So the mount was re-done in a proper way today.
The suspension arm now fits in without any issues and the bolt that holds it is also in a straight line.
After the finishing was done my denter fitted back all the stuff and asked me to take a test drive.
I did, and took the car to rough roads, over some 7~8 speed bumps slowly, and with speed on some.
I was happy that there was no creaking or squeaking noise.
I returned to him and gave him the okay signal.
Every thing was removed again and the base was prepared for paint.
Now after painting it, the fitting was done and now once again I can hear squeaking sound, (its very less now) whenever I cross a speed bump.
It squeaks from the right side when the car is climbing the bump, no sound is heard when it comes down from the bump or hits any pot hole etc.
Plus the alignment was disturbed after this so I got that done aswell.
Here are the pictures.
The first one is of the widened hole.
The second one is after the paint was done.
Then are the final pictures.
