Installing rear manual transmision seal

installing rear brakes with rotors calipers and emergency brake shoes...

The seal where the driveshaft enters is fairly easy.
You remove the input yoke and use a seal puller, then drive the new seal in.

For the rear seal, remove the drive shaft, and the seal should be very visible there. Very fortunate, as this is the easiest and cheapest seal there is to replace! Be extremely careful installing the new one, if using a hammer or similar installation item. If it isn't seated properly the leak will continue. Good luck.

I'm not sure if this is the right part of your car but, are you talking about the rear seal on the engine for the crankshaft?

If so:

If the crankshaft rear oil seal replacement is the only operation being performed, it can be done in the vehicle as detailed in the following procedure. If the oil seal is being replaced in conjunction with a rear main bearing replacement, the engine must be removed from the vehicle and installed on a work stand.

1. Remove the starter.
2. Remove the transmission from the vehicle, following the procedures in Section 7.
3. On a manual shift transmission, remove the pressure plate and cover assembly and the clutch disc following the procedure in Section 7.
4. Remove the flywheel attaching bolts and remove the flywheel and engine rear cover plate.
5. Use an awl to punch two holes in the crankshaft rear oil seal. Punch the holes on opposite sides of the crankshaft and just above the bearing cap to cylinder block split line. Install a sheet metal screw in each hole. Use two large screwdrivers or small pry bars and pry against both screws at the same time to remove the crankshaft rear oil seal. It may be necessary to place small blocks of wood against the cylinder block to provide a fulcrum point for the pry bars. Use caution throughout this procedure to avoid scratching or otherwise damaging the crankshaft oil seal surface. To install:
   
6. Clean the oil seal recess in the cylinder block and main bearing cap.
7. Clean, inspect and polish the rear oil seal rubbing surface on the crankshaft. Coat a new oil seal and the crankshaft with a light film of engine oil. Start the seal in the recess with the seal lip facing forward and install it with a seal driver. Keep the tool, T82L-6701-A (4-cyl. engines) or T72C-6165 (6-cyl. engine) straight with the centerline of the crankshaft and install the seal until the tool contacts the cylinder block surface. Remove the tool and inspect the seal to be sure it was not damaged during installation.
8. Install the engine rear cover plate. Position the flywheel on the crankshaft flange. Coat the threads of the flywheel attaching bolts with oil-resistant sealer and install the bolts. Tighten the bolts in sequence across from each other to the specifications listed in the torque chart in this section.
9. On a manual shift transmission, install the clutch disc and the pressure plate assembly following the procedure in Section 7.
10. Install the transmission, following the procedure in Section 7.

did you seat the torque converter IN THE TRANS before installing the tranny? If not you broke the pump in the tranny. Also DO NOT tip a used tranny upsidedown it sends all the clutch and band debres into valve body. I hope this helps CJ

Do not have a diagram but there is alot of work changing rear axle seals
or seals to the 3rd member. Please buy a manual that show all the procedures for the job. It' makes the whole repair easier. I've been there - Good luck

Is it only when driving ? it may be your differential gasket that may be leaking if not than check your rear main seal those tend to go after some miles and heavy pulling

There is a manual, It's on CD. I believe the Dodge Caliper has the same brakes. If you can' get the drum off you have loosen a screw in the rear with a screw driver. My family has been changing brakes for years. You don't have to have degree to do this. lol Here's a link to the diagram for a 2008 Avenger.

In order to replace the rear main seal u have to pull the transmission out to access it, u will need a special seal installer tool to install the new rear main "full circle seal", it u don't use the special ford tool the seal will leak again, also if there is a groove worn ion the crankshaft the crank must be repaired or replaced or the or the seal will leak again, so this is avery diff job, a 9 on the scale of 1-10 with 10 being the mos difficult.
