Carden Block Joint

[stuartu]

Before draining the axle check that the offside rear hub is tight on the halfshaft.

Absolutely, Robert. Furthermore I would check that the pinion drive flange is tight on the pinion shaft, which will involve removing the carden block housing, not too daunting and this is going to happen anyway when you fit David's propshaft.Try the hub first. These both relate to the delay in take up.
I would be reasonably sure that the noise on left hand bends is not likely to call for a back axle rebuild but, somewhere along the line, bits of propshaft assy. are touching something - could be either end.

Regards,

Stuart
