Hey Cuda, dodger is right the wheel bearing and hub assembly is flawed but my 79 threw all the roller bearings out onto the hiway the wheel was out almost horizontal but still attatched and rolling. I think it is possible to change the whole axle with one of the parttime units. I believe Robo can give you some good info on that one. Do you own a Cuda? I have a 69 convertible Cuda with 318. It's a whole lot smoother than the R/Cs . Happy trails Joe
