Op 13

Tighten the 2 tie bar fixing nuts. Use the 14 mm spanner and the 9/16'' spanner.

The 2 nuts must be tightened to 23 mN. Unfortunately, since the space around the tie bar is very small, it is impossible to position a torque wrench. So just tighten it firmly.

The End

The front lower tie bar is refurbished. Well done! If the Mini continues to ''clunk'', you will have to do the same with the upper right tie bar.
