  • 2006 dodge 1500 4x4 front wheel bearing replacement. Question: How do I remove the three bolts that hold the bearing in place? Do I have to remove the controls at the ball joints? I am not able to get a socket on the bolts because the axle shaft is in the way.

    Why don't you post this one in Answers so that we can get more people working on it. That venue is perfect for a one-time question like yours:

    then if you'd like to come back to Forums and talk to other Dodge truck owners, you can go here (save this link):

    Anyone know where I can get a copy of this TSB ?

    Also, anyone else had the check engine light come on, indicating (according to the dealer) that the knock sensor is not working properly ?

    RE: 2008 Lucerne CXL

  • scandiakenscandiaken Posts: 11
    Has anybody got a cure for my inability to read the instrument panel on the 2008 Lucerne in the daytime? I cannot believe that Buick has not put out a service bulletin on this problem. Surely there is a fix of some kind. Thanks for your help.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,416
    Which engine?

    Also that's not the nomenclature that the factory uses for TSBs. That must be some other website's tracking number, like I'm posting for the other member in the next post


  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,416
    this is the only TSB I found that even comes remotely close to your problem, but it doesn't quite sound like what you are experiencing. There's nothing else I can see on the list unless it's a brand new TSB just out:

    Bulletin No.: 02-06-03-008C

    Date: May 30, 2007

    Low Voltage Display on IP Gauge, Lights Dim at Stop Lights, Battery Discharged, No Start, Slow Cranking, Dim Lights at Idle, Low Generator Output

    1990-2008 Passenger Cars and Light Duty Trucks (including Saturn)
    2003-2008 HUMMER H2, H3
    2005-2008 Saab 9-7X


    This bulletin is being revised to add the 2008 model year. Please discard Corporate Bulletin Number 02-06-03-008B (Section 06 - Engine).

    Any vehicle may have a low voltage display (if equipped with gauges), lights that dim at stop lights, slow cranking, no start, low generator output at idle or dim lights at idle when electrical loads are heavy at idle or under slow driving or infrequent usage conditions. These characteristics may be more noticeable with customer added electrical accessories, or with a discharged battery. These are normal operating characteristics of a vehicle electrical system and no repairs should be attempted unless a proven fault has been diagnosed.

    During normal driving conditions, when engine speed is above 1000 RPM, the generator is designed to do two things:

    Supply the current necessary to operate the vehicle's originally equipped electrical devices (loads).

    Recharge/maintain the battery's state of charge.

    The following factors may affect generator and battery performance:

    Non-usage of the vehicle for extended periods of time. The vehicle's computers, clocks and the like will cause the battery state of charge to drop (For example; 30 days in a parking lot and the vehicle may not start because of a dead battery or a vehicle which is driven only a short distance once a week may end up with a discharged battery to the point where the vehicle may not start). This would be considered abnormal usage of the vehicle and the normally expected result for the vehicle battery, generator and electrical systems.

    At idle, vehicle electrical loads may exceed the low speed current (amperage) output of the generator and when this happens the shortfall comes from the battery. This will result in a drop in the electrical system voltage as the battery delivers the additional electrical current to meet the demand. This is equivalent to the brown outs experienced by homes and businesses when the electrical demand is more than the supply. See Figure 1.

    Extended periods of engine idling, with high electrical loads, may result in a discharged battery. Attempting to recharge a battery by letting the engine run at idle may not be beneficial unless all electrical loads are turned "OFF".

    Increased internal generator temperatures from extended idling can also contribute to lower electrical system voltage. As the generator's internal temperature rises, the generator's output capability is reduced due to increased electrical resistance.

    The table shown are some typical examples of electrical loads.

    Depending on the vehicle application, generator current (amperage) output at engine idle speeds of 600-700 RPM can be as low as 35 percent of the full rated output. With enough electrical loads "ON", it is easy to exceed the generator current (amperage) output when the engine is at an idle of 600-700 RPM. This is a normal condition. The battery supplements for short periods of time. Items that affect the vehicle's electrical system current and voltage at idle are the number of electrical loads being used, including add-on accessories, and extended idle times. When the vehicle speed is above approximately 24 km/h (15 mph), the engine/generator RPM is high enough and the generator current (amperage) output is sufficient to supply the current (amperage) requirements of the vehicle as originally equipped and recharge the battery.

    Dimming lights at idle may be considered normal for two reasons:

    As the engine/generator speed changes, so will the current (amperage) output of the generator. As a vehicle slows, engine/generator RPM slows, and the current (amperage) output of the generator may not be sufficient to supply the loads, the vehicle system voltage will drop and the lights will dim. Dimming of the lights is an indication that current is being pulled from the battery. If the battery is in a low state-of-charge (discharged condition), the driver will notice a more pronounced dimming than a vehicle with a fully charged battery.

    When high current loads (blower, rear defogger, head lamps, cooling fan, heated seats, power seats, electric "AIR" pump, or power windows) are operating or cycled "ON", the generator's voltage regulator can delay the rise in output. This effect, usually at lower engine speeds, can take up to ten seconds to ramp up the generator output. This is done to avoid loading the engine severely. To increase current (amperage) output, additional torque is consumed by the generator. The engine computer (PCM) will ramp up engine/generator speed in small steps so engine speed variations are not noticeable to the driver.

    For diagnosis of the battery and or the generator, refer to the appropriate Service Information or Corporate Bulletin Number 05-06-03-002B.

    Nope. That is not the problem us Lucerne owners are experiencing.

    In our case, there is no light at all on the instrument panel when
    driving without headlights during the day. It is probably
    exacerbated by the fact that the gauges are behind deep cylinders
    so the sun does not light them. When we turn off the engine,
    the lights light up wonderfully! I am quite sure it would be a small
    circuit board fix, if only someone would just develop it or identify
    it as being available.

    At night the dash lights are fine, and the reostat that adjusts them
    works just fine. I think it was just a design oversight.

    Thanks for your attempt to help.

    For a temporary fix could you turn on your parking lights?
  • 0patience0patience Posts: 1,542
    There is a new high contrast intrument panel for your vehicle.
    If it is still under warranty, the new I/P should be covered.

    See this bulletin:

    Instruments - Difficult to View Cluster in Bright Light
    Bulletin No.: 06-08-49-021A
    Date: December 05, 2006
    Difficult To View Instrument Panel Cluster (IPC) Display When Driving Toward Bright Sunshine (Replace Instrument Panel Cluster)
    2006-2007 Buick Lucerne (U.S. and Export)
    Certain VIN breakpoints (see dealer)
    This bulletin is being revised to update the table of IPC part numbers. Please discard Corporate Bulletin Number 06-08-49-021 (Section 08 - Body & Accessories).
    Some customers may comment that the instrument panel cluster (IPC) display is difficult to see when driving toward bright sunshine.

    This condition may be caused by an insufficient color contrast in the IPC display.

    Technicians are to install a new IPC with a display that has improved color contrast. Refer to the Instrument Cluster Replacement procedure in SI for more information. The original IPC part number may be obtained using a Tech 2(R).

    That sounds good. I will definitely share that info with my Buick Service Department.

    I am afraid it is too little to correct the problem, however. As far as I can tell there is NO ILLUMINATION on the instrument panel when driving without lights on. Turning the parking lights on halps a little (here is where the contrast could be inproved (I would say the lights should be brighter)). When the parking lights
    are on, the running lights go off. If the running lights are a safety factor, as I was
    led to believe, they should be on when driving.

    Thanks for the information.

    Is there a TSB that deals with headlights shutting off (ONLY in high beam mode) when turning on right turn signal?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,416
    No I checked the list on ALLDATA, including new entries, and nothing like that.


  • ray80ray80 Posts: 1,233
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,416
    That's a multi-function switch isn't it? (works directionals + lights?) If so that's where I'd look .


  • ray80ray80 Posts: 1,233
    Yes it is one of those 'does everything but butter your bread' switchs, and is most likely the culprit. I just don't want to replace it only to find the problem is some strange electronic malfuntion or due to streching a wire when in hi-beam mode. (plus of course it only happens once in a whle)
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,416
    Well you'll spend as much time and money on a wire by wire diagnosis as you would taking a chance on this switch, seems to me. I hate to encourage "guessing" but in electrical matters, sometimes an educated guess is the best course IMO.


  • Thanks for the informative post on the p1811 shifting problems!!! very helpful!

    I found a TSB on, but how do I get the details of the bulletin?

    Bulletin Number: 111000
    Bulletin Date: Oct 2000
    Vehicle: 2,001 Chevrolet Cavalier

  • 0patience0patience Posts: 1,542
    Its an NHTSA number, so you will likely have to play their game to get the info.
    It isn't in the manufacturer's database, so it is one of those numbers that NHTSA has pulled out of thin air.
  • Hi All,
    I am a new user to this site and just logged on tonight so hi to you all.
    Please can anyone help?
    I am in the UK. I have a 2002 Thunderbird. I just love it and it is a rare beast over here. Can anyone suggest where I can get a service manual from All traces so far have prooved fruitless. Haynes do not seem to do one. Do I have to go direct to Ford?

    Can anyone tell me how often the recommended service should be?
    What oil do you suggest.
    What air filter is best.
    It seems to "Smell" hot after a few blasts but not temperature wise. anyone know of any issues.
    Have been told to fit cool air intake . Any comments would be fantastic as you guys over the pond certainly know how to build your cars.
    By the way I am a total novice at all this - and even worse - I am female !! :D So I need all the help I can get. :confuse:
    Look forward to your comments.
