tbooth2 - "drone-whine sound during cruising speed (40-70 RM, I take my foot off the pedal and it stops)" --- this sounds exactly like ring and pinion gear whine in the rear differential. Mine had it. My service tech has had issues with new differentials coming from Ford already misaligned and whining. He insisted on ordering the parts and rebuilding my current differential himself. He grew frustrated with not knowing what he was going to get with a new differential. Worked like a charm, no more problems.
dkovach- it is possible that your issue is the rear diff and you just got another bad one. You mention noise that goes away when switched to 4WD. Did you mean 4Auto or 4HI? There is a TSB on front differential whine/groan when in 2WD that goes away when switched into 4Auto. Is there a loud clunk when you switch into 4Auto while moving? Your front halfshafts could be spinning opposite directions and the cluck ocurs when they are forced so spin in the same direction when put into 4Auto.
Vibration at freeway speeds. There is a TSB for this also. Ford produced a troubleshooting flowchart for the problem. After ruling out the wheels or tires through various procedures, if the vibration still exists, the TSB says to replace the steering gear. I have also heard of others solving the problem by having the rack and pinion replaced. That is not mentioned in the TSB, however.
Now if anyone gets their doors to stop rattling please let me know the solution. I am on my third set of redesigned, and supposedly improved, gasket kits for the doors. Mine is actually worse now than it was before.
Try flatratetech.com for help from Ford service techicians. This is where I got help for all of my problems.
Hopefully this helped someone a little bit.
Nvbanker, I've never heard of this early vs. late VIN typology on Navigators. Does it only apply to Expy?

312--having the same rubbing noise on my 03 Expedition from time to time. Sounds like tires rubbing or maybe something that need some grease in the steering column. Don't know?
316--with Navigator sales steady in the 3,500--4,000 range, the entire year's production would
be well within the 99,999 available. Thus all would be "J" production? Would it work to divide
your 19121 "J" number by 3,500 monthly produced/sold to arrive at 5-6 months into the production year? Worked for me relative to MM back in the late summer when we were looking for early "J" 2003 Mountaineer inventory on the Mercury and Ford/Mercury websites.

03-19-8 STEERING - LIMITED SLIP AXLE CHATTER, SHUDDER, BINDING SENSATION, OR VIBRATION DURING LOW SPEED TURNS
VIBRATION - LIMITED SLIP AXLE CHATTER, SHUDDER, BINDING SENSATION, OR VIBRATION DURING LOW SPEED TURNS
AXLE - LIMITED SLIP AXLE CHATTER, SHUDDER, BINDING SENSATION, OR VIBRATION DURING LOW SPEED TURNS
FORD: 2003 EXPEDITION
LINCOLN: 2003 NAVIGATOR
ISSUE:
Some 2003 Expedition/Navigator equipped with the 9.75" or 8.8" limited slip rear axle may exhibit chatter, shudder, a binding sensation, or vibration during low speed turns. The sensation may appear to originate from the front axle, or the steering gear.
ACTION:
To service, first verify the condition. With the vehicle at cold startup. Ensure that the vehicle is in 2WD, to isolate the rear axle. Turn the wheel fully right (or fully left) and then accelerate the vehicle. If the condition is verified to be in the rear axle, replace the limited- slip clutch pack.
fx4 - I think there is a TSB for the body cladding. I believe I came across it on the NHTSA web site.
My dealer finally got my steering wheel nibble to go away. Fresh set of skins took care of it. Too bad it took a combined total of 7 days to figure it out.
In other applications I have used Raybestos Quiet Stops which solved the problem as well. Some people have indicated they have gotten them for their Expys but my local shop says they aren't available for the '03 yet. I haven't had time to look inot it further.
I have had the same problem since I purchased my car in May, 2003. I had the rear differential completely replaced in July, to turn around 6 weeks later with the same problem. In July
Ford said they had narrowed down the problem to the clutch packs and they were replaced. Now November and 7 weeks later, the grinding sound is back. My dealership said Ford has now definitely figured out the problem; the last clutch packs were only a "temporary fix' and there is a national backorder for the "newly designed clutch packs" which will be placed on my car as soon as the dealership gets them.
Am I being snowed or have any of you gotten the same story? All I know is strike three and I want another car.
Thanks
Any thoughts on this or are the problems the same?
On other vehicles, I've used PIAA Super White bulbs, which put out more light than the Sylvania's. Some people complain about their short life, but mine lasted the year I had the vehicle before I got rid of it. On my replacement vehicle, I've installed Sylvania SilverStar's ($20 each at AutoBarn.com) and I'm quite pleased with their output.
If aimed properly, the new bulbs should not blind oncoming drivers.
I was wondering if anyone has heard of any similar issues. I did a search but didn't see any. I'm well aware what 3 yr 36K miles means in warranty terms but come on. This truck has been well cared for and is only 2.5 yrs old.
The lenses are clean already, so its probably the lamps.
