Axle Nut loose again

[J DeMaio]

Hi guys:



Well it seems the axle nut on the drivers side front is loose again. This is about the 4th time. I'm going to lock-tite and tighten again tomorrow.



I saw someone's signature that said Spicer locknut kit but don't remember who it was. What is causing this? Could you guys tell me about this kit and if anything major is wrong with the truck.



Thanks,



John

This is how I adjust the front axle bearings on a 4X4.



Make sure you have all the parts.



Make sure no parts are damaged.



Use the proper tools (special socket #7158 and 250 lbf-ft capacity torque wrench) to adjust and lock the system.



Procedure (after bearings are lubed and installed and rotor is placed on spindle):



1) Using the special socket #7158, install and tighten the INNER NUT WITH THE PIN STICKING OUT OF IT to 50 lbf-ft while rotating the rotor. Make sure that the pin is pointing AWAY from the bearing. If you currently have no pin on the inner nut then it is either an outer nut or the pin has been broken off-get a new Inner Nut ($20. 00), do not proceed without the proper part.



2) Back off the nut just until you feel it turn freely-a regualr length socket handle is best for this.



3) Tighten the nut with the special socket by hand until snug.



4) Install the locking ring. Make sure the pin in the Inner Nut is in one of the holes in the ring. The ring must be installed a certain way as it is keyed to the spindle. If the "key" is busted get a new locking ring. You may loosen or tighten the Inner Nut just enough to allow the pin to align with one of the holes in the locking ring. If you have no locking ring that is your problem-you need this part.



5) Install Outer Nut, which has NO PIN. Torque to 200 lbf-ft-yes 200.



That will do it.



The locking ring and pin on the Inner Nut positively keeps the Inner nut from turning when cinched down by the Outer Nut.

Hey bud, the lock nut kit that I posted is for the rear to get rid of the locknut and pin. Basically, the adjustment is the same on the rear as the front, as close to "O" preload on the timken bearings. If you follow the post, there is no way it can come loose!!! Fell free to e-mail me if you need some numbers. Tim

My procedure is a little different. Put the rotor/hub assembly on put the first jamb nut on put 1/2" impact on number 2 setting and tighten then back off 1/4 turn and yes it should have "a slight amount of drag" per the book. Next install ring making sure the "tit" goes into one of the holes. Next install second jamb nut nd put impact on highest setting and rat a tat tat tat tat tat. You are done.

Dfeland, my 92 service manual calls for . 001-. 010 end play on the front wheel bearings. I try to get them to (0) preload if possible. How much "drag" does the 93 manual call for in preload. Just curious as everyone interepets things differently. Thanks, Tim
