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

What is the rear pinion nut torque spec on a 2008 dodge nitro?


This is not set by torque value. If you had it off to replace a seal, you were supose to use a chisel to make an alignment mark and count the number of threads exposed beyond the nut, Initial setup is done before the carrier is installed, so too late for that now. If you have no other way to do this, tighten until all play is just removed and tighten another 1/8th to 1/4 turn and hope for the best. If it seems too load in operation probably too tight.

Rear end is leaking fluid where it connects to the drive shaft


you mean rear axle pinion seal. to change it you need to remove driveshaft. take a torque wrench to see the running torque. then remove center nut ,remove yoke. with screwdriver remove seal; reverse proc. then tight center nut to torque you find before you remove the center nut.

How do u replace rear pinion seal,,do u need a puller to remove the yolk?


To remove the yoke, you need to remove the nut on the end of the pinion shaft. When you do that, you MUST count the turns as it comes off, including part turns. You can do that by marking the housing and the nut and putting another marking on the socket in the exact same position. If you don't do that you will change the pinion depth of the gearset and cause it to fail. (nut needs to be put back on with the exact same number or turns)
The yoke most often comes off easily or with a light tap of a hammer. Make sure you put that back on exactly in the same position you found it as well. Don't allow the differential to turn after you take it apart and also, use a large pipe wrench to hold the yoke from turning when you put it together.
Don't forget to check the lube level when you have finished,.

Rear pinion seal replacement


You'll need to remove the yoke from the rear end, you can use a seal removal tool, to remove the seal. Make sure you properly torque the nut down that holds the yoke on.

Need to change rear seal in rear end need to know steps to remove


Raise vehicle and secure it safely. Remove drive shaft.
Remove large nut in the center of the yoke on the differential. This is tight. It is easiest to do if you have an impact wrench but can be done if you can hold the yoke enough to keep it from turning. You can help keep the yoke from turning by applying the emergency / handbrake. The nut comes off counter-clockwise.
Tap the yoke with a hammer from the rear so as to slide it off the pinion shaft. Use care not to damage the yoke or mess the threads up that hold the drive shaft U-joint in place.
Using a small slide hammer with a screw- attachment, you can either drill a small home in the seal or use the slide hammer to drive the screw into the seal enough to screw it in further. Us the slide hammer to yank the seal out. If you don't have a slide hammer or a seal remover tool, you can take a good stiff screw driver (I have one that is broken end that I use when I need it) and grind an angle on one side kind of like a chisel. Using this broken screw driver (or small chisel) drive it in the seal close to the edge enough to pry the old seal out.
Care should be taken to not score the housing or other parts that the seal may mate with, otherwise you will have a leak from now on.
Carefully drive the seal in the differential housing by tapping it evenly all the way around until it goes in flush. DON'T drive it in on one side then the other because that will destroy the new seal. It is a good idea to lubricate the new seal inside-lip with grease before installation.
Reassemble the the yoke on the pinion shaft and tighten it to the desired torque. If you don't have a torque wrench, even though it is not recommended, you can tighten it by hand or impact. Keep in mind that it has to be TIGHT! You don't want to lose it driving down the road. It is also a good idea to check the backlash of the yoke as you tighten it. There is a crush sleeve between the two bearings that if tightened too much can cause too much pre-load causing premature bearing failure. It is also recommended to replace the pinion nut with a new one every time it is removed. Reassemble the rest in reverse order of removal.

Torque specs on rear differential. And proper installation procedures on the crush sleeve


Put it together without the seal in place, you may have to take it apart again. You want to have about 8-10 inch pounds of preload on new bearings, less on used probably just a light drag. I recommend using a 3/4 in drive socket and ratchet and you have to hold the yoke somehow, a pipe wrench works but it's kind of crude. Put a little oil on the bearings and on the threads, if you have a new nut, save it for your final assembly. It's best to have helper because you really have to pull on the wrench to get the crush started. Once the sleave starts crush it gets easier, tighten the nut until the the end play is gone, check it frequently and spin it occasionaly as you tighten the nut. Once the free play is gone and the pinion still spins freely carefully continue to tighten the nut until you feel drag on the shaft. You need a dial type inch pound torque wrench to check the preload not a click type. If you don't have a torque wrench you can do it by feel it should take a little effort to turn the shaft you should be able to turn it by hand. Once you confident you have the right preload you may want to put the ring gear in and check the backlash and wear patern. If you are just replacing the bearings you shouldn't have any trouble. If you are changing the gears you could run into all kinds of problems and may need to seek a pro to help. If the gears are not set up right they will make noise and the gears won't last. Once you sure you have everthing right remove the pinion nut and yoke and put in the new seal. Clean the oil from the threads with brake parts cleaner and put some blue lock tight on the thread. Install the yoke and the new nut using care not to crush the sleave anymore but, at the same time make sure it's tight. I hope this helps, good luck.

  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.
