Question about 1988 Isuzu Trooper 2 Door

1 Answer

Rear differential driveshaft seal leak.

Anyone know if you can replace the rear differential driveshaft seal without removing and dissasembling the differential carrier?
My Haynes manual only shows how to do axleshaft seals.
It appears there is a nut inside the driveshaft flange.

    Yes it is the pinion seal leaking.

    Thanks for your reply.

    I have a 1991 Trooper that needs the pinion seal replaced also. I was just wondering how your repair went? How did you go about setting the preload on the bearing? The manual says something about tightening the pinion bolt with the same amount of torque it took to get it off. That seems pretty ominous to me.

    Are you refering to the pinion seal? That would be the seal behind the yolk (driveshaft flange)?

Hello,you need to remove driveshaft to be able to get to the nut.Remove the nut (MAY BE VERY TIGHT) and pull the yoke or flange as you called it out & you can pop old seal out & new seal in.You may want to smear a tiny bit of grease or vasoline on outside of seal for easier installation & also on the rubber part of seal so itwon't get damaged when you re-install the yoke.Hope this helps.

Need to replace the seal at the differential


There are several seals for the differential. The pinion seal is towards the driveshaft. The rear cover is on the back of the differential.

The rear cover seal is a gasket and can be replaced by removing the rear cover and scraping off the old gasket. Some mechanics make their own gasket out of a liberal application of atv gasket compound. Other mechanics use a stamped gasket and may apply a small amount of cement to one side of the gasket to hold it to the cover.

The cover is bolted on by Torx head fittings.

The pinion seal is another matter. The driveshaft needs to come off. The flange needs to come away from the differential and the seal rides the shaft going into the differential. Some housings require a removal tool.

With either seal, you need to determine the type of differential you have. Limited -slip requires an additive to work in the standard lube. Some require only synthetic gear lube as well as the additive.

A cover gasket is not very hard to replace. The pinion seal can be more difficult. Price the repair.

Do not reuse the differential fluid.

I have a 2003 Dodge Ram 1500 4x4. When the truck slows to a stop, and just as it stops, there is a very loud grinding noise that comes from the rear of the vehicle. I checked underneath and there is fluid...


The fluid splattered all over is most likely coming from the pinion seal. (The seal at the front of the differential where the driveshaft yoke goes in.) Normally, you would remove the driveshaft and the pinion yoke to relace the seal. The grinding however, leads me to believe that the seal leaking is a RESULT not a CAUSE of your problem. The way you describe it sounds like you may have some serious pinion and/or ring gear damage inside the differential.
If this is the case, there are severl ways to go about repairing this. You could tear your differential apart and replace the defective/damaged parts inside. You could replace your differential with a used one from a salvage yard. You could replace your differential with a remanufactured differential assembly.

To check for damage, remove the rear cover from the differential and check for metal in the oil and in the bottom of the housing. You can also turn the ring gear around and check for broken teeth. You can also inspect the spider gears and pinion gear for damage.

How do remove the rear differential cover on a 2003 Ford Explorer? The gasket is leaking and I want to replace it. The cover is bolted to the frame member and that's alittle


The cover gasket is silicone and is not designed to be serviced without removing the differential assembly.You will need to remove axles , driveshaft , and maybe the spare tire to get differential out.

Leak at front of rear differential. How do i change the pinion seal.


Remove the driveshaft. You need an impact gun to remove the pinion yoke nut. Pull the yoke out and replace the seal. Make sure you tighten the pinion nut to the correct torque spec. (The dealer can tell you how tight it needs to be.)

How do i replace a driveshaft for a 1997 lincon cotanental


I searched under 1997 lincoln continental and found this: Driveshaft and U-Joints
REMOVAL & INSTALLATION Town Car and Mark VII-VIII Fig. 1: The bolts retaining the rear driveshaft yoke-to-differential flange require a 12mm, 12 point wrench or socket to loosen them 91197p12.jpg
Fig. 2: Remove the bolts retaining the rear driveshaft yoke-to-differential flange 91197p11.jpg
Fig. 3: Separate the driveshaft from the axle flange and . . . 91197p13.jpg
Fig. 4: . . . disengage the driveshaft from the transmission output shaft 91197p14.jpg
Fig. 5: Insert a plug onto the splines of the transmission output shaft to prevent fluid from leaking out 91197p15.jpg
  1. Raise and safely support the vehicle.
  2. Mark the position of the driveshaft yoke on the axle companion flange so they can be reassembled in the same way to maintain balance.
  3. Remove the flange bolts and disconnect the driveshaft from the axle companion flange.
  4. Allow the rear of the driveshaft to drop down slightly.
  5. Pull the driveshaft and slip yoke rearward until the yoke just clears the transmission extension housing seal. Mark the position of the slip yoke in relation to the transmission output shaft, then remove the driveshaft.
  6. Plug the transmission to prevent fluid leakage. To install:
  7. Lubricate the yoke splines with suitable grease.
  8. Remove the plug from the transmission and inspect the extension housing seal; replace if necessary.
  9. Align the slip yoke and output shaft with the marks made at removal and install the yoke into the transmission extension housing. Be careful not to bottom the slip yoke hard against the transmission seal.
  10. Rotate the axle flange, as necessary, to align the marks made during removal.
  11. Install the driveshaft yoke to the axle flange. Install the bolts and tighten to 71–95 ft. lbs. (95–130 Nm).
  12. Lower the vehicle.

put flat pan under the housing remove the bolts holding the cover usually 10 or 12 (1/2 or #12 metric) bolts? allow the rear end grease to drain... then scape off the old gasket clean with brake cleaner spray install either new gasket or form one with oil resistant silicone put the cover back on , dont refill the fliud for at least 12 hours if using silicone. Also check the front driveshaft rear end yoke seal....they sometimes leak making the illusion of a rear end pan cover leak...if that is leaking you remove the shaft carefully...remove the large yoke retaining nut, replace the press in seal...be sure retaining yoke nut is properly torqued when reinstalling .

My 2004 Mercury Mountaineer will go into gear but will not move. What could be the problem


Your rear emergency brakes could be hung up. Especially if a parking valet or someone else parked it recently.

You need to jack up both rear wheels and then put your car into neutral with the motor OFF. If the rear wheels can not be manually turned it is either the emergency brakes, the differential or the transmission.

The emergency brakes require removing the back tires and rotors. If it is still locked, then it is either the differential or the trans. The driveshaft connects the trans to the differential so remove the driveshaft. If the differential turns without the driveshaft, then the trans is locked up. If the differential does not turn the problem is inside the differential.
