I have found the F48 to be extremely sensitive to suspension changes and generates loud banging noises when suspension components are worn.

I had a loud noise in the front, disassembled the suspension, and replaced identified worn parts. The noise persisted. I ended up replacing front suspension parts one by one until they were all new.

My point is this: a typical suspension inspection (moving the suspension around looking for incorrect movement) and even inspecting disassembled parts did not reveal any parts that should be replaced. But they needed to be replaced. The tolerances on this vehicle are unusually small.

I suggest replacing suspension parts based on mileage not by inspection.

By the way, I have not found the same for engine/transaxle/differential mounts which seem to be extremely forgiving.
