  1. Vibration from 68--78 mph.

    OEM Issues
    Just solved my vibration problem...again. 2003 Trailblazer 4.2, 4WD. NOT extended version. Currently 247K miles. Several years ago, I had a vibration and noise from 68--78 mph. No* shake at 65 or at 80 mph. Worst about 74 mph. Not dependent on power or trans gear--would do it on throttle...
  2. Rough Idle(Not Throttlebody)

    OEM Issues
    Ok, so I just got a 2005 Envoy 4.2L wth 140,000 miles on it. It had a rough idle so I cleaned the throttle body and it helped a bit. This morning the check meter light came on and i noticed that my oil pressure was going from half to a quarter back and forth. It was running pretty darn rough...

    Before I start, thanks for taking the time to read this post! I've been experiencing a problem of steady low groan(low speed)/rumble(mid-high speed) and vibration that increases with pitch and frequency and don't know the culprit. The noise and vibration is consistent at a set speed whether...

    OEM Issues
    I hope this is in the right thread! I have a 2005 TB 6 cyl, 218,000 miles. Always well maintained. Runs fine, shifts fine but there's a noise when driving. It's not there at low speeds but the faster the rpm's go the more noise I hear. It's coming front the front. Not loud, nobody turns to see...
  5. Loud Noise + Shudder

    Hey All, First post ever! I posted in this section because I have no idea what it's concerning/where it's located and what's wrong. Several weeks ago, I noticed this shudder/vibration under the steering wheel whenever I first started the car or right after I shut it off (the engine normally...
  6. [SOLVED] 2002 Trailblazer EXT Vibrating Hood

    The "How-To" and DIY Section
    I have a 02 Trailblazer EXT that when in idle or sometimes accelerating the middle of the hood vibrates. I'm thinking a brace or bracket of some sort would stop it from vibrating but I have no clue if a brace would work or even how to remedy the problem. Any help is appreciated.
  7. Front End Vibration?

    OEM Issues
    Hello, I have a 04 trailblazer with 130,000 miles on it. Last week I replaced my radiator and water pump and added a transmission cooler, because it has been running hot (over 210) it’s been doing this for the past 3 summers and I have previously replaced the thermostat and fan clutch and it’s...

    2005 Chevy TB LT I6 4x4. I had a vibration in my steering wheel for a month or two, which was more noticeable on the highway at speeds of 65+. As it progressively got worse I finally took it in to get looked at. The shop said I needed new ball joints on both sides of my front end. I replaced...

    4x4 Drivetrain

  12. Front end vibration/rattle at speed.

    General
    I have a 04 TB EXT 4x4 that has developed a 'rattle' above 45 MPH. It is more of a vibration in the floorboard than a noise and is only noticeable on a smooth road. The best description I can give is it feels like someone is hitting the floorboard with a rubber mallet intermittently. The...

    My trailblazer developed a vibration in the front end recently, along with a swoosh-swoosh sound most noticeable around left turns.

    I Have replaced all four rotors and pads on my 04' 4x4 trailblazer @90k mi, in an attempt to eliminate a vibration that only occurs under braking. The vibration is exactly what I have experienced in other vehicles with warped rotors, however after replacing them the problem persists, under...
