Hi my car 2007 Nissan visia 1600 petrol manual transmission, my garage m.o.t. Replaced suspension lower arm with ball joint attached . Was it not possible to replace ball joint only when they said ball joint had excess play ? , did not have any obvious symptoms when driving . Thank you

My car has a manual transmission.
Hello. The ball joint is available separately, and as part of the control arm assembly as you note. Although it can be purchased separately, removing it and replacing it into the control arm requires heavy duty presses and tooling (great force required). And if the control arm is aluminum, it is a more risky process since the aluminum is softer than steel, and the remove/replace process may not result in the ball joint fitting as tightly in the control arm as would be safe. For the mechanic, sometimes the separate ball joint is not readily available, only the control arm with ball joint. And the labor time to press out the old, press in the new may result in a more expensive repair anyway because of the additional labor cost. It’s a toss up sometimes, especially with parts availability being a deciding factor.
