Ok, it's getting worse.. I put in a new CV half shaft about 2 months ago,
and now anytime I am accelerating, the whole front end vibrates. BEFORE
I put it in, all I heard was clicking... no vibrations..

Now, I read that straightline vibration is not caused by a bad outer joint, but a
bad inner joint. If this is the case, is it the inner CV joint of the half shaft?

Could it be the rod/bearing which goes to the transmission box?

I've lost around 40 miles per tank in the last few tanks of gas I got, and I'm
wondering what's causing it!

 

sorry i'm can't help but, if you hear clicking like on acceleration and decleration in a straight line (usually single individual clicks, but not in sucession) which part of the axles would be bad? just trying to figure out what's wrong with mine why it clicks like that so much

 

My old Integra had a bad CV joint that made the entire front end shake when I accelerated. Jack the car up and see if you can shake the CV joint with your hand. I could shake mine by hand. Mine was caused by hitting a pot hole also on the interstate when they were doing construction.

 

You axle is bad (the three joints in the axle located on the opposite side where it connects to the hub is bad).
