Subject: Identifying cause of play in Axle Half shaft
I have play or lift (up and down only) on my 1932 2 Litre offside half shaft (light axle)
The half shaft and bearing carrier was removed complete and a new good quality hub bearing fitted. The play was still present! The bearing is tight in the housing so both the normal causes are ruled out.
The next question is whether the splined hub is sufficiently tight on the half shaft taper and Woodruff key. I am sure it is but will check this in due course.
Assuming the hub to half shaft joint is not the cause, it points to the differential. Possibly wear in the splines in the sun wheel or the diff bearing both of which locate the haft shaft in the differential assembly. Wear of this type in the sun wheel splines would I guess be unlikely as the stresses in the splines are rotational? So it may be the diff bearing?
Before I get into stripping the differential out of the axle, does anyone have experience of such a problem or an opinion of how to accurately diagnose the cause prior to complete strip down?
Advice gratefully received
Regards
Mark
