I have rear-axle air "Sports" suspension. I like "sports". Don't want it any stiffer though.

I'm getting more and more noise from my front struts. Anyone have luck lubricating the mounts/top bearing or should I just replace it all (strut and top bearing)? Seems like it is still on its original struts at 153k. Can't complain about that.

About replacing - BMW originals are about $300 per.
Bilstein HD are like $230 each. Anything else that might match the quality and feel?

Thanks!
