There is no set torque for a pinion nut, it is turned until the crush sleeve behind it exerts the correct "preload" on the front Pinion bearing. The crush sleeve must be replaced when the seal is replaced.

SOURCE: what are the torque specs for the pinion nut and

Most pinion nuts don't have a published torque spec. they are to be tightened until the pinion requires a specified torque to spin with the wheels and brake drums removed. Often times, when a rebuild is not performed, it should be torqued to the same preload as before the work. autozone.com has alot of good repair info and diagrams.

What is torque spec for 1964 Riviera rear axle pinion nut?


The same book that I hope you used in setting the ring and pinion backlash will give you the ( Rolling Torque). Once the pinion nut is set, a new crush sleeve will be required to correct. This axel will not go around the block if back lash is not correct.

the answer is not simple , why not read the FSM and unstand it all.
experpted....
  1. On 1990-98 models, set bearing preload as follows:
    1. The required pinion gear bearing preload torque is 1/2 ft. lbs. over the noted release torque as measured above.
    2. Rotate the pinion gear three or four times with a torque wrench attached to the yoke nut. Measure the amount of torque necessary to rotate the pinion.
    3. Using a holding tool, tighten the yoke nut in small increments and remeasure until the specified torque is obtained.

I need the torque specs on a rear axle pinion nut for a 2003 Dodge Ram 2500 4/4 Cummins, Automatic.


The pinion nut does not have a torque spec. as in how tight the nut is. The amount of torque is measured in bearing preload. You will need a "torque to rotate" torque wrench. If you are using new bearings the torque spec. is 15-25 in. lbs. If you are using your old bearings the torque spec. is 10-20 in. lbs to rotate. To measure this you will need to tighten the nut in small increments then use the torque to rotate wrench to turn the pinion without the carrier/ ring gear installed. Repeat until desired torque is reached.

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.

Torque Specifications


1. If you are speaking of the large yoke nut there is no "torque spec" per say, instead it is a rotational preload-

From Ford manual:
Use the special tool to hold the pinion flange while tightening the nut to set the preload.
  • Tighten the nut, rotating the pinion occasionally to ensure the differential pinion bearings are seating correctly. Take frequent differential pinion bearing preload readings by rotating the pinion with a Nm (inch-pound) torque wrench. The final reading must be 0.56 Nm (5 lb-in) more than the initial reading taken during removal.
2. If you are looking for the yoke straps that hold the universal in place to the yoke it is 14ft lb for the 4 bolts.

I cant get the axle out of the front diff what is holding it in 2001 dodge durango


here is a diagram on how to get the front pinion seal out and it does mention how to get the axle loose. please do not forget to rate and comment about your experience with fixya today.
  1. Before servicing the vehicle, please familiarize yourself with safety procedures.
  2. Remove both half shafts.
  3. Mark propeller shaft and pinion flange for installation reference.
  4. Remove front propeller shaft.
  5. Rotate pinion gear three to four times, to verify pinion rotates smoothly.
  6. Record pinion flange rotating torque with an inch pound torque wrench for installation reference.
  7. Hold flange with Holder 6719 and four bolts and washers.
  8. Remove pinion nut.
  9. Remove flange with Remover C-452.
  10. Remove pinion seal with a pry tool.

To install:
  1. Apply a light coating of gear lubricant on the lip of pinion seal.
  2. Install seal with Installer C-3972-A and Handle C-4171.
  3. Install pinion flange onto the pinion with Installer C-3718 and holder.
  4. Hold pinion flange with Holder 6719A.
  5. Install new pinion nut and tighten nut until there is zero bearing end-play.

    CAUTION Do not exceed the minimum tightening torque when installing the companion flange at this point. Damage to the collapsible spacer or bearings may result.
  6. Tighten pinion nut to 271 Nm (200 ft. lbs.).

    CAUTION Never loosen pinion nut to decrease pinion bearing rotating torque and never exceed specified preload torque. If preload torque or rotating torque is exceeded a new collapsible spacer must be installed.
  7. Record pinion flange rotating torque, with a torque wrench. Rotating torque should be equal to the reading recorded during removal plus an additional 0.56 Nm (5 inch lbs.).
  8. If rotating torque is low, tighten pinion nut in 6.8 Nm (5 ft. lbs.) increments until rotating torque is achieved.

    CAUTION If maximum tightening torque is reached prior to reaching the required rotating torque, the collapsible spacer may have been damaged. Replace the collapsible spacer.
  9. Install propeller shaft with reference marks aligned.
  10. Install half shafts.
