I have a 2007 trailblazer (saab 9-7x) 4.2L.
I replaced my CV shaft assembly thinking it would fix slight vibrations (felt at steering wheel) and clicking noise when turning. I also changed the diff fluid at the same time which took up about 1 quart.
after driving a couple of days I noticed a whining noise start to progress and vibrations got worse, getting worse by the day. as if the wheel bearing was going bad.
I went to inspect the wheel today and when I spin the wheel forward there is a constant loud clicking noise.
Spinning the wheel in reverse the noise is minimal.
When spinning the wheel forward there is at some point in the turn resistance, as if a bearing/gear was bad.
I can feel vibrations at the CV shaft assembly where it meets the diff.
whether it's the diff I'm not sure. checked diff fluid is fine and topped off.
I found a video that closely resembles the symptom:

I'm thinking there is a chance it could be the new CV shaft assembly and I still have the old one to test.
or it's indeed a problem with the diff, what could it be?
(just to mention; the old C-clip on the CV shaft I took out didn't fall in or anything like that)
thanks for any feedback
