How do i free up pinion bolt in a chevy rearend?


You need a 250lb torque electric impact gun to ever think about getting the pinion nut loose. It really doesn't take that much power, but the bigger the better. You also need to fix the tires so they do not turn while you getting the nut loose, otherwise the rear will just turn the tires. Only reason I figure your trying to get the pinion nut loose is that you want to change or reset the differential gears. You're best off taking it to a shop. If you don't know how to get the pinion nut loose, You're not going to understand how to do the rest of the process either. Take it to a shop or dealership Bro.

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.

What is the torque specification for the pinion nut and 1960 Chevy Impala


We are talking rear end hear correct . However torque isn't spicific to vehicles what it is spicific to is the grade of the metal V S the treard pitch V S the size of the shaft and nut .Most poinion nuts are what is called flange nuts witch means there is a base on the nut and you need 2 differant wrenches to install or remove one to hold one side and the other to break it free on tighten .The problem here is its hard to know with a torque wrench on the nut and an open end wrench on the pinion side . So take to big open ended wrenches and crank them together as tight as you can . this gives you x2 torque but the spec about 65 ftlbs to 90 lbs for most although you will not be able to measure acuralty

When changing the rear pinion seal on my 2004 dodge ram 1500 4x4 i found that the pinion nut had loosend


Sounds like you didn't tighten it FAR enough to bring the ring and pinion gears to a match point. If it's making noise on the power up side of the gears..... I'll not explain, you may not understand. Anyway, lift the rear tires off ground and pull the driveshaft loose from the rear. You'll find there's play/slop in the yoke when you turn it back and forth. Lock the tires and tighten the nut until there's practically no play whatsoever. Play must be just barely discernable to have enough backlash in the ring and pinion, and since your not pulling the rear plate/cover to check backlash with a piece of paper between the gears, this is the only way to do it. And if it's been loose for a long time, even with correct backlash, it will still make a bit of noise until the teeth reset to proper wear position.

The axle from a jeep 4x4 is broke , both axles, how do i take out the rest of the parts?


The front axel is a two piece assy. remove the 4wd
shift moter from the axel housing. Once the moter
and fork are off , remove outer axel.To remove inner
axel, remove differential cover and let it drain.
There is a C clip on the axel, remove it and work the
axel out through the axel tube.(if it is broken)
To remove the rear axel. Remove diff. cover and drain.
Remove the pinion lock nut(or spring clip) and slide
back pinion shaft. Remove retaining clip from axel
and remove axel. To remove broken piece I use to
use a length of an old whip antenna, to push it out.
If you can find a piece of heavy gauge wire to push
it out.(a plumbers snake may work)Also only have
one axel at a time out of either housing, this will
make it easier to reinstall the axels.
I hope I was of some help. Good luck.

  1. Raise and support the vehicle.
  1. Remove the rear wheel and tire assemblies.
  1. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif CAUTION: Remove the rear brake calipers to prevent drag during the drive pinion bearing preload adjustment. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif CAUTION: Index-mark the driveshaft flange and pinion flange (4851) to maintain initial balance during installation. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif CAUTION: Align the index marks. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. s3b%7eus%7een%7efile=ani_caut.gif%7egen%7eref.gif 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. .
  1. Install the rear brake calipers.
  1. Install the rear wheel and tire assemblies.
  1. Lower the vehicle.

Pinion seal leaking


check your rear diff vent if pluged clean it out and clean up the pinion seal.sometimes if the leak is caused by pluged vent and has not been leaking long once vent is clean sometimes the leak will stop.there is not a specific torque amount because it is rotational torque(how hard to turn pinion).there is a crush sleve on the pinion and if torqued too tight or too loose brg preload will be wrong and brg damage could result.mark and remove drive shaft.remove rear wheels,brakes,axles.so when turning pinion you dont have any drag from brakes or axles.mark the position of the yoke on the pinion.remove yoke,replace seal,reinstall yoke be sure to replace pinion nut.tighten nut until it takes the exact same amount of force to turn pinion as before taking original pinion nut off.hope this helps.
