    Any one out there have power running boards that don't deploy every time. Its unsafe and my dealership have had half a doozen goes at fixing it so far?
  • I have the 2003 with the tilt down mirrors. I love them but have had them worked on and replaced five times. First one then the other. After they would tilt down they would not return to the proper position. At 19000 miles I have just had the rear end replaced. I would get a whine at about 50 when I would accelerate. Had to wait almost a month for parts. Seems to have solved the problem.

    Has anyone out there driven an '04 and '05? Does the '05 engine make any real world difference (smoother, quicker) or is it just marketing hoo-ha?
  • ANT14ANT14 Posts: 2,687
    Ohhhh yes, much smoother and quicker. You receive the 3V version of the 5.4L that debuted in the '04 F-150. So you receive equal hoursepower, and improved torque, while using regular gas. The 6 speed automatic transmission is a segment first, same one sourced from Jaguar.

    I've had -0- problems with any of the running gear on my 03 Navigator, and only very minor issues with some of the doo-dads. But the tilt-down in reverse mirrors have been flawless on mine, and I'm over 21,000 miles now.
  • gteach26gteach26 Posts: 576
    I guess I'm just gonna HAVE to test drive an '05 when my lease is up this December.

    I wonder if it'll impress me to the point of wanting to stick with the gator for a couple more years. Smoother, quicker, no more flapping molding (I HOPE), improved sound system... we'll see.

    Also, I'm hoping in late December Lincoln will be "giving" these luxo busses away like they are now ($6,500 in total factory rebates -on top of the best deal I can get through my dealer -- that's what's being offered for me to get out of my lease right NOW and into an '04). I don't want an '04 though, and the three lease payments I have left eat up too much potential savings... I'd rather wait.

    Decisions, decisions!!! :)

    Thanks ANT.
  • nvbankernvbanker Posts: 7,285
    My dealer has some 05's on the lot already, along with a boatload of 04's. I drove one. I was impressed. Seemed tighter, more solid, smoother, quieter. Didn't notice any difference in power, but then, I don't have a problem with that anyway, mine seems to have plenty now. Maybe you can get an 05 now.
  • gteach26gteach26 Posts: 576
    ..are "only" $1,000 at the moment according to the offer sent to me.

    I really hope I can tell a difference with the new engine.. my 03 navi just doesn't run as smooth as I'd like it to. I guess I want the impossible in a vehicle this large... an ultra-smooth, tight, and lightning-fast/responsive isolation chamber while on the freeway.

    I guess vehicles this large will always have their trade-offs.
  • ANT14ANT14 Posts: 2,687
    Let's also take note, sometimes we believe vehicles are less responsive, slow, because of how quiet they really are. The new 3V 5.4L coupled with the 6 speed automatic will jolt you a bit on your seat once you first press the accelerator. Maybe that jolt might make some perceive it as being a bit more stronger.

    Plus the old 4V version require you to work the accelerator harder to make it breathe higher, which allowed it to gain it's power up high. This new version will not need to work as much, hence, Better fuel economy.
  • nvbankernvbanker Posts: 7,285
    Well, with gas prices going up, up, up, I'm not offended by being able to fill up with Regular again. That's for sure. Anything else will be a bonus.
  • ANT14ANT14 Posts: 2,687
    Ok, the beast will continue to require premium fuel. Urrrr It has to do with improved emissions/diagnostics, while allowing it to post better fuel economy.
  • akirbyakirby Posts: 8,019
    I was wondering about that myself. It may put out more than 300 hp on premium. Ford has been underrating their high hp engines lately. The 300 hp mustang GT appears to be closer to 320.
  • ANT14ANT14 Posts: 2,687
    Could be an insurance reason, hmmmmm.....
  • nvbankernvbanker Posts: 7,285
    Oh, drat! Budget revision time again....

    But does this mean this same engine in an Expedition will require Premium as well??? And if not, what the heck is going on? Same engine, isn't it?
  • ANT14ANT14 Posts: 2,687
    Same engine, same output numerically. The Expy and F-150 require regular. The Navi will require premium because of other components, I'll explain later.
  • nvbankernvbanker Posts: 7,285
    OH brother! You pay to play, evidently..... Well, please do explain, because I'm facinated by this, and it's looking like I'll be owning an 06 Navigator at this point. Can't resist the "Red Carpet" it seems......
  • akirbyakirby Posts: 8,019
    It's all in the tuning, especially timing and compression ratios. Higher compression ratios and advanced timing require higher octane to avoid knocking.

    My Aviator has the 4.6L 300 hp and requires Premium but the Explorer 4.6L does not. But it only makes 260 hp.

    There could be some other reason also as ANT implied.

    But let's get real folks - you're talking about $3-$4 per week on average. You probably waste that much on soda or bottled water or coffee or junk food. And it's the same price difference regardless of whether regular is $1.49 or $2.49 - it's still a difference of $0.20 per gallon.
  • ANT14ANT14 Posts: 2,687
    Actually the Explorer makes 239HP with it's SOHC 2V setup slightly different design than the Aviator which has a DOHC 4V which was the same engine the previous Mustang Cobra (320HP), and Mercury Marauder (300HP) had. Which explains the premium gas, to extra the full potential of the engine and increase compression.

    Next year Explorer receives the 3V version of the 4.6L that's debuted in the new Mustang.
  • akirbyakirby Posts: 8,019
    I think I got the explorer V8 confused with the 4.6L Expedition which does make 260.

    Just goes to show you there's a lot of room for tuning an engine. That's over 80 hp difference for the same displacement. Not counting superchargers.
  • ANT14ANT14 Posts: 2,687
    Expedition's 4.6L also 2V SOHC makes 239HP as well, (same as the Explorer). The 5.4L 2V was the one that made 260HP. Don't confuse it with the 4.6L in last generation's Mustang that made 260HP, but from a 4.6L 2V (tuned differently than the Explorer).

    This year in the Expy, it loses the 4.6L, and the sole engine will be the 5.4L 3V making 300HP, same one as the F-150.

    Usually when you DOHC a V8 engine, you can extract anywhere from 25-40HP (more if you increase the compression which would require premium). And when you place a full dual exhaust system, you can gain 10-20HP approx. (difference between the Explorer's 4.6L and Mustang's 4.6L).

    Interesting note: there's very few (if any) DOHC V8 engined passenger cars under $30K. In fact, I believe the Marauder and Mustang SVT Cobra were some recently departed one's. (Not couting trucks/SUV's since those make higher profits in their less complex engineering, that offset the engine cost).

    The new generation of 3V's 4.6L, 5.4L and 6.8L allows the engine to accomplish DOHC power, with better fuel efficiency, less complexity, and less cost to build. Hence, why 3V will/has replace/d Mustangs 4.6L, Explorer 4.6L, Expy 5.4L, Navi Intech 5.4L, etc.etc.
  • akirbyakirby Posts: 8,019
    I knew ONE of those engines somewhere made 260 hp.

    And I had a 5.4L expedition so I should have remembered.

    Thanks for setting the record straight.
  • ANT14ANT14 Posts: 2,687
    Even my brain Rolodex has a hard time keeping up with them, which is how I made the mistake on saying the Navi engine would take regular.

    But yes, the 260HP 5.4L, originally started at 230HP when it first debuted in th Expy back in 97-98. Through the years it has grown in performance, and as seen in the GT (4V), it can produce 550HP with a Supercharger.

    Each application is different, and tuned different. Which explains why the Mazda6 3.0L makes 220HP, not like the 500's 3.0L, and why the Ranger's 2.3L I4 is rated at 135HP when the same engine makes 160HP in the Mazda3. etc.etc.
  • nvbankernvbanker Posts: 7,285
    but you're skirting the question I asked, which is again:

    Why does the 05 Navigator require Premium, if it has the same engine as the Expedition which requires regular, and produces the same HP output? It's not that I mind paying for the Premium, and I always do, btw, I just want to know with the 3V - what's the difference between the two applications for 05?
  • ANT14ANT14 Posts: 2,687
    It deals mostly with emissions, computer programming, new transmission. When I receive a detailed explaination that I'm happy with, I'll share.
  • nvbankernvbanker Posts: 7,285
    Ok, ANT. I'll be here. Meantime, I love my Navigator more with each mile driven. This is one amazing vehicle.
  • Well, my husband has walked out on me and the kids after 17 years of marriage :(
    My "parting gift" is that I get to purchase a new vehicle before he leaves to replace my Ford Explorer. It was an older model that accelerated on its own, going up to 100 mph before I panicked, hit the brakes, & caused it to flip over 7 or 8 times.
    I mention these two things because A:) I dont TRUST vehicles as I did before and want something I can feel safe in and B:)I dont have that "Manly advice" you can get from your husband about which vehicle to pick-LOL.
    I've picked through many old threads here as fast as my VERY OLD COMPUTER & MODEM will allow but cant seem to find a "great" reason to pick the Aviator or Navigator over each other??
    I see "whining noise" mentioned on the Aviator, not enough "Power" on the Navigator.....

    It would be nice to have a quiet vehicle. I am very short, myself, only have two kids, and now, no husband, so I dont NEED the larger Navigator....

    If my finances will allow either a 2004 Aviator or a 2003-2004 Navigator is there any definitive reason to favor one over another?

    Are there many features that are not in the Aviator that make the Navigator more "worthwhile?"

    I obviously would love the Roll Stability feature because I have no desire to watch the world go upside down again but it seems that feature is hard to find?

    Lastly, and this question may yell out "Car Ignorance" but why is it that the MSRP for the 2005 Aviators is not much more than the 2004?

    Thank you in advance for your help. I hope someone can post just the right remark to help me make a decision one way or the other. I just know they are both GORGEOUS on the inside and if I need to replace my car I want to be looking at that Gorgeous polished Nickel!!!

    Plan to get '05 Nav, Ultimate and was told by a neighbor who has '04 Nav, Ultimate 4WD that there is something stronger about the front suspension (I think) in the 4WD version of the truck than in the 2WD version. He said that this component (again, I think he said the front suspension, but I'm not sure) is less robust in the 2WD version and will ultimately cause the front of the truck to be lower than the back--giving it the look of "nose-diving" after awhile. This info is bad news for me because I didn't want to shell out for 4WD since I won't be needing it in our climate/driving situation.
    Does anybody have any info to offer before I make my decision on this potentially important issue? Thanks!
  • akirbyakirby Posts: 8,019
    Your source must be talking about the front springs and yes, they're stronger in the 4WD model because there is more weight to support. I have not heard of recent Navigators having a problem with front springs so I'm not sure where that concern comes from.

    I would not hesitate to go with 2wd if you don't need 4wd capability. There are far more parts to worry about that are more serious than a droopy front (which I'm still not sure I believe).
  • nvbankernvbanker Posts: 7,285
    Well, since the truck has load leveling and air springs at all four corners, monitored for accurate height at all times, I can't see how the 2WD could be at risk for a problem, but mine is a 2WD, is a year and a half old, has 22,000 miles on it, and it's just fine. I've had no drive train or suspension issues at all.
  • ANT14ANT14 Posts: 2,687
    In the majority of 4WD vehicles, chances are the suspension components differ from their 2WD counterparts mainly because of the increased weight they must carry and stress placed upon those parts, hence, they are of quality to match what they must sustain. Easily, a true 4WD system will add anywhere from 300-450lbs to a vehicle. In the opposite spectrum, we have examples like Haldex AWD systems (which turn on ONLY when slip is detected over the driver wheels) that might add 150-200lbs to a vehicle. Gotta pay, to play.

    As for the nose diving, it has to be completely dramatic, full body weight thrusting upon the brake pedal to cause such an action. And if so, it levels itself quickly and will hardly be detectable to anyone or the driver. We aren't talking about the nose diving, chin scraping nose diving commonly found on Caddy's, Buicks of the 70's either. And if the actual driver of such a vehicle is able to accomplish that in such a vehicle, they should have bought a sports car, NOT an SUV.
