Jumping in reverse

[Malcolm Parker]

I think your problem is common to many Austin 7 specials and does not imply that there is anything wrong with the rear axle.  Check that the torque tube mounting has no undue play and the rear shock absorbers might benefit from adjustment.  If you are at a gathering of Austin 7's and it involves reversing up a grassy slope you will see all sorts of  jumping about by the rear axles.
