The other day I was reversing out of my garage and I heard/felt this quite loud vibration in the front left wheel area and it shakes the whole front end, then while I was driving I started to decelerate without braking and it vibrated just as bad as when it was in reverse. I just replaced my driver side axle and the problem still persists. Im not sure if its the wheelbearing, lower ball joint or clutch/throwout bearing?

 

jack it up & check for all bushing & ball joints. might be your driveshaft inner cv joint gave way too.

 

Deffinatly sounds like the intermediat shaft (if thats what you implying)
Also check for any wiggle room between your axle and the shaft.
i have that prob, just no time ti fix it...

 

correct

 

Would the intermediat shaft being warn out affect you steering at all? i wouldnt think so, other than the vib.

 

well i just replaced the cv joint.. I mean I know there is a possiblity that the new one is bad. Also it happens when im not even in gear say if i hit a big enough bump it'll vibrate and it sounds like a thumpthumpthumpthump + vibration. I've had this problem before I just cant remember what it was or how I fixed it, probably 3+ years back

 

Yup. Thats the intermediate shaft. i can almost garentee it... almost.
Its easy to check tho. just get under there a play with the axle. if it wiggles, fix it.
