FWD: 4000q problems

["PAT MARTIN" <MARDKINS@msn.com>]

This guy has a 4000q that is experiencing some problems.  I thought the 
groaning noise might be if he has not lubed the center U-joint  Does anyone 
have any ideas.  Reply to me and I will forward it to him.

About my Q - I think I have a bearing going in the center diff. This grinding 
noise has been coming and going for about a year or so now, but it has become 
pretty persistent as of late. Also, I have developed a cold running problem. 
About a minute after starting, the engine stumbles pretty bad at mid throttle. 
A complete tuneup, fuel filters, and new fuel pump did not solve the problem, 
so it must be in the injection.
