    Huh? You need to cool off before you post, I had to read it 3 times to understand it.

    You know those 4.10 gears, AWD, and 400 hp combined with 4 speed auto = 12mpg I would guess.

    If they had utilized a beefed up 5L50E 5-speed automatic from the Caddy SRX rather than a "new" 4L70E 4-speed tranny, they could have gone with 3.55:1 gears, had almost equal low-end torque multiplication to the wheels from the higher numerical ratio 1st and 2nd gears in the 5-speed, and get good highway MPG in OD.

    Then there's that weird box-looking single exhaust tip. You'd think they would have learned that lesson from the flop 2004 GTO. What happened to dual exhausts exiting out through the rear bumper fascia on the Trailblazer SS concept that's been shown for the past 3 years?

    Hey there!

    I have a 2002 Bravada with 54000 miles on it and it's in the shop again having the same repair done on it that was done at 40,000 miles. There is something going on with the transfer I am told.

    Symptons - When I turn to park the vehicle it feels as if the drive shaft is binding up and the vehicle stops rolling forward without me putting the brakes on. The same thing happens when I put it in reverse. It also makes a howling noise (similar to a low fluid in the power steering noise...I don't know how else to describe it) when I turn it and feels like it wants to lurch.

    The first repair involved tearing apart the transfer case and replacing internal parts as well as the rear pinion bearings.

    The second repair has involved (so far) the replacement of the transfer case encoder, replacement of a u-joint and resealing of the transfer case.

    I am at my wits end because after this second "repair" it's much worse than it was before I took it in.

    The mechanic is giving me some story about calibration of the module, and shims blah,blah,blah. But I have a feeling it's more than that.

    Any input would be great!

    PS. wade in on the extended warranty topic...I would highly recommend buying it. So far these repairs have cost me $200 when they could have cost me $4000.

    Thanks for these bar link numbers,tblazed. Did you put these on your vehicle and, if so, how do they work?

    Question: Would you or anyone else out there happen to know the diameter of the front sway bar on the '04 Envoy and the size of the mounts? I tried crawling under mine to measure them, but it's not the best way to get accurate measurements. The following retailer has urethane mounts for the Envoy, but you need to know exactly what size to order.

    Not installed yet- I have them here "in stock" ready to go someday when my originals start getting loose and noisy.

    I had the same problem on my '02 Envoy at 10,000 miles and told the dealership something was loose in the front suspension, they could find no problems. Then at 15k, 20k, 30k, the same diagnosis. When I went back at 40K they miraculously found it and replaced only the right side and the left one had the most play, right after my 36K warranty went into my extended warranty with a $100 ded. Get this, after 4 comebacks at 2 dealers they wanted me to pay for the sway link, man was I mad as a hornet! I went in for my taillight recall at the same time with a 2 week notice for the appointment and when I went to pick up the truck the receipt stated they had to order the circuit board for the taillight which the recall was for in the first place. Where has the customer service gone?? As for the link my words of wisdom to my service writer got me out of the bill but it really got my blood pressure up. So before your initial 36K expires get every little squeak, rattle, or problem on paper because murphy's law is for real.
  • ficussficuss Posts: 541
    This is why I have been encouraging others to go along with the service writer on the test drive. Make sure they go over the same bumps you do when you hear the clunking. I think GM has good and honest dealers, they just have to be prodded to see the problems.
    And I agree, Murphy's Law was written with the triplets in mind.

    "Question: Would you or anyone else out there happen to know the diameter of the front sway bar on the '04 Envoy and the size of the mounts?"

    The dia. on my '03 Envoy is 44mm. Many of the mounts have elongated holes thus will fit a range of sizes. You should be able to get close with a ruler and eyeball.
  • slipkidslipkid Posts: 10
    you are talking about the ride being on 4HI?

    this happens to me also, it's annoying but other triplet owners here at work have the same issue.
    Still works like a champ on the roads but a biatch to park. Was told it's not a major problem so no one was bothering to have it fixed.
  • bobfishbobfish Posts: 48
    I think the 04 Envoy front sway bar was changed so it is different from eairlier Envoy's.
  • My 02 Olds Bravada has the air ride suspension in the rear. One side does not inflate as high as the other side. It does't seem to go down during driving but does not go to the same level as the other side. Is there a sensor that may be bad that can be replaced? Is there a way to get them to level out by adding air manualy or do I need to go to the dealer?
  • 01_hoe01_hoe Posts: 273
    Each side has its own sensor. Sounds like a trip to the dealer, as no way to manually add air.

    Has it always done this or is this a recent notice?
  • I have just noticed this recently, but just purchased the car used so it could have been that way when I bought it and just didn't notice it. I hate to go to the dealer and spent $95.00 an hour for something I could fix myself. I suppose sensors aren't to friendly to replace!!

    With gas prices going up everyday, I decided to change the air filter in my '03 TB with 19,000 miles. Went to Auto Zone and picked up 2 Purlator air filters for TB's (my wife drives an '04), and an air filter for our '04 Corvette.
    The guy rings it up and says the total is $53.68. I asked how much were the air filters??? $9.99 for the Corvette and $19.99 each for the TB's. I asked are you sure???? He looks in the Fram book and says yep, same price listed for both. Is that what everyone is paying for an air filter???
  • ross1962ross1962 Posts: 229
    Sounds kinda steep! But I wouldn't know how much they are, as I have a K&N filter. They last about 50,000 miles, but you have to clean and re-oil them as frequently as you would ordinarily change a conventional filter. You can get one for as low as $50. It will eventually pay for itself and give you better performance.
  • ndmike88ndmike88 Posts: 155
    I know about K&N's, used them in my Mustangs. Just remember to remove them if you go in for service. They have been known to mess up the MAS. As for the "better performance" I'm not so sure. I never noticed any better performance. But you are right, they are cheaper in the long run.
    Today I went to Pep Boys and NAPA and they were all the some price--$19.99 for a standard TBair filter.
  • If you go back to message 15029, there are several messages regarding this problem, including what I did to correct mine on message 15071.

    Whoever told you that it's not a major problem needs their head examined!

    The first go around with this a year ago ended up with having major parts of the transfer case and rear pinion bearings replaced....

    This second go around ended up having the transfer case encoder replaced (which GM knows is failing!), the U-joint replaced, and the transfer case encoder motor (which AGAIN...GM knows is failing!) replaced.

    I picked it up today after the dealer having it for a week trying to find the problem (up to and including trying to tell me that it was the tires causing the problem!).

    How I got it fixed properly was I ended up asking the mechanic to find another vehicle on the lot that was comparable to my Bravada. Boy did I luck out! They had the same exact year, make and model (right down to the same color!) that I took the mechanic in for a spin around their parking lot. Making the same sharp turns as I did with mine. What do you know! NO BINDING UP! It finally dawned on them what exactly was the problem and that I wasn't some crazy woman complaining about "normal binding". (I'm sorry...binding in a vehicle is NOT NORMAL! No matter what your mechanic is telling you....something is wrong!)

    Well they finally figured it was the transfer case encoder motor, which they replaced and presto! No more binding, turns tight corners smoothly without grinding to a halt 1/4 of the turn, and there is no laboring on the straight way.

    So moral of the story.....binding ain't normal. Driving a vehicle in 4HI all the time ain't necessarily good for it either.
  • Did you ever identify the problem with the clicking in the dashboard. My dealer says it can be fixed for about $700. Dashobard has to come out to fix. Can GM be responsible??? I sure hope so.
  • After a heavy rain yesterday, I found water drops on the rear seat, driver's side. Looked up: water stain (still dripey) on the inside roof liner. It's about 6 inches over from the middle of the window; approx 6 inches in diameter. There has been no prior problem (known). The car has a sunroof. A leak issue makes me sick to think about. I also have the "pleasure" of having the "surge/clunk" issue -- there is no fix from GM.
    Not looking forward to going to the dealer, particularly unarmed. Anyone experience this (actually, I hope not); would appreciate any suggestions.
  • raleighraleigh Posts: 98
    Sun roof leaks are a common problem, inherent any time you cut a hole in the roof. Most often, the problem is either your drain holes are plugged (try blowing them out with compressed air), or the roof was not completely closed.
  • fife2001fife2001 Posts: 1
    I just took my Envoy to the dealer and they said this is totally a lie. Could you please send me the jpeg file to
  • Thanks for the info.
    The roof was completely closed, so I'll check the drains. Where are they? :)
  • Dear Sir:

    I'm in Beijing China. I found the blazer this Sunday & decided to buy it. But I found the news today that the blazer is not safety & ranked the highest death rate in U.S.

    I know the 2002 design (trailblazer) is much safety than 1996 ones(blazer). I don't know if the blazer here is 2002 trailblazer or 1996 blazer, I could not get answer here in China.
    I've some photos here.

    Could you help me? My email adr is :

  • tidestertidester Posts: 10,059
    Check the 10th digit of the vehicle identification number (VIN). If it is "T" then the model year is 1996. If it is "Z" then the model year is 2002.

    tidester, host

    I had to bring my TB in for a second time for a squealing sound coming from the right front wheel area. This time they had to replace the axle seal. This also cost $100 on my GMPP deductible. When I left the dealer, the car died out while idling at a stop light. I re started it and drove to a Mitsubishi dealer who gave me a check for my TB and wrote a very nice lease on a 2005 Mitsubishi Endeavor Limited AWD. I guess there really was a straw that broke the camels back. I'll see you at the Mitsubishi Endeavor forum.
    Repairs made in 3 years:
    replace engine
    replace wiper motor
    replace instrument cluster
    replace both outside mirrors
    replace both brake light sockets
    add gasket to rear license plate area.
    replace 3 of 4 brake rotors due to rust
    engine cooling fan roaring
    mushy brake pedal
    gas smell upon cold startup
    sway bar links replaced because of clunking
    replaced ignition switch
    drivers side auto dimming rearview mirror stays dark
    all recalls done
    replace right front axle seal

    Enough is Enough

    Best of luck to you with the new ride. Have enjoyed having you on this forum over the years.

  • ross1962ross1962 Posts: 229
    As for the "better performance" I'm not so sure. I never noticed any better performance.

    It depends on the application - the air box, how much air it's getting, is the air cold, or warm. But yeah, on these vehicles, most have noticed an increase.
  • ficussficuss Posts: 541
    hardhawk and others, come on over to the other forum to see what others have to say about their rides. The past 3.5 years have been very interesting here. I never felt it was about the people. It was always about the triplets. But I finally reached the end of my patience with this car, and it was time to either fish or cut bait. I hope the Endeavor is nothing like the Trailblazer if you know what I mean.

  • ross1962ross1962 Posts: 229
    Highest death rate? No. And at any rate, it has to be better than whatever they're making in China!
