I have a 1992 Dodge Caravan 3.3 AT. I have a knock in the right front it is a light knock when you are driving straight and as you turn left it gets louder. You hear nothing when you turn right. You can not feel anything thru the steering wheel also this has been going on for 4 years and 20000 miles but now I want to sell the van so I have to fix this. Also I did put a new rotor on last year. CV?? Wheel Bearing???

 

Sounds like the front stabilizer mount in the frame. A worn out bushing can cause this.
