Vibration in Cabin

[datt_m]

Hi Guys

I have recently converted my ca20 auto u12 to manual. Problem is after this conversion, everytime i turn left there is a vibration which can be felt in the cabin. The vibration is similar to that of a unbalanced driveshaft at high speeds. It only does this when turning left.
I have used all manual parts including mountings stripped of a wrecking u12.

I am told it could be an issue with my c.v joints.
Appreciate any help.

Thanks.
