I was not clear. Yes, there are certainly other areas you can add grease if you want. I imagine some owners do so even though they are sealed. Without doing any lubrication the life span of the suspension on an X5 is usually around 100,000 miles. My guess is if you use what is used on BMW ball joints that should be lubricated you will not have a problem. Due to the viscosity of CV joint grease I don't think it is a good idea to use it on other areas you would like to add grease.

The CV boots are a different story and that's the reason for the focus on them. it is not unusual for the boots to leak grease when the cv joints are still in great shape. Even then it is time to replace the boots and of course the grease rather than just add grease.
