torque and you are done. No guessing no figuring just torque and forget.
Here is a picture of the type of lock they use.

RE: Conmet preset hubs
250+ ft-lb specification hub nuts are typically for sleeved hubs.

non-sleeved hubs, it is typically 50-70 ft-lbs.


Did you verify all the axle sleeves were present on the ones that you say were under-torqued?

RE: Conmet preset hubs
Ya, now that I looked at that picture. I have the same nut system. But I do NOT have crush sleeves. They have a totally different torque pattern then the ones with the crush sleeve. You can NOT mix the 2 up. It will be very dangerous to move the vehicle if you do. I would verify you have crush sleeves behind that nut before running it. You risk trashing the bearings and catastrophic failure if you torque the nut to crush sleeve specs. Without having them present.

RE: Conmet preset hubs
Made it 260 miles wheels haven't feel off yet. Yes I did check to verify that sleeve was in between bearings before torqued down. Wheel we off the ground and spun nice and free.

Why the nuts were not torqued down is something I can't answer. I know two of the hubs been messed with because one was done when I bought truck and another had silicone for an axle flange gasket. I don't foresee any troubles with my hubs.

Next is front spring pins and bushings. Mine has the threaded pins. Hopefully it won't be too bad.
