Differential gasket


Rear cover gasket is easy. Unbolt, drain, clean and replace gasket; fill with proper gear oil. Pinion seal on the front of the differential, different matter. If its the pinion seal leaking, take it to a shop with experienced techs.

How do you change a wheel seal on a mercury mountaneer 1998 rear end


Axle Vent
NOTE: If the vent cannot be cleared, it must be installed new.
A plugged vent will cause excessive seal lip wear due to internal pressure buildup. If a leak occurs, check the vent. Make sure the vent hose is not kinked. Remove the hose from the vent nipple and clear the hose of any foreign material. While the hose is removed, pass a length of mechanics wire or a small diameter Allen wrench in and out of the vent to clean it. Connect the hose when done. The vent is located on the drivers side top of axle housing.
If you plan on doing most repairs yourself I would suggest buying a Haynes or Chilton manual for your particular vehicle. Or there are some data disks on e.bay($12-$15) For a cost of under $25, you can almost do any repair yourself with these manuals.Also there are online manuals like the site called ALLDATA where guides can be viewed for a fee. All these solutions will save you time and money, and give peace of mind over correct repairs. I can post you some procedures here also.

                                                            PINION FLANGE & OIL SEAL

                                                            CAUTION: Following procedure must be used to retain proper pinion bearing preload. Failure to follow procedure may result in premature axle assembly or component failure. Ensure pinion bearing preload is checked before disassembly, as previous pinion bearing preload will be used during reassembly.

                                                            Removal

                                                            1. Raise and support vehicle. Scribe reference mark on drive shaft-to-pinion flange on differential for reassembly reference. Remove bolts and "U" joint straps at pinion flange on differential.
                                                            Disconnect drive shaft from differential.
                                                            2. Remove rear wheels and brake drums to prevent any drag that may affect pinion bearing preload reading. Using INCH-lb. torque wrench, measure amount of force required to rotate pinion. This is pinion bearing preload. Record pinion bearing preload for reassembly reference.
                                                            3. Using Holder (6719), hold pinion flange. Remove pinion nut and washer. Scribe reference mark on pinion flange-to-pinion for reassembly reference. Using appropriate puller, remove pinion flange from pinion. Remove oil seal from axle housing.

                                                            Installation

                                                            1. Ensure oil seal surface in axle housing is clean. Coat lip of oil seal with gear lube. Install oil seal using appropriate seal installer. Drive oil seal into axle housing until oil seal installer contacts axle housing.
                                                            2. Install pinion flange on pinion with reference mark aligned. Using appropriate pinion flange installer, install pinion flange on pinion.

                                                            CAUTION: Washer must be installed on pinion with convex side of washer facing outward (away from pinion).

                                                            3. Install washer on pinion with convex side of washer facing outward (away from pinion). Install NEW pinion nut. Tighten pinion nut to 210 ft. lbs. (285 N.m). Rotate pinion several times to seat pinion bearings.

                                                            CAUTION: DO NOT overtighten or loosen then retighten pinion nut when adjusting pinion bearing preload. If pinion nut is overtightened, collapsible spacer on pinion must be replaced.

                                                            4. Rotate pinion using INCH-lb. torque wrench. Rotating torque should be equal to reading recorded in removal step 2) , plus 5 INCH lbs. (.056 N.m). If rotating torque is low, tighten pinion nut in small increments until proper rotating torque is obtained.
                                                            5. To install remaining components, reverse removal procedure using NEW "U" joint straps and bolts. Ensure all reference marks are aligned. Tighten bolts to specification. Check lubricant level and add if necessary.

                                                            Trying to find out how much oil the Triton V-10 takes when I do my oil change? I cant seem to find it or anyone who knows


                                                            It should be listed in the owners manual, but because of different oil cooler setups you may have to do the change yourself and add oil until the correct level is established..... for the first oil change.
                                                            Most likely 7 liters,but start with 5,run the engine to fill the oil filter,let it sit for 5 mins and recheck and fill to full.
                                                            Note the amount needed for next time.

                                                            Rear axle leaking


                                                            Block the front tires. Break the rear lugs loose. Jack up the rear of the truck at the center if possible. remove the wheels & brake drums. Remove the brake shoes,return springs & all the other hardware. Remove the differential cover & drain oil. If you have a posi the next step sucks. You need to remove the threaded pin from the housing & remove the axle retaining clips. All the while,being carefull of the spring in the posi unit. If no posi,then same procedure,minus the "pucker factor". After the axle is out,take a large flat blade screw driver or pry bar & pop the seal out. Keep in mind the axle bearing is probably gone too , so that's another procedure. Keep it apart,you'll be glad you did.

                                                            Rear Differential Seal Leak


                                                            No. This is a cheap repair even if you take to Chrysler or any repair facility. All they do is drop the drive line and remove the pinion nut and remove the seal and tap the new one into place. Should only take them about an hour at most to do this.
