Play in prop shaft (diff end)

[phill 92]

Ahhh right I'm starting to understand this better now,

My problems are not necessarily due to the diff itself? My diff sounds very similar to the video although I don't think its at that volume yet! I also have a knock from the rear after engaging drive after gear changes every so often.

I'm tempted now to just continue to use my car as I do until the diff gets bad enough to the point where its un-drivable(diffs dont tend to die suddenly do they?), whilst saving a few £'s, send it away to a specialist and replace any parts they believe need changing.

My only problem with this is I hate not knowing anything about what I want to fixed as I could send it to someone to get told it needs this, this and this and get my trousers pulled down when I only needed something simple!
