There is a squeak when I accelerate and goes fast as I press pedal. Once I take foot off the gas pedal the squeaking slowly stops . Blazer rolls good . Funny thing is there is NO squeaking when going in reverse .
I replaced the brakes rotors calipers
Drive shaft ? Unjoints ?
Thanks in advance

 

Is it a brake squeak, from worn brake pads?

If it's not a brake sound, then the first place I'd check is the u-joints on the driveshaft. Your symptoms sound like a worn u-joint to me.

 

It was the unjoints
had both drive shaft unjoints replaced
blazer sat for 2 years
Problem solved
Thanks

 

Nice call.

Thanks for letting us know the results. It's always good to close the loop like that.
Thanks George! I don't know nearly as much as you do about cars, but it is fun to be able to help and to get one right now and then.

 

It’s very satisfying when you help somebody figure it out
