Hey guys, I have a 2000 2door 4x4 blazer. Yesterday my truck started making a grinding noise at any speed and the rpms would fluctuate freely and it shifted pretty hard. It also has the grinding off and on when it's in park. Any ideas? Thanks

 

Yes. This is your third thread and it's getting worse. Making noise sometimes at idle, then its constantly noisy at idle, now the noise is consistent at any speed. Please give us some details to work with.
