had that problem, replaced tensioner(which was shot anyway) along with a new belt. it appeared to me that the noise was coming from the clutch fan... never bothered with it and just put up with the squeak. had the blazer for another 30k and nothing got worse

just reading through and thought id add... a bad or loose u-joint will vibrate like hell and when stopped, going reverse drive reverse drive will give you a distinct CLINK if u-joint is bad

#173 of 192 O-2 sensor didn't work by jclime0001

My blazer has been having problems getting up hills (it bogs down) and I don't think it going to get me up the hills. It rattles and sounds like it is giving it all it has. In traffic the fastest I can go is 50 mph and that is with a hill giving me speed. It is vibrating now and stops vibrating only when I hit the gas and there is a smell that smells like something has burnt.
 
Since the O-2 sensors did not work in fixing this problem do you guys have any suggestions?

#174 of 192 Rubbing noise coming from rear end at low speeds by dart09

Oct 26, 2009 (5:10 pm)

I have a '99 Blazer LS 4X4 -- 159,000 miles (I know, woe is me). lol. Anyways, I have a rubbing noise that starts when the vehicle moves and seems to go away for the most part as I get up to highway speeds. It is more noticeable at low speeds. At first it sounded like it was coming from the right rear. I put it up on jack stands and the noise then seemed to be coming from inside the differential. I checked the pinion by hand for play and there is none. I then took the dif cover off and discovered someone had drilled a hole near the top center of it apparently so they could add fluid there? It had a black plastic plug in it. Yikes! Who worked on this thing before I bought it? Curly or Moe?
  
I've put in new front hub bearings, new u-joints on the rear drive shaft, new rear wheel bearings and seals and new rear brake calipers and disc pads -- the back plates are rusted away making the rotors visible on both back wheels. Will it hurt to leave the rusted away backplates as is? I also installed a new rotor on the right rear and had the other three rotors turned. There are no broken belts in the tires. When I changed the rear wheel bearings I didn't see any metal shavings from the spiders or from the pinion gear. There were no broken teeth on any of the gears. I also noted at the time that there were two shims on each of the spider gears. Does that sound right? It is a GU6 / 3.42 rear.
 
I am at a loss as to what is causing the rubbing noise and would greatly appreciate any help I can get on this. Thanks in advance!

#175 of 192 1998 Chevy Blazer 4X4 rumbly drivetrain by ripley09

I have a 1998 Chevy Blazer 4X4 and when i hit 45-55 mph i get a horrible growl/rumble (sound and feels like you hit the caution rumble strip on the road) from somewhere in the drivetrain. i have replaced the rear end barrings, took out the front drive shaft, replace the 4x4 drive vacuum pod. The problem didn't start till i put the new tire on it (goodyear ranglers). The issue only last for 3-4 second but it reacurres ever 30 second or so. If you speed up or slow down the sound/feeling goes away. If anyone has had or know what may be wrong with it I would greatly appreciate some advice because i am totally stumped. i have look over everything i can think of.

I hate to tell you this but it is probably your tires causing this noise. I had a similar experience when I purchased new Goodyear Wranglers. I learned that there are many different tire designs all under the Wrangler name. The tire store had put on an All-Terrain design on. Anyhow, I didn't even make it home on these new tires as the noise was so objectionable.
 
I had the tire store pull the Wranglers off and put Toyo tires on instead and they ride nice and quiet. Hope this helps.

I have the same problem, except the growling sound is coming from the front end. When I engage the 4WD, the sound goes away. Any luck figuring it out?

Have knocking noise coming from rear end at startup. Only lasts seconds. Then may not hear it for a while. What could this be?
