Care must be taken not to go too fast on the tightening at this stage, so as not to exceed the 16-28 lbs-in. The drive shaft can be supported out of the way by a bar or pipe, placed on the top side of the mufflers. Inspect the mating surfaces of the rear axle U-joint flange and the rear end of the drive shaft and remove any nicks and scratches. Remove the old pinion nut, clean the pinion threads thoroughly and carefully apply premium grease to the lips of the seal. This is done by tightening the pinion nut to a minimum torque value, then attempting to turn the pinion nut and reading the amount of torque needed to turn it through several revolutions. The front tire can be removed motorcycle on lift without loosening calipers or any other parts once axle shaft has been withdrawn; after the tire has been changed and the wheel and axle shaft is back in place, torque for the axle nut is 58 ft. The torque for a solid spacer is between 13 and 33 inch-pounds.
. That's why I asked the initial question. Remove the two bolts from each bearing cap and take note of the orientation of the arrows, cast into each cap as shown in Fig. If there is a chance water has gotten in at any time it should be changed right away. Again, this is probably overkill, but it is easier to change it in my garage than on the trail in the mud.
Then add a 4ounce bottle of Ford Additive Friction Modifier. That will expose the axle nuts to the axle hub that you will need to remove to replace the inner wheel seal. If not, definately less than 25 ft-lbs makes sense. They are available from Ford, and I will get the part number if anyone needs it. The oil was quite dirty.
A spacer fits on the end of the pinion gear. The four bolts holding the drive shaft to the rear axle U-joint flange can be removed by inserting a pry bar between spaces in the U-joint to secure the drive shaft. Carefully tap the seal all around the edge with a soft punch, as not to cock or damage the metal ring, as in Fig. So I backed off to 10 ft-lbs and left it. Both axles use a third member that contains the differential, which is made up of the ring and pinion gear, spider gears and various bearings.
Squeeze the parking brake lever together and insert the end of the cable into the retaining loop, as in Fig. The sway bar must also be removed or lowered, to gain complete access to the , as shown in Fig. This will leave an imprint in the compound that will indicate where the mating teeth are contacting, as shown in Fig. Re-install the bearing caps in their proper orientation and add a couple drops of red Loctite thread locker to each bolt. The axles are retained with C-clips at the end of the axle shaft, inside the differential carrier. Have another person prepared to help ease the unit out, as it is very heavy! This will require removal of the differential case and the entire pinion assembly, removing the large pinion bearing, adjusting the shim amount, re-pressing the bearing, cleaning all of the marking compound from all teeth and re-assembling and retesting as above. The 8-inch rear axle looks very much like the popular Ford 9-inch rear axle.
It's a good idea to lubricate the drive splines in the rear wheel and the mating shaft in the final drive while the rear wheel is out. Attach the bearing caps securely and rotate the assembly by turning the U-joint flange. I changed my rear differential fluid about 3000 miles ago, and it has been leaking ever since. If the minimum torque needed to rotate the pinion nut is not established by the minimum nut torque, the nut must be tightened further, in small increments, until the proper torque value is established. This pattern is important to insure the strongest gear set possible.
Has anyone had any problems with the plastic cover? If too close to the inside diameter toe of the gear, remove shim thickness. Also, how often should you replace the fluid? If the preload exceeds the specification at minimum torque, a new spacer must be installed on the pinion gear. First item of business is to disconnect the negative cable of the battery, so as to not accidentally set off safety features such as air bags, etc. While holding it in place, install the old collapsible spacer, new bearing, oil slinger and rear axle U-joint flange from the front side. Remove both rear wheels, giving access to the two sway bar bolts on each side.
I just put mine cover back on and after about 10 ft-lbs. The 8-inch Ford rear axle was used from the early 1960s to 1980 in small and mid-size passenger cars with six- and small-block V-8 engines. Alternator replacement 2005 2006 Ford Escape 3. Slide the brake rotors on and attach the caliper support bracket with a couple drops of blue Loctite thread locker to each bolt and torque to 65-87 lbs-ft. Growing up I was either camping, at the farm, or at the racetrack.
Carefully remove the anti-lock sensing cable from its retainer and twist tie it out of the way, preferably to one of the spring coils, as shown in Fig. Click this link below for complete detailed procedure:--- -------------- This should help. However, the metal cover uses different bolts than the composite cover. The front end parts of the pinion assembly collapsible spacer, small bearing, and oil slinger can now be removed save these parts for later use. Push the axles in toward the center of the differential as far as possible, in order to expose the slot on the inner end. Do this in relatively small increments.
Then the 25-35 ft-lbs makes sense. The minimum torque is 170 foot-pounds. A certain pressure -- or preload -- on the pinion bearing and spacer must be established. Tighten in a crossing pattern to 76-89 lbs-ft. Is 100,000 reasonable if you have extended the breather tubes so no water gets in? Once the proper pattern is reached, the differential and pinion assembly are again removed, cleaned and the bearings coated with some of the new gear lube to be added later and re-assembled. When changing gears in a vehicle with high mileage 60,000 , it is suggested that the bearings also be swapped.
