Hello! I've just bought a 2004 Expedition EB with 5.4L Triton, about 92k miles. I've noticed that the axle whines when engaging accel or cruise, esp over 60 mph. Axle noise stops when coasting.
Doing some reading, I've learned that this is a very common problem for Exp's of this era. Also noticed that there's a TSB describing an apparent fix for axle whine.
Does the TSB fix really work, in your experience? Or am I going to be back in the shop repeatedly for more rear axle work?
We want to tow a 5000 lb trailer so it needs to be a reliable, safe rig. Can't afford a garage queen, not out of warranty like this.
I have taken it to the local Ford dealer, who wants to charge $900 labor and $1075 to do a rear axle teardown and diff overhaul.
They also found some noise in the right rear wheel bearing, which they'll fix for $110 labor and $312 parts.
Are these fair costs, and will they fix my issue? Thanks.
1) Where would you recommend ordering this rebuild kit? Do I just reference the TSB and the shop will know what I need?
2) Labor is rated 5.9 hrs for the TSB kit install, so you think $600 labor sounds right?
3) Is the TSB fix going to fix my right rear bearing issue as well?
4) Would you think with this kit installed, I'll experience further issues with the rear end? IOW, does the TBS solution really FIX it? I really need to be able to trust this vehicle.
