Hello,
 
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.

1st noise) a whining growl (or growling whine) on acceleration...not always, and seldom above about 35. Torque converter? 2nd noise) possibly related to ist noise? the vehicle "shakes" starting at about 62 mpoh. does NOT shake the steering wheel. have checked u-joints/axle bearings, and they are fine. it does not shake, shimmy, or anything else below 60 mph.
related? separate? help???

It is probably the tires and alignment. However, that may be a job for the $90 diagnostic fee. If you pay the diagnostic fee and they work on it and it does not fix the problem, they must continued to work on the problem until it is fixed. At least that is the way it is supposed to work.
S10 vehicle problems are really difficult to diagnose so before they offer to diagnose and fix the problem, they may tell you: "Take it somewhere else".
 
That actually happened to me when I had ABS brake problems. The ABS modulator is not serviceable and a rebuilt unit costs $800, if you can find one. The repair shop service manager looked me up and down and made the determination that I could not afford a $1000 repair bill on a 1991 S10 Blazer that is not worth $2000 on the open market. So I received the "Take it somewhere else" routine or what people used to call "The bum's rush"
 
 I later determined that we do not need the ABS system and your brakes will work just fine without ABS. The difficult part is bleeding the system with ABS. Bleeding the brakes system along with the ABS modulator is an all day job for two people if you don't have a $400 GM Tech 1 Scan Tool to cycle the ABS as you purge the air out of the modulator. If you don't get all the air out of the ABS modulator, yoiu will have soft brakes or no brakes at all. We managed to get the air out of the ABS modulator but it took all day. I will never know the ABS brakes do not work until I jump on the brakes on icey or wet roads. The ABS on my 1994 Ford F150 pick up has not worked in about 12 years. It is not a requirement that the vehicle has a working ABS system in order to pass state safety and emissions inspection.
 
The GM Tech 1 scan tools have been unavailable for several years and finding a good used on one for $400 e-bay is a crap shoot. .

#189 of 192 Blazer rear tires locked up and put me in a skid while driving by amyalderman

Can anyone tell me what would cause my rear tires to lock up and put me in a skid while driving down the highway? I suspect its the drive train but I'm being told it could possibly be the brakes.. I am a single mother and don't really know much about this, all I know is that I was scared to death and I don't want to get back into the truck until I know for sure it's fixed... and don't want to get ripped off ( like I allllllways do) at the repair shop. I need help! Thanks
