the bolt which is shown in the pic is loosen and the threads of the chassis are gone. Because of this, it makes noise. It is the right side, where right lower arm connects. I went Pune to meet the mechanic who did remove the bolt & tried new, but they were also in vain. All he told me to do tapping below where the threads of the chassis are gone & to use a rough threaded bolt.
another gas welder told me that he can make a hole & place the nut & will weld it & then we can fit the bolt inside. however I have a trust issue there. Any suggestion?
