I have a 2004 Chevy TrailBlazer 4WD and there seems to be a new noise coming from just below the shifter {outside noise}. It sounds like something is winding up when you accelerate and stays at certain sound levels at certain rpms but reduces as you reduce speed. It does not make this noise while at idle or when in park , even if you rev it a bit. Just curious to see if it may be low fluid levels in the front differental or transfer case. Your imput would be appreciated

I went to the dealer to check on the price for the idle pulley and they said that was waht the problem was. The quote from them was $99 for Labor and $38 for the pulley..Solution $18.00 at the parts store and 20 min from my hubby and it is fixed. The only problem with the pulley form the auto parts is that the original washer won't fit in the hole so we had to but a seperate washer. Runs great now I just have to find a solution to the gas gauge and fuel sensor.

SOURCE: fluid leaking onto the front passenger side floorboards.

2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.

SOURCE: what type/brand of transfer case fluid is recommended & quantity

Auto tek fluid, it's blue, you get at your dealer only. If you don't spill a drop you will only need 2 qrts. if you spill just a little then it won't be full and you'll end up needing 2.03 qrts.

Sounds like you got it. They are heavy and ocward (spelling?). As for the front drive shaft take the bolts out and give it a couple of wacks with a dead blow hammer then slide it out. Maybe a few days before hand give it a good spray down with wd40 or like product. Also when you get to the last bolt for the t-case to trans loosen it half way then put a drain bucket under it and seperate it a little and let the trans fluid drain some, or you will be wearing it.
