P38 transfer case front output bearing

Hi all,
Car is a 97 4.6 HSE automatic.
I was under the car to replace the radius arm bushings. I have been wondering if I have a worn bearing somewhere in the driveline, because there is a slight vibration that I can feel through the soles of my feet and I don't think it's always been like this.
So I checked for play at both ends of the front prop, and there is indeed a tiny amount of radial play at the front output end of the transfer case. Is this normal? I have seen a write-up on here by Busterbus of this bearing being replaced, but I don't know if I have the same box. His had a single ball bearing in this position and I'm thinking that this may indeed have some play, even with a new bearing in it. Am I right, or should I pull the bearing?
Does anyone know what the correct bearing and seal would be? Landrover part numbers or industry standard.

Cheers!
Henrik

You would have to remove the viscous coupling housing to replace the bearing. Should be an industry standard bearing. First check the flange is not loose they have been known to back off. Suggest you read the numbers and get a bearing from another supplier Land rover price is astonishing. http://www.rimmerbros.co.uk/Item--i-RTC6025
