shimmy in suspension
i have just restently built a 1979 elcamino and i put a whole new suspension and drive train in it. i built ladder bars and put coil over shocks on it. the problem is when im slowin down i can feel a bad vibration threw the steerin wheel and the floor. and i even put it into nutral and it still did it. i dont know where it could be comin from. i have a posi diff. in it also.
