Thanks Nick
I gave him a call and he said that amount of end play is not good, but there could be other issues.
What else under there, makes a dull rattle and sounds like something hitting the body, but only over bumps ?
The car seems to drive fine, no bearing noises, just this annoying rattle :grr:

72vet:
Have you looked at the front Diff mount?

It's old, but still looks pretty thick and tight.
I broke one on a 68 years ago and it made a hell of a noise as soon as you let the clutch out, almost like the ring gear lost a tooth.

This is more of a dull rattle, only over bumps and sounds like something's loose ?
I think it's possibly the side yoke retaining clip (or clips) I can pull the yoke out of the diff 1/2" :banner:
I believe the little clip at the end of the spline is all that holds them in ?


sirfixalot:
Maybee exhaust where it comes under diff my 78 has a sheet metal heatshield there which I have never got round to fitting after replacing diff.
Handbrake cable on exhaust pipe?
