Re: "Krrr- Krr" sound in lower RPMs the KRRR KRRR sound which you are referring to at low rpms in high gears ( this you will observe if u drop the rpms to 1000-1200 on say 3rd gear/2nd) is from the drive shafts. there is no problem in the vehicle or the drive shaft. the drive shafts have ball joints in the end and they are designed to have a play so that they dont suddenly fail due to fatigue failure. it causes Krrr krrrr sound just for a while, a very minor ones. its kind of resonating sound. i can reproduce this in my alto, indica and even my brand new linea.
