Ford Explorer Rear End Whine/Hum
TSB 05-12-6
TSB 05-12-6
Vehicles:
2002-2005 Ford Explorers
2002-2005 Mercury Mountaineers
Issue:
Some vehicles listed above may have a whine/hum during acceleration, deceleration, and/or cruise.
Action:
Use axle repair kit to fix the issue. This kit should be used instead of installing a complete rear axle assembly. Replace the Ring and Pinion and it's components.
NOTE: When servicing the rear axle on these vehicles, replace the 75w-90 gear oil with 75W-140. If the axle is equipped with a Limited Slip, add the required amount of friction modifier (XL3). When replacing the fluid, replace metal tag with F3TZ-4121-AA tag.
Kit Part Numbers:
- 8.8" 3.55 Gear Ratio - 5L2Z-4209-AA
- 8.8" 3.73 Gear Ratio - 5L3Z-4209-C
Time: 6.6 Hrs for Explorer/Mountaineer
