I have a Dana 60 (might be a Dana 70) full floater rear. It has a *single* locknut, with a plastic-type inner. A small wedge is hammered thru the key-hole (into the plastic-inner of the locknut), to keep the locknut from coming out.
What is the proper procedure to torque the locknut, before I secure it with the wedge?
The manuals state:
- seat the bearing (while turning the hub), by using 50 ft-lb torque wrench on the adjusting nut
- back off the adjusting-nut, so the retaining ring engages the next notch. Install the lock-nut
This is for systems which use the adjusting-nut/retaining-ring/lock-nut
------
What I did was to torque the locknut to 50ft-lb, then back it out a bit. Like, an amount roughly of one "notch".
History:
A few yrs ago, I tightened the locknut to 50 ft-lb (right-rear)..without back it out. After driving around for a day like this, I went back & backed it out. Shortly thereafter, I began to hear squeaking noises like it came from the right-rear. It went away, but then it came back recently.
I opened it up yesterday, & the outer-bearing was fully immersed in gear-oil. It looked OK. I replaced it (I left the old race in), & installed it like above.
But, when I drove it..the dang squeaking noise is still there.
Do I still have the locknut torqued too high? A shop said they adjust the nuts by "feel".
I just realized something..there is no thrust washer between the lock-nut & the outer-bearing. ??
