clutch release bearing replacement

hey guys,

i was wondering if anyone happened to have a step by step for replacing a throwout bearing... it sounds lame, but i've never done one before and i was looking for pointers, tips, tricks, etc...

thanks!

ps - ive got the 2.2 with the NV1500 5 speed.

4W drive?

If the throwout bearing is bad it may need a new clutch and pressure plate and clutch slay cylinder.
How many miles on clutch?
What is the throwout bearing doing or not doing?
