.... and you still need to ensure that all four bearings on each UJ
receive grease. Lever the spider across when greasing (don't damage the
seals) until grease shows at each seal in turn. Don't be too
enthusiastic as Martin cautions. The fact that you have had a single
bearing failure points to uneven grease distribution.
You'll find it easier to do this is the propshaft can be turned whilst
greasing the UJs.
