Diff oil leaking onto break shoes

The main reason I was looking at the wheels etc was that when returning home after the Wirral Classic Car club run on Sunday I started getting a significant vibration that felt like it was coming from the back end somewhere. Tonight, with the car up on axle stands I started it up and went through the gears. First, second and third were ok but as soon as selecting fourth the vibration starts.. now I’m confused.... 4th is straight through so is the vibration originating in the engine? Could it be the prop shaft? Why no vibration in other gears or in neutral and revving. Is it the gearbox?? Engine revs nicely under no load and does so in the first three gears so thinking it’s not that.. not that much play in the propshaft and would expect vibration in any gear if it was that.. gearbox was fine and I don’t hear any nasty noises from it.. wouldn’t I get symptoms from the axle in all gears so why only 4th???

Any ideas??

Only in 4th will the rotational speed of the tailshaft and wheels show up balance issues. Wear in the universal joints and splines will cause the prop shaft to be out of balance.  Have you lost a wheel weight?  cheers Russell
