So I have a 96’ 4d 4x4 blazer. The other day going to work I started hearing the low kind of roar/grown coming from I think the front passenger side wheel well area. I can hear it all the way up to about 40 mph and I can feel it vibrating even when I’m going in really low speeds. I replaced the bearing thinking that was my problems because I knew they were starting to go bad. After I was done the noise was still there. I don’t hear the noise as much in reverse and when I go into 4 wheel drive It make a really loud clunking sound. I don’t know much about 4x4 assembly and not sure where to start. I was thinking maybe the CV? Anyone got ideas?

 

Sounds like a CV to me, but I'm not experienced with them so I'm not 100% sure on that.

Any Idea how big of a job it is to check/fix? or is this something that is better left to a shop to look at and fix? My tools and knowledge are kind limited.
