    I recently bought a used 2005 trailblazer and when in 4 wheel drive and reversing with the wheels turned more than half way, there is a loud thunking sounds (I don't know how else to say it).
  2. No reverse or 1st & 2nd

    First let me ask the question, Is there any other reason for no reverse other than a broken sunshell gear? History: 04 envoy 170k miles rebuilt motor unknown miles since rebuild. Tranny went out this fall (drive band) bought a used lower mileage trans at a reasonable price. put it in and in true...
  3. No Reverse, then reverse, then no issues

    Hi All, I have a 2002 Envoy with 226,000 miles, I am the second owner. Got in my truck Saturday and put the vehicle in reverse, did not go. After a few minutes of trying, revved up the engine and it slammed into reverse. Drove about a mile with it making noise (sounded like marbles) then back...
  4. Reverse Light Socket - where to buy?

    2005 Envoy SLT. My driver's side reverse light went out. I went to put a new bulb in and when I removed the old bulb I noticed a ton of rust/corrosion in the socket. Its beyond repair. The socket is toast. I looked a bit online this morning but was unable to find an aftermarket replacement...
  5. out of

    I'll be as to the point as possible: Sound coming from passenger side. When hitting bumps. Loud clanking at General speeds (15-50). Under certain circumstances the clanking can turn into a grinding. Also noted a card in the bike spokes noise upon reversal only from time to time. I've replaced...

  7. 2005 Envoy XL Reverse Light Issue

  9. HELP!!! Reverse Light Wiring?

    Hey everyone, I have a semi-major issue. This evening, I hooked up two reverse facing fog lights, powered by the 12v power source in the rear of my TB from the cigarette lighter receptacle. This worked great because I had it powered through a fuse, which connected to an on/off switch provided...
  10. 4WD very difficult to go in reverse, jumpy & loud

    4x4 Drivetrain
    I just took my car to get it's oil changed. I live in Seattle, lots of hills and it's snowy today, so I put it in 4WD for the first time in months, even close to a year maybe. I found myself attempting to back up in the parking lot (before the oil change), and the car was very hesitant to go...

  13. Reverse Lights

    I noticed that I was collecting water inside my reverse lights (both sides), has anybody else have the same issue. I did remove them, drained the water and let’s see what happens. I am not sure if it is the "rubber gasket" or a serious case of condensation.
  14. Grinding sound when backing up

    Ok, I noticed this yesterday after washing my brakes out from the last offroading trip, plenty of mud in them. But anyways its coming from the front end, but only when I back up my driveway. My driveway is on a slight hill, nothing major. I can feel the vibrations through the steering wheel...
