Need to know torque setting or adjustment of companion flange nut on transfercase of 2002 jaguar x type all wheel drive

Very similar to replacing the seal on the rear differential, although the factory service manual recommends using a special tool to pull the companion flange (that the propeller shaft bolts to) from the pinion after removing the retaining nut. Also, the FSM states you must apply a preload to the pinion using a crush washer when you reinstall the companion flange/pinion nut. This will affect the proper engagement of the pinion and ring gear.

What is the question here??

the purpose of the collapsible spacer is to get the correct pinion bearing pre load. First step is to know the required pinion preload setting for your diff. Assuming that you have the correct mesh for the gears then insert the pinion seal. Assemble the pinion flange and do up the nut while moving back and forth the pinion flange to allow the bearing rollers to seat properly. using a suitable torque measuring procedure adjust the pinion nut until that torque setting is reached. ( suitable is the correct tool or attach a round disc of known dia to the flange and by calculation of radius times force ---from say a spring balance with a string wrapped around the disc--) That is to say 12 lb pull on a 4" radius disc will ==48ft/lb torque. All diffs using a collapsible space are assembled typically..; My reference is ford

to remove front axle.to loosen front axle nut leave vechicle weight on wheel then just loosen front axle nut because axle nut torque at 217 ft lbs torquehard to loose axle nut with vechicle weight off wheel.okay. you need a 1/2 breaker bar and axle socket to loosen axle nut dont use 12 points sockets need go auto parts store buy right socket for axle nut.okay when you loosen front axle nut you need safely raise support vechicle. need to remove wheels remove fender apron seal remove transaxle fluid remove transfercase oil if you have 4WD.remove hub nut remove stabilizer bar link remove speed sensor remove tie rod end remove lower arm from the ball joint then slide the halfshaft from the hub then carefully pry the shaft from the transaxle.then install new front axle push in make sure front axle snap ring on front axle snap in place inside transmission just pull a little on front axle make its in place. when all done tighten front axle much as you can then when done putting every thing back in place.lower vechicle need torque front axle nut to 217 ft lbs.

To replace the spindle lock nut:

• Raise the vehicle and support it on jackstands.
• Remove the wheel and the wheel cover.
• Remove the spindle dust cap.
• Pull the cotter pin.
• Unscrew the spindle lock nut. If the nut is a multiple-piece type, make sure you remove all of the pieces.
• Reverse these procedures to complete the installation.
• Torque or adjust the nut according to the manufacturer's specifications

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.

I believe the size is the measurement from any of the flat sides of the lug nut across to a flat side directly across from it. So to make it easy to measure, just remove one, and I assume it would be measured as metric. An easier way would be what size metric socket fits the lug nuts? That would be the nut size.
