Rear diff pinion seal replacement, preload torque

Hi I would like to know if there is an easy way to get the right preload after replacing the rear diff pinion seal in a 1990 Toyota Celica gt-4 st185 (4WD) as I don't have a torque wrench?

If not then what torque should the preload be at? and how do I measure it?

Thanks a lot
Andrew

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

What if no pinion bearing preload was recorded before disassembly of rear diff pinion seal


The only way you can get an accurate preload reading is with an in/lb torque wrench on the pinion nut with the carrier removed.

Not knowing which differential is in the truck, I'm guessing a 9.25" rear loader type.

The correct way to do it is remove the axles and ring gear carrier. Set your preload with a NEW crush sleeve and in/lb torque wrench. Re-install the ring gear carrier and check contact pattern and backlash.

That said, you probably will be alright if you re-torque the pinion nut to spec plus a hair. Look it up in a manual. EXAMPLE: if it's 210 MINIMUM ft/lb add 5-10 lbs. Preload is 10-20 in/lbs. I have seen shops do this to save the customer money (or charge them for complete disassembly and not do the work). It should take up the slack from the crush sleeve.

This is NOT the correct way, but if you are in a bind it might work. I can't guarantee the bearing won't fail in the future.

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.

Can some one tell me the torque spec. on rear pinion nut ?


It depends if you are replacing the pinion seal or fitting up a whole new pinion collapsible spacer. If it just the seal that you are replacing then the tension will be to do the nut up until it is firm. Any over tightening of the nut will further collapse the spacer and over preload the bearings . If you use a new spacer then the tension on the nut is determined by a turning torque on the pinion flange as measured by a spring balance and string. To get it right consult a workshop manual.

Rear differential seal


There are two places it can leak from. The rear differential cover or the pinion seal at the front of the differential. Both are easy to replace. The pinion seal will require a little more labor than the differential cover plate. You will have to remove the drive line and then break the pinion nut loose. Use a good impact wrench for this and a six point socket for that step. Then you will need to remove the yoke from the pinion gear. Should be able to tap it off. If not use a puller. Remove the old pinion seal with a flat tip screw driver by driving it through the lip of the old seal and push the screwdriver to the side and it will pop out. Clean the hole for the new seal. install the new seal and the yoke. Tighten the pinion nut. You will need to get access to a manual to check the bearing preload on the pinion nut. Then use a torque wrench to check for correct bearing preload. Re-install the drive line.

My rear diff housing is leaking quite badly. is it possible the pinion seal is the problem


yes it is very possible. to confirm where your leak is, look in 4 places. 1) rear diff cover..... 2)pinion seal, where your driveshaft goes into the rear end, or axle seals, just look and see if there is any fluid on the inside of your tires.

1984 Toyota pickup leaking fluid where the drive line connects to the differential. Bought the rear seal. What is involved in replacing it.


tearing the rear-end apart, replacing that seal, you might as well have new bearings put in as well!
Also this is a more "advanced" repair, having to use plastigauge(or equivalent) to get your clearences EXACT!!!
Good luck

I need to know about how much it will cost to replace the rear diff input seal on my 2002 f 250 4X4


Your talking about the pinion seal right? If so then it should take a reputable shop about 2-4 hours to complete. they have to take a "preload" measurement before and it has to match after the new seal is installed. Total cost is dependant on the labor rate in your area. Figure about $80.00/hr average so with parts I would figure about $200.00- $350.00

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
