gimbal bearing or universal joint failure?
Is there any way to tell the difference between gimbal bearing or universal
joint failure. At the end of last season my boat (1984 bayliner,305, volvo 280) started to vibrate when I made turns hard to port or starboard or even when in the slip at low rpm it still had the vibrations when I turned the wheel hard one way or the other.At top speed going straight it was smooth as silk.I appreciate any help you can give. Thanks, Dugb |

The best way is to pull the outdrive and check them by hand. It is not
unusual for there to be some vibration on a hard turn, particularly if the drive is trimmed up or down some at the same time. "doug" wrote in message ...

If it is ok going straight, likely its the u-joints.
Checking it with the drive removed, hold the end of the spline (spline in palm, thumb pointing to u-joints) and give it a twist to load the bearings tight, then, exercise the bearings by drawing a circle. If it feels smooth, you're ok, chances are you'll feel the roughness - feels like rollers riding over small ridges, a sort of sliding over a washboard effect. If you do a 90 movement one way then the next 90 degree direction, you won't feel anything. Tan PS "doug" wrote in message ...
