Re: Chain slap NP231
The T case does have a certain amount of play, and I think what you
described is within spec because that's about what I have and I don't have
any rattling issues.
Now, you said it only happens in 4lo. You might look at your Tcase shifter
linkage, you might not be getting it all the way into 4lo and your linkage
could be needing an adjustment. Barring that, it might be your planetary
gear assembly. Once I pulled my T case into 4lo and got a strange "rattle,"
it sounded like gears clashing, but the T case wasn't all the way in 4lo. At
any rate, I don't think it's your chain.

Re: Chain slap NP231
It's never leaked that I know of. I'm going to change the fluids here in a
couple of weeks anyway. I'll see if it's low.
Also, I have a new... vibration.. that's all I can describe it as. When I'm
going down the road and have a load on the engine (i.e. normal driving) the
whole TJ buzzes. When I press in the clutch it stops, so I know it isn't
tires.
I just had that SYE/driveshaft installed, as well as having my tailpipe cut
at the downward bend just behind the axle (it was hitting my shock). Any
thoughts on what could be causing this?
Thanks,
Eric

Re: Chain slap NP231
I doubt that it's the chain. I have seen these chains get sloppy, and they
make one hell of a racket banging against the case, and it isn't only in
4LO. The ones that I have seen fail were due to prolonged operation with no
lubricant, and the bad chain was just the symptom.
I am with the other dude that discussed your linkage and the possibility
that you aren't fully engaged in 4LO.
