So far, this is the most annoying problem on the Pathy. There is a TSB on it. Can one of the members post it here for everyone's sake. Thanks.

Oh yeah, I'm first here.

    NTB/TSB for shimmy by smithmd  Jan 05, 2001 (03:20 pm)

    Here is everything about the shimmy. I found my old post. I'd actually saved it in a text file on my PC just-in-case. I'm still shimmy free. Now the other old post:
    I just got the Nissan Service Bulletin I had
    mentioned. It's 11 pages and includes and lot of
    stuff, so I won't attempt to reproduce it on this
    page. I will say that on the flow chart, the first
    question is, "Is this vehicle equipped with Nissan
    OEM wheels and tires?" If the answer is no, such
    as if you have already replaced the tires, the flow
    chart states, "This Technical Service Bulletin and
    Nissan Warranty Coverage do not address vibration
    that can be caused by after market products or
    modifications." Even though you've replaced your
    tires already, you might ask your tech to print you
    off a copy of this NTB.
    I remember some folks talking about having their
    wheels chromed. The next question in the flow
    chart is, "Are the Nissan OEM wheels aftermarket
    chrome plated?" If the answer to this question is
    yes, you get the same response as the guy that has
    already replaced his tires.
    Nissan Service Bulletin
    Classification: ST99-001
    Reference: NTB00-061
    Date: July 18, 2000
    1999.5-2001 Pathfinder steering and/or body
    Applied Vehicles: 1999.5-2001 Pathfinder (R50)
    Service Information
    If a 1999.5-2001 Pathfinder exhibits steering
    and/or body vibration while driven (without
    braking) at speeds between 60 and 70 MPH, the
    cause(s) may be:
    - Road input (road surface imperfections)
    - Out-of-balance front or rear tires/wheels
    - Insufficient steering rack sliding force
    - Tire flat spotting
    - Excessive tire Radial Force Variations (RFV)
    The last part (RFV) is where they look to index or
    match balance your tires and if that still doesn't
    work, they replace your tires.
    Hope this helps.

    I figured I would post this here also. In the last 1000 or so starts in my 2001 PF LE, I once had a situation where it didn't fire up in 2 tries (didn't even cough). I finally depressed the gas pedal a bit and cranked and she fired up like there was no problem. No problems since...but kind of weird for a truck that usually starts and runs so well.

    I'm at 3400 ft in Calgary, but the truck was in my heated garage. It also hadn't been used for a few days and the weather had warmed up considerably. I'm wondering if maybe it was just condensation in the tank? Anybody else have this problem?
  • phil47phil47 Posts: 394
    While I'm at it, I've noticed this truck can give you quite a kick when downshifting from 2nd to 1st, even with moderate acceleration. I think I also get a good kick from 3rd to 2nd. Anybody else notice this or think it's an issue?
  • So far (7500 miles) I have only one issue with hard starting. My Pathy was outside in the cold with the nose pointing down in the driveway (10-15 deg incline). It so happened that I didn't have my gas cap on as well. It did start after the second try though.

    If you are indeed worried about condensation, then try dry gas. I had that same issue with my 300ZX TT and dry gas worked beautifully!

    Mine was like that too. After I passed 7000 km it kind of smoothed out. Just for the record, jerky shifts on an auto are actually a good thing. The trans. actually lasts longer when it does this (less slipping of the clutch packs). At least that's what a transmission engineer told me a few years ago. To be on the safe side, check your trans. oil level.
  • phil47phil47 Posts: 394
    I've heard that too. Crisper tranny shifts (less clutchpack slippage) is one of the first upgrades that's recommended if you boost engine HP by supercharging, etc. Maybe this is one of the mods made to the new drivetrain with the increased HP of the VQ engine. Anyway, it's nice to hear it smooths out eventually (and I will check my fluid level). Thanks.

    I've started using an injector cleaner that also works as a gas dryer (kill 2 birds...blah, blah). Probably the best thing I could do is not let the tank run below 1/2 when it's cold outside (hard to do when this truck only lets you go 200 km on a half tank!!). I hope this prevents that problem again. Your situation sounded like it could be condensation related also.
  • I posted this in the main area too, but it's more of a problem that needs a solution, so I'm posting it here.

    Anybody with the shop manual:
    What does it say about the adjuster for the rear drum brakes? In post #503 in the main area, meca2 talks about turning this star-shaped wheel inside an access hole to tighten the brakes. I did that, but now it seems like my parking brakes are too tight, and don't disengage all the way! Is there any way to undo this? Please say yes, and tell me how!

  • I was right, the parking brakes were too tight. That star wheel tightens the brake pads against the drum as you rotate the wheel inwards. I had tightened them too much, so then the pads were dragging against the drum! (Yikes!)

    So I brought it to the dealer, and the mechanic simply loosened it by pushing in on the retaining lever by using a thin, bent screwdriver. As he released the lever, he was able to ratchet the star wheel back notch by notch.

    It worked, and when he was done my wheels spun freely once again. Of course, now the pads are a lot closer to the drum than they were before, and that translates into less travel before the brakes engage (feels better).

    Moral of the story: if you do adjust the brakes manually, do not overtighten the self-adjuster wheel! If you do, you'll have to do the thing with the small screwdrivers.

    Or, see meca2's post in the main area. There's a way to adjust the brake under the lever.

    BTW, the mechanic told me that the self-adjuster mechanism works by pulling the parking brake lever. It doesn't work on the back-up principle like other cars.

    I can't wait until my manual gets here.

    aspenwhite: The PL14620 oil filter is used in the later Altima (2.4L) and I'm
    sure other cars. The Purolater book says to use L14612 and does not show
    a Pureone filter for the PF engine. I compared the two at the auto parts store
    the L14612 has a spring and what looks like a extra bypass valve or something
    that the PL14620 does not have. I have disassemble filters from my other
    Nissan cars I've had over the years and have never found any metal or anything else
    in them. I would be concerned about oil flow through the filters?? Bigger is some-
    times not better!!.........Just a thought.....Steve
  • meca2,
    Both the Pathfinder & Maxima use the same oil filter (OEM: 15208-9e000, AC-Delco: PF2057, Motorcraft: FL-821, Mobil 1: M1-110, Deutsch: D370, Bosch: 3323, Fram: PH7317, K&N: HP-1010, Luberfinder: PH-2867, etc) ONLY Purolator is listing two different filters, the L14612 for the PF and L14620 for the Maxima. The L14620 (and PureOne PL14620) is actually the same size as the genuine Nissan 15208-9e000. I have no idea why they list the L14612 for the PF. Any thoughts? TIA
  • I've just had my 2001 EL WAD for a couple of days and noticed the transfer case leaking fairly profusely. I'm taking it back to the dealer tomorrow. Anyone else have this happen?
  • Hi guys!
    I'm changing out the water pump on an '86 6 cyl pathfinder in a day or two and while I'm at it I'm going to change out the timing belt as well, since it has to be removed to reach the pump . I can't find a repair manual anywhere so I don't know what to align the valve gear timing marks up with. Does anyone have an answer. Thanks ------------ Jeff
  • I believe you are the first to post such a problem. I have been following this and other various PF postboards since 3/00. Good luck with the fix.
  • Turns out that my transfer case leakage was an improperly sealed threaded plug on the top. No problem.

    The only problem that I have now is that the gas gage goes down at the same rate that the tachometer goes up. They must be linked.
  • Yes. I think there is a string tied between the two. Wonder if I cut the string if I could get better mileage?

    Some have commented about the auto seat doesn't move after the key was turned. I noticed that if the seat is moved manualy first then the key is turned the seat does not move automatically forward or backward until the key is removed and inserted again. For what it's worth...... Steve

    I love my PF, but the factory alarm is a PITA. I never set it because it will invariably go off when I enter the truck or else trigger if I leave the truck unlocked. Well, today the #$% alarm went off at work and it was NOT turned on. The Nissan service manual is silent on the alarm system so I am at a loss. Does anyone know how to disable the alarm without killing the interior lights and/or the keyless entry? TIA.

    Hello, I recently began hearing a faint whistling noise coming from the back end of my 98 Pathfinder SE. It has an automatic transmission and is 4 wheel drive. I start to hear the noise above 35 mph; it becomes more noticeable as the speed increases. The noise is only present when I have power applied. If I let off or coast, I do not hear it. As I mentioned before, it is a very faint whistle. This may have nothing to do with the problem, but I hadn't noticed the noise until after I had new tires installed. One other thing, I have noticed a rotten egg smell as I exit the car after parking it in my garage. I do not smell it when outside, only in the garage. The car has 59,000 miles. Other than the problems I have just noted, it runs and drives excellent. Any Ideas on these issues would be greatly appreciated.
  • meca2meca2 Posts: 284
    kraigp: What brand of tires did you install? Some have noisy tred. Check the tire pressure?? And tire size, all have to be the same? Some winter fuels are blended different for the area you live in and do smell like rotton eggs. Try a different gas station next time you fill up. Just a thought. Steve
