np 242 transfer case drive chain question
Does this chain move at all times or only in four wheel drive and my trnasfer case is making a weird clunking noise I jacked up the rear wheels andput it in neutral and when I moved the back wheels and then would move them the other direction it like makes a clunking sounds like something is loose and it in the transfer case could this be a loose chain. I don't see how it can if the chain doesn't move in two wheel drive bc then it wouldn't even be moving when I did the wheel thing thanks for any helpp I get

The chain moves with the front output all the time, but is only driven in 4x4. I just replaced mine(np242 chain) and with 222k it was so loose it was skipping on the front output in 4h. The chains wear out, it's very common. Hope that helps.

Yep!! To test this have a buddy come over to help ya Jack up the front wheels n turn both tires at the same time n u'll c that if the front tires r rollin the chains a turning!! If u have a full time locker up front then u wont need a buddy's help to c this!! I do believe the only way to stop the chain from turning is to install manual locking hubs!!

Ok so I guess the chain could be causing my clunking slash grinding sound while driving it happens when I let off the gas it clunks and then when I get back on the gas but I checked everything else that would cause it and the only thing that seems bad is the transfercase chain or something in there

I guess try n block the tires n disconnect both drive shafts n put the TC n gear n the tranny n neutral then turn both output shafts by hand against each other to find out how bad the chain is!
My motor tranny and TC are all out of my 89 limited....now in my 87 pioneer!! In my 89 I developed a clunk kinda like what ur describing but later found it was from the rearend!!!

OK well when my TC started making the clunking and grinding noise.... the chain ended up slipping off one day backing out of a parking space at Walmart and in turn split it wide open n spilling all the atf and demobilizing my Jeep!!!! I have been through 3 tc's now..... but one of em was due to my lead feet smashin on both the brakes and the gas running 33-12.50/15's with stock 3.55's (I snapped the main shaft inside the TC)!!!

I have a 242J transfer case. I just cracked it open and noticed the chain wasn't moving at all and it was making a grinding noise from behind the chain in 2wd? WHAT DOES THIS MEAN!?
