When got on a street that the snow plow had removed most of the snow and I maded a u-turn thats when i first noticed the bogging down. Then I went to a paved parking lot and did a few turns and it continued. It only happens in 4hi. Replies to this message: burdawg (Dec 21, 2007 6:36 am)

Replying to: treburt (Dec 20, 2007 9:06 am) That's normal when you have good traction. In 4 wheel drive on dirt, mud, snow, ice, etc. since the inner wheels don't have as far to go as the outer wheels, they slip a little in turns. With good traction they can't and it feels like it's "bogging down" as you say. It's best to try to avoid it when possible.

Replying to: treburt (Dec 20, 2007 8:08 am) Totally normal. If traction is that good, shift it back into 2High . Replies to this message: treburt (Oct 27, 2008 2:40 am)

I have a 2005 Trailblazer that is making a very annoying high pitched whinning sound. At 1st we thought it may be the PS, but that is fine. We then narrowed it down to the Alternator, but when we replaced it there was no change. We can not pin point exactly where the noise is coming from, but it is getting louder and worse by the day. My thought is possibly the Water Pump, but there are no signs of leaking, overheating, etc. Has anyone else had this problem? No one can seem to pin point the problem. Help!!!!

Replying to: frichards62 (Oct 28, 2008 7:37 am) it could be the serpentine belt idler pully. have that checked.
#9 of 11 2005 Chevy Trailblazer losing power.. by davedoran1975 Sep 25, 2009 (4:50 am)
Driving in the first few gears, it seems the engine seems fine. In the last gear though, when speeds are over 45 miles per hour, it seems as though the truck is just dying. I can be at the same speed of 50 MPH, but I watch as the RPM gauge starts to drop. It does this a lot especially if there is stress on the vehicle (i.e up hills)   Sometimes when driving at that high speed and start to go up a small incline, the engine will start to slow down and the rpm's will bounce up and down like it's losing power   I had a tune up and they replaced the spark plugs, i had a engine flush, etc.   What else could it be?

Replying to: frichards62 (Oct 28, 2008 7:37 am) recently had the same issue... LOUD whining noise. Took it to my local mechanic, he replaced the idler pulley - eliminated the problem entirely. ($135 repair). Good Luck!
