Midget - severe vibration from rear under hard acceleration.

[minimoog]

Hi - I have an Healey Frogeye aka IOW Frogeye built on a '64 midget drivetrain. It has a Ford Type 9 5 speed box. Under hard acceleration in 1st (which is too low a ratio for the car really, but there it is), and sometimes in 2nd, I get an alarming severe vibration or juddering from the back axle area. This has gradually got worse. At first when it wasn't as bad I thought it might be a bit of clutch slip, and I suppose ti still might be even though the clutch (a Peter May item) hasn't many miles on it, but as it has got worse it definitely seems to be from the rear. Under gentle acceleration and in higher gears there's no problem.

Anybody had anything like this before, and what was the problem? It'll be in for MOT soon so I'll have it looked at then, but just angling for any pointers in the meantime. Cheers.

Hi
It could be the rear U/J joint that is worn out?
