I have a 2009 Versa hatchback/ 4 speed automatic transmission/ with around 165000 miles. It started making a whomp, whomp, whomp noise like a flat spot on the front tire, the tires needed replacement so I put 4 new tires on, no help. Changed front wheel bearings, no help, boot on left trans-axle bad so replaced trans-axle, no help, listened to transmission and differential and all bearings with mechanic's stethoscope, carrier bearing on right trans-axle making noise, changed trans-axle, no help. Noise louder when drifting at low speed. Also changed auto transmission fluid. Has anyone had similar experience of have any ideas on what is going on?
