Question about 2001 Dodge Ram 1500 Truck 2WD
The only way you can get an accurate preload reading is with an in/lb torque wrench on the pinion nut with the carrier removed.
Not knowing which differential is in the truck, I'm guessing a 9.25" rear loader type.
The correct way to do it is remove the axles and ring gear carrier. Set your preload with a NEW crush sleeve and in/lb torque wrench. Re-install the ring gear carrier and check contact pattern and backlash.
That said, you probably will be alright if you re-torque the pinion nut to spec plus a hair. Look it up in a manual. EXAMPLE: if it's 210 MINIMUM ft/lb add 5-10 lbs. Preload is 10-20 in/lbs. I have seen shops do this to save the customer money (or charge them for complete disassembly and not do the work). It should take up the slack from the crush sleeve.
This is NOT the correct way, but if you are in a bind it might work. I can't guarantee the bearing won't fail in the future.

SOURCE: rear axle noise. pinion bearing?
possibly bearings. but i wouldnt drive it till you check it out cause if its just the bearings you could possibly save the ring and pinion. it could be the ring and pinion and if it is you will need to either replace or rebuild the rear end.

There is no torque specs,this nut has to be tightened back like it was ,the best thing to do,was,to late now,is to use a torque wrench to remove the nut,and remember the torque,and when replacing it,torque it back to that spec,the reason being,there is a crush sleeve between the front pion bearing ,and the rear pinion bearing,and it has to be crushed to a certain amount,to aquire deepness into the ring gear,anyway just give it about 25 lbs torque,any more the crush sleeve will crush even more and the deepness of the pinion will be too much.
