2004 Ford E-150 Axle Shaft Parts Q&A

• Q: How to service and repair the 9.75-inch ring gear axle shaft assembly on 2004 Ford E-150?

  A: Placing the vehicle in neutral position and hoisting it is the first step for servicing the 9.75-inch ring gear axle shaft assembly. Draining the lubricant requires removal of the wheel and tire assembly and differential housing cover first. Starting with the removal of the rear disc brake calipers you must place them securely out of the way before proceeding with brake disc removal. The next step requires removing the differential pinion shaft after removing its lock bolt and extracting it from its position. Be cautious when removing the U-washers by pushing the axle shafts toward the center because the rubber O-rings within the U-washer grooves are vulnerable to damage. Take care to extract both axle shafts by safeguarding the wheel bearing oil seal from damage. Apply grease to the lip of the wheel bearing oil seal then put the two axle shafts back while protecting the oil seal from damage. The U-washers need installation by positioning one on each axle shaft button end then extending the shafts outward. Insert the differential pinion shaft while fixing it into position by guiding the hole to meet the case lock bolt hole and fasten it using a fresh lock bolt. To finish implementation place the rear brake discs and calipers before securing the differential housing cover while adding required lubricant to the rear axle housing and reinstalling the tire and wheel assembly.
