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.

SOURCE: Replaced rear axle pinion bearing and seal, need

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.

Hi We need the torque settings for a rear differential pinion nut and carrier bearings on a Isuzu 2,8 diesel frotier 2006 model


get the workshop manual or go see a diff repair shop
depending on the make of diff
some pinions are measured by a preload as the bearing spacer collapses to a set distance to give that preload
others have a solid spacer to get the setting
with the side bearings it is a preload measured at the crown wheel
everything is explained in the workshop manual

Min./max backlash required on diff for Isuzu KB280DT 1998model after reconditioning & prior to "running in"


around .005" -.010" measured at the crown wheel tooth
if you have back lash at the pinion yoke , that is not the backlash you need to measure as it is a combination of axle spline and side gear clearance in the diff
what is most important is the mesh position of the crown wheel and pinion teeth, preload on the pinion bearings and diff carrier bearings
you will need a workshop manual to get the correct mesh setting and preload readings

Just put a new rear diff in my 2014 Walker Evans. New diff running hot,120 degrees F at 30mph or more. Any ideas?


differentials run hot normally and I don't consider 120 F excessive
the oil in use should be 80-90 epw oil or if it is a limited slip diff, special limited slip oil of the same grade and only filled to the bottom of the fill plug hole
120 F is only 49 C
you have 3 sources of heat generation
1-- the preload on the pinion bearings
2-- the preload on the diff carrier bearings
3 --- the friction generated by the pinion / crown wheel teeth sliding past each other
the use of ep oil ( extreme pressure ) tends to keep the oil between the teeth and so reduces that friction

My Honda 2004 CR-V develops a howling noise from the rear of the car after about 20 miles of driving. I have changed the rear differential fluid, and burnished the differential clutches per Honda Service...


A howling noise from a diff is an indication of the gear mesh( pinion to crown wheel) is not correct. Several reasons being worn pinion bearings--loss of preload on the pinion bearings --- crown wheel carrier bearings failing ---not sufficient preload on the bearings---wear on the teeth from incorrect diff oil in use. or simply wrong diff oil. The grade should be 80w90 OEP for normal or special oil for limited slip diffs.

Yes what is the torque spec for the nut on the rear diff yoke?


Hi, there is no real torque spec., as the pinion gets tightened against a crush collar, creating a preload for the pinion, as the preload is tightened to 20-25 lbin, on a rotational measurement, the nut torques itself. This measurement can only be measured with the ring gear, and center section out of the housing. This may sound confusing, but this is how a typical setup would work. If you are replacing the seal, because of a leak, you could remove the flange, replace the seal reinstall the flange, snug it up, untill it is seated, then give it a small amount of tightening. You should not over tighten this nut, as it could result in pinion bearing damage. If you use caution, you can do this without an issue, Good luck...Coop

After replacing the pinion seal on my wife's 04 f150 fx4 i topped off the fluid using the recommended synthetic 75w140 gear oil. Now on deceleration it sounds like there is a humming coming from the rear...


Did you get to correctly tighten the pinion nut to the proper ft pounds of torque level? This nut sets the preload on the pinion bearings, and if this value is not correct, things can go bad quickly.

Were you also able to replace the crush sleeve?

If not, this may also be the issue.

PINION FLANGE & OIL SEAL

CAUTION: Following procedure must be used to retain proper pinion bearing preload. Failure to follow procedure may result in premature axle assembly or component failure. Ensure pinion bearing preload is checked before disassembly, as previous pinion bearing preload will be used during reassembly.

Removal

1. Raise and support vehicle. Scribe reference mark on drive shaft-to-pinion flange on differential for reassembly reference. Remove bolts and "U" joint straps at pinion flange on differential.
Disconnect drive shaft from differential.
2. Remove rear wheels and brake drums to prevent any drag that may affect pinion bearing preload reading. Using INCH-lb. torque wrench, measure amount of force required to rotate pinion. This is pinion bearing preload. Record pinion bearing preload for reassembly reference.
3. Using Holder (6719), hold pinion flange. Remove pinion nut and washer. Scribe reference mark on pinion flange-to-pinion for reassembly reference. Using appropriate puller, remove pinion flange from pinion. Remove oil seal from axle housing.

Installation

1. Ensure oil seal surface in axle housing is clean. Coat lip of oil seal with gear lube. Install oil seal using appropriate seal installer. Drive oil seal into axle housing until oil seal installer contacts axle housing.
2. Install pinion flange on pinion with reference mark aligned. Using appropriate pinion flange installer, install pinion flange on pinion.

CAUTION: Washer must be installed on pinion with convex side of washer facing outward (away from pinion).

3. Install washer on pinion with convex side of washer facing outward (away from pinion). Install NEW pinion nut. Tighten pinion nut to 210 ft. lbs. (285 N.m). Rotate pinion several times to seat pinion bearings.

CAUTION: DO NOT overtighten or loosen then retighten pinion nut when adjusting pinion bearing preload. If pinion nut is overtightened, collapsible spacer on pinion must be replaced.

4. Rotate pinion using INCH-lb. torque wrench. Rotating torque should be equal to reading recorded in removal step 2) , plus 5 INCH lbs. (.056 N.m). If rotating torque is low, tighten pinion nut in small increments until proper rotating torque is obtained.
5. To install remaining components, reverse removal procedure using NEW "U" joint straps and bolts. Ensure all reference marks are aligned. Tighten bolts to specification. Check lubricant level and add if necessary.

Rear diff pinion seal replacement, preload torque


just yank it up tight with a bar about 50cms long,their should be collapsable spacer between the taper bearings just tighten it like a professional without overtightening it so and shearing something .handfull of grease in the diff casing to slow/stop any oil leaks top up with ep 90 and away you go,the crownwheel to pinion setting is just a little wiggle woggle ,or you could use a dial gauge but its quicker and easier ,too tight and it whines and too much play and it clunks,nice little wiggle woggle and it will work fine .trust me
