Replicating physics actor being used as a pawn

I have a vehicle pawn which is implemented as a physics object using the constraint system between rigid bodies. I need it to replicate in a multiplayer environment. I have it working in part. But the client sees very jerky motion. It’s almost seems that the physics is being run on both the server and client and the two are fighting with each other. (?) If I run game as a listen server, the server client works perfectly. So it’s the remote client that is having issues. Suggestions?
