I have a NP242 transfer case and recentely ive been hearing some strange noises If i step on the gas pretty hard whether im in 4wd or not, it grinds for a second then stops. Then while i was driving down the road, I heard a whining that was constant. It comes and go's. I really dont know what is wrong cause it sounds bad. Im gonna check the fluid soon. So what could be wrong besides that?

 

Have you changed the fluid ever?

 

Ive only had it about a year and havent touched the tranny fluid or tcase so no. Could fluid be causing it?

 

I would start by checking the fluid level/condition

 

Yes, I need to find a big enough wrench for it first haha, but anything else?

 

I would take it out and tear it apart. after u put fluid in it and see if that stops the noise.

 

Alright so if the fluid doesnt solve it, take out the tcase and just check everything out?

 

Yes and replace anything worn or broke.

 

Alright sounds good to me, but im sure my dad wont believe me so I might have to do it alone, is it pretty easy to take it apart?

 

Yeah they are simple. Any mechanically inclined person can do it. Lots of info online of how to rebuild one

 

Alright thanks

 

So I put my finger in the transfercase felt a part and there was sorta like blackish fluid on it. Should I feel a lot of fluid and should it be a different color?

 

What kind of fluid do i put in the np242?

 

My np242 for my 2000 takes dex/merc lll or better.

 

Thanks, I got some in there. Seems like it made a difference but I'm still hearing some weird noises
