Clicky pod joints?

[Simon Wallwork]

I must be one of the last folk to use a D2 S8 as his daily transport- but it has been with me since 2009.

This 2000 model year FL car has started to make a clicking noise from the front- only when on lock and only under power.

I expect there is a problem with the front driveshafts, but can anyone give me a few tips about the problem, and how to fix it- or will it run like this for another decade? It's worse turning left. 148,000 miles now.

Many thanks!
