SOURCE: Rear diff pinion seal replacement, preload torque

just yank it up tight with a bar about 50cms long,their should be collapsable spacer between the taper bearings just tighten it like a professional without overtightening it so and shearing something .handfull of grease in the diff casing to slow/stop any oil leaks top up with ep 90 and away you go,the crownwheel to pinion setting is just a little wiggle woggle ,or you could use a dial gauge but its quicker and easier ,too tight and it whines and too much play and it clunks,nice little wiggle woggle and it will work fine .trust me

SOURCE: torque specs on Chevy Silverado 2500 rear diff yoke.

There isn't a torque spec since those bearing are pre-loaded. You place the unit on a good known vic and get a breaker bar and you might even have to put an extention on that and you begin to tighten unitil you fell the bearing start to load...a little extra short turn wouldn't hurt at that point.

SOURCE: Replaced rear axle pinion bearing and seal, need

There is no torque specs,this nut has to be tightened back like it was ,the best thing to do,was,to late now,is to use a torque wrench to remove the nut,and remember the torque,and when replacing it,torque it back to that spec,the reason being,there is a crush sleeve between the front pion bearing ,and the rear pinion bearing,and it has to be crushed to a certain amount,to aquire deepness into the ring gear,anyway just give it about 25 lbs torque,any more the crush sleeve will crush even more and the deepness of the pinion will be too much.

What size socket is needed to remove rear pinion nut on 1997 jeep grand Cherokee limited with a5.2 v8


the rear axle front pinion DANA 44 or AMC?
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.

What are torque specs on 1965 ford 7 and 1/4 inch rear


I have a '68 Motor's manual (goes back to'58) the only rear end specs I can find are for the pinion nut (140 ft. lbs.)
pinion preload: 17-27 in. lbs. w/integral carrier or 22-32 in.lbs. w/ removable carrier. Tightening the carrier bearings isn't so much a torque setting but more or a tightening procedure. Theses specs are done during the rebuild so I wonder if you're asking about the bearing caps or bolts that hold the diff. to the axle housing? I could not find a spec. for bolt torque. Since the bolts that hold it in (if that is what you asking about) are not a bearing adjustment, you can go with a generic torque based on bolt size. Again, I'm not sure what component, or bolts it is you are asking for torque specs on.

Rear differential problems


Thing here is that when you do change a gear in a resr diff, you need to adjust the pinion gear(this is called in mecanic's word pre-load of your pinion gear)first witch is achievable by inserting shim washers and tightennig the pinion gear bolt.

Then and only then you can adjust the backlash off your diff (witch is the distance between the pinion gear and the driven gear of your diff.).

failling to do so will either cause damage to your new driven gear or as you are aving problems here not being able to turn the diff cause the backlash doesn't have enought clearance.

Hope this will help you!!

Need to know how to set the pinion nut.


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

Rear differential leaking on ford f-350 super duty


if you have never done one its best to take to dealer because you have to remove drive shaft and then rear pinion nut and remove seal the tricky part is you have to buy new crush sleeve and thats what sets your pinon depth so that pinion rides in middle of ring gear its called setting your pinion depth if over tighten will hurt bearings and or ring gear and if under tighten will be verry noisey and cause ring and pinion failure best to let someone with special tools and knows what thier doing i use to do all chevy diff at my old dealer your use inch torque wrench to measure the drag on pinion nut and then use 1/2 inch impack to tighten the nut people freak because impack is rated at 600 ft pds but your using inch torque wrench to check drag not how tight nut is good luck

Yes what is the torque spec for the nut on the rear diff yoke?


Hi, there is no real torque spec., as the pinion gets tightened against a crush collar, creating a preload for the pinion, as the preload is tightened to 20-25 lbin, on a rotational measurement, the nut torques itself. This measurement can only be measured with the ring gear, and center section out of the housing. This may sound confusing, but this is how a typical setup would work. If you are replacing the seal, because of a leak, you could remove the flange, replace the seal reinstall the flange, snug it up, untill it is seated, then give it a small amount of tightening. You should not over tighten this nut, as it could result in pinion bearing damage. If you use caution, you can do this without an issue, Good luck...Coop

Rear diffential noise when accelerating


Unless you are experienced in diff gear setup, this is not a job for a do-it yourselfer. You need a torque wrench , dial indicators and experience to set a diff up properly...If not, you will waste your money!!! Usually cheaper and easier to swap complete units, drum to drum...then all you need is to determine exact ratio of the front unit and match it. (ring gear teeth divided by pinion tooth count= ratio )
You may not like my answer, but I'm trying to save you time and aggravation and $.!!!!
good luck

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.
