#175 of 192 1998 Chevy Blazer 4X4 rumbly drivetrain
Nov 04, 2009 (9:21 am)
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?

Perhaps a loose tail pipe?

Did you every figure out what the buzzing noise was? I have the same problem with my blazer and it is driving me crazy.

Just bought 02 Blazer. It had over heated. Mechanic replaced heads, sensors, etc. He said the pistons and walls looked good. I still have a loud tapping noise when accelerating, cold & warm. Less noise with higher rpm. Quiets while deceleration. Mechanic said there was Tech Service Report that said "Some Blazers had pistons installed backwards to try to increase compression. And this was causing the noise." Anyone heard of such a story? He said compression is good in all cylinders. Any other sources of the noise? Much appreciated.
