Ok. I just thought of this as well, I posted earlier that after I put fluid in it it feels clunkier and makes noise. This happens while in park as well. I don't know **** about T cases, but if it is in park and still makes the noise and is rattling, could it not be the T case? Even in park, the think clunks and makes a little noise, not sure if it could be anything else.

 

if it's making a noise in park look at the exhaust pipe that travels over the cross member. That pipe has a tendency to hit the cross member and rattle and bang around. If it is hitting, place a jack under the cat and jack it up till the pipe is not touching the cross member. Then take for a spin and see what other sounds there might be.

 

Ok, cool. I was thinking that it wouldn't be the t case if it was in park, but once again, i know nothing so I just wanted to get some confirmations.

 

The t-case shouldnt make any noise with the vehicle in park (nothing is spinning unless the transmission is spinning the output shaft).

I honestly would get an assessment from a good local shop and go from there, it really doesn't sound like a failed transfer case to me



Here are some t-case options. A used one should go for $75-$100 or so

EDIT:
Also, the 231 and 242 transfer cases are really not picky on lubrication. ATF +4, Dex III, 10w40 - all of them should "sound" the same in there.

If you don't have enough cash to buy the t-case locally, one option is to buy it on eBay or from a used/recycled parts distributor and use a credit card to finance the purchase.

 

Yeah I thought the T Case didn't do anything in park, but I wasn't too sure. Thx for that tip
