Hi...thought I got a great deal on a new-to-me '87 Sammy, until the violent vibration and clunking began to occur...along with the constant whinning noise in all gears. Thought I (and a couple mechanically inclined Sammy owners) had narrowed the source down to tranny bearings. U joints were all in good shape. Well, after pulling tranny, having it rebuilt, replacing clutch and replacing all gear lube, the problem still exists. Anyone have any ideas?
