I have a vibration when Im on the gas over 30, Motor purrs and trans shift nicely, fluids red not burnt. Getting a set of rims saturday. But I dont think thats it. This is a small vibration it doesnt get any worse as speed increases. And if I let off it coasts smooth as glass. wheel bearings are new as are motor mounts. A broken mount maybe?? Help please
x3 bad u joints with slack in them or "hard spots" will cause vibration when accelerating/maintaining speed. They will usually smooth out when off the gas or in neutral. To check them is easy. Put the car in N and see if you can turn the driveshaft and the yoke (also the pinion flange at the back) in opposite directions, if there is slack you have found the culprit. Hope this helps!
