My RRS has just got its first MoT with no advisories! I've been worrying all day!

well done, shows you have been looking after her.

My car went through MOT every year without advisories until the last one when it highlighted rear track control inner bushes. It had 27 ball joints fitted in the first two years of its life, then never required another or wishbone bushes which seems to buck the trend. 2x TDV6. SE and HSE. Both returned to sender with issues👀
TDV8 Sport HSE...... Gone. Loved it but it didn't love me!!
Now rolling in MY10 Fullfat TDV8 Vogue. Slammed it to go round corners🙈

27 balljoints in 2 years?

Yep, 27, plus numerous drop links all in an attempt to solve the clonk in 2007 cars, at one point, the ball joints were not available when LR realised they had a design/manufacturing issue and started using TKN instead of Fisher-Price...... Also had body to chassis struts removed and eventually as we know, anti roll bar and bushes replaced which took two years to happen and finally resolved the "operational noise" we all know about.  2x TDV6. SE and HSE. Both returned to sender with issues👀

The whole ARB bush issue should have been a huge embarrassment for Land Rover.

Release a whole TSB on what to check, and what to replace without even mentioning the ARB's

That said, I do remember almost every D3 + RRS coming in for new ball joints at their 1st service
