I noticed my 1999 Blazer makes a Wooshing sound on front passenger side when driving. Looked and saw grease build up on brake line and lower ball joint. ball joints are new. Looks like it is leaking out of the CV boot but could not find any tears etc..

Should I just repack the CV boot? I was concerned it could be the wheel hub as well. There are no clicking sounds when turning.

 

Sounds like the boot is leaking. They are fairly easy to replace. first you need to find out if its the cv boot (outer) or the tripot boot (inner)
