Forgive my ignorance does this advisory have anything to do with the costly geo bolts?

thanks

Nearside Front Lower Suspension arm rubber bush deteriorated but not resulting in excessive movement

 

It's hard to be sure which bushing they are referring to. From memory there are 3 on the lower control arm and 2 of them are 'geo bolt' bushings. I believe most people experience the caster bushing going first so is likely related to the geo bolts however they are only costly if they are seized...

 

As above would be the Compliance bush cracking <Caster>
