excessive?? play on driveshaft.

If its a landcruiser it is a very expensive job and is the 1st sign that there maybe other work inside that needs doing.The bearings themseves are only 20-30 bucks but once worn,damage the other componets and cost $2000-3000 for a gear set and labour..As you didnt mention the make of vehicle perhaps it is not so critical on other types. Get a 2nd opinion.

Gompy,
I'll second the first reply, get a second opinion, this sort of play is not normal unless it's a Lego toy or something like that, as long as you haven't got the decimal places wrong with the measurements you've posted you would normally think around the 0.05mm not 5mm, that's 0.002 thou, if it's an anti friction bearing you will be looking at tight clearnces if it's a sleeve and bush you could be up around the six to eight thou max I would of thought. I prefer the thou measurements I'm an older type mechanical person and can relate to thou's easier...... Keep the shiny side up

Thank you Ross and Martyn,
My car is a 1999 Pajero with 95K on the clock. I have done a fair bit of off-road driving.
I was told by the mechanic that it needs some of play in the sleeve, but to me it looks a bit much, then again it is not leaking, anyway I better get a second and maybe a third opinion.
