Is it possible to convert inch pounds to foot pounds if all ya have is a clicker torque wrench to tighten the pinion nut and carrier bolts in a 91 GMC Vandura 2500 Van after replacing the bearings and races only, using the old gears and what are they.

There is a torque spec for the cylinder head; I don't know of one for the cover.

ctionsThings You'll Need

• Flywheel holding tool
• New alternator
• Socket wrench set
• Torque wrench

1. • 1Determine which alternator your Ford Taurus will need. You'll want to be sure the new alternator is compatible with your Taurus's engine. Models made from 1986 to 1991 have a 2.5 L HSC, 3.0 L Vulcan or 3.8 L engine. The 2.5 L engine was dropped for 1992 to 1995 models, and post-1995 models will have a 3.0 L engine.
     
   • 2Disconnect the negative battery cable with a socket wrench. Release the tension on the accessory drive belt so that you can remove the drive belt from the pulley.
     
   • 3Take off the mounting bolt on the right side of the alternator with a socket wrench and remove the bracket for the power steering hose. Remove the mounting bolts on top of the alternator, the front passenger wheel and tire assembly and the front fender splash shield. Remove the alternator splash shield with a socket wrench and take off the inspection cover for the torque converter.
     
   • 4Mount a tool to hold the flywheel so you can remove the crankshaft pulley bolt and crankshaft pulley. Lower the alternator so you can unplug its electrical connections. Disconnect the crankshaft position sensor and Oxygen sensor connector. Remove the lower alternator mounting bolt and B+ connector nut to remove the alternator.
     
   • 5Install the new alternator assembly by reversing the above procedure. Use a torque wrench to tighten the B+ connector nut to 71 in. lbs. and the lower alternator bolt to 18 foot pounds. Torque the crankshaft pulley bolt to 74. foot pounds, the upper alternator bolts to 18 foot pounds and the nut for the power steering hose bracket to 13 foot pounds.

Disassembly Make sure that you have all the parts and tools you will need. The extent of disassembly depends on the job being done and the inspection findings. Lift the vehicle using an appropriate lift or a jack and safe jack stands. Always make certain that the vehicle is safely supported before working underneath. Unbolt the driveshaft from the yoke. Remove the differential cover or unbolt the third member. Let the oil drain into a suitable container. Please recycle your waste oil. Remove c-clip axles by removing the differential cross pin bolt and cross pin shaft, pushing the axles in and pulling the c-clips. Full float axles are unbolted at the hubs. Punch both carrier caps with identification marks so that you will be able to re-install them on the same side and in the same direction. Most carriers can be pried out of the housing with a pry bar. Further disassembly depends on the job being done. If you're changing the ring and pinion or the pinion bearings, remove the pinion nut with an air gun while holding the yoke, or use a long breaker bar and brace the yoke (bolt it to a long board) so that it can't move. Knock the pinion gear out to the rear with a brass punch, taking care not to damage the threads. Keep track of the location and thickness of all of the original shims. Pinion bearings must be pressed off. Carrier bearings can be pulled using a bearing puller. Internal parts (inside the carrier) can be removed as necessary.

Inspection

Inspect all bearings and races for pitting or uneven wear. The inner carrier bearing races should not spin on the carrier journals. The carrier races should have a snug fit in the housing. Inspect the carrier race bores for grooves from spinning races. The side gear bores inside the carrier should not have any abnormal wear. All gear teeth (including the spider gears) should be smooth but not excessively shiny. Inspect all gear teeth for pitting, chips, breaks, and for signs of uneven wear and overheating. Inspect positraction clutches for scoring and wear. Inspect the axles for pitted, grooved, or dull and rough bearing surfaces. Check for worn axle splines. All questionable parts should be replace
Assembly

Differential Adjustments
The four essential differential adjustments are pinion depth, pinion bearing preload, backlash and carrier bearing preload. The tables at the back can be used to write down shim combinations and results.

Preparing Parts

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.

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.

this is for 2003 7.5 inch ring gear axle.

1. Raise and support the vehicle.

1. Remove the rear wheel and tire assemblies.

1. CAUTION: Remove the rear brake calipers to prevent drag during the drive pinion bearing preload adjustment. CAUTION: Do not allow the calipers to hang from the brake hoses. Remove the rear brake caliper and support bracket from the knuckle as an assembly. Wire the caliper and support bracket assembly out of the way.
2. CAUTION: Index-mark the driveshaft flange and pinion flange (4851) to maintain initial balance during installation. CAUTION: The driveshaft centering socket yoke fits tightly on the pinion flange pilot. Never hammer on the driveshaft or any of its components to disconnect the yoke from the flange. Pry only in the area shown, with a suitable tool, to disconnect the yoke from the flange. Disconnect and position the driveshaft out of the way.

1. Install an Nm (inch/pound) torque wrench on the nut and record the torque necessary to maintain rotation of the drive pinion gear through several revolutions.

1. CAUTION: After removing the nut, discard it. Use a new nut for installation. Use the special tool to hold the pinion flange while removing the nut.

1. Index-mark the pinion flange and drive pinion gear stem to maintain initial balance during installation.

1. Using the special tool, remove the pinion flange.

Installation

1. Inspect the pinion flange seal journal for rust, nicks, and scratches prior to installing the flange. Polish the seal journal with fine crocus cloth, if necessary.

1. Lubricate the pinion flange splines.
   • Use SAE 80W-90 Premium Rear Axle Lubricant XY-80W90-QL or equivalent meeting Ford specification WSP-M2C197-A.

1. NOTE: Disregard the index marks if installing a new pinion flange. Position the pinion flange.

1. Using the special tools, install the pinion flange.

1. CAUTION: Do not under any circumstance loosen the nut to reduce preload. If it is necessary to reduce preload, install a new collapsible spacer (4662) and nut. CAUTION: Remove the special tool while taking preload readings with the Nm (inch/pound) torque wrench. Tighten the nut to set the preload.
   • Rotate the drive pinion occasionally to make sure the differential pinion bearings (4630) (4621) seat correctly. Take frequent differential pinion bearing torque preload readings by rotating the drive pinion with a Nm (inch/pound) torque wrench.
   • If the preload recorded prior to disassembly is lower than the specification for used bearings, then tighten the nut to specification. If the preload recorded prior to disassembly is higher than the specification for used bearings, then tighten the nut to the original reading as recorded.
   • Refer to the torque specification for used differential pinion bearings in the Specifications portion of this section.

1. CAUTION: Align the index marks. CAUTION: Install the driveshaft with new bolts. If new bolts are not available, apply Threadlock and Sealer EOAZ-19554-AA or equivalent meeting Ford specification WSK-M2G351-A5 to the threads of the original bolts. CAUTION: The driveshaft centering socket yoke fits tightly on the pinion flange pilot. To make sure that the yoke seats squarely on the flange, tighten the bolts evenly in a cross pattern as shown. Connect the driveshaft. .
