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

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
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!

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?
