transfer case chain

How do you know when the transfer case chain has stretched? I have a 97 TJ and have recently started hearing a clanking noise from that area. If this is the chain would removing front drive shaft take some load off of it until I can get replaced?

It is my understanding that the transfer case chain is only under load when 4WD is engaged so removing the front drive shaft won't help.

While not under load, it is still being turned, so yes, pulling the shaft would help. How much, not very much.

How does this one look?



Ive gotten some clunking when accelerating in 4WD both Hi and Low. I tore my transfer case apart yesterday to check things out.

I found a small spring that looked similar to those used in the A/C system to hold hoses together except it was broken into a few pieces inside the rear output shaft housing.

I also found some side to side play of the input gear inside the planetary gear setup. I can't find anything in the FSM about play in this setup.

Otherwise everything looks good. Even the plastic pads on the selector forks look brand new.
