james750 Posted December 9, 2008 Share Posted December 9, 2008 When I put my truck in 4wd the transfer case (maybe the front axle) :dunno: starts to make a fairly loud and nasty growling noise, It goes away when I am not on the gas but comes back if the gears start to slow the truck down at all. I hear it very faintly (read: very) on my other np242 xjs and on my sisters np231 XJ, but not anywhere near as loud, But they are autos with AW4 so I am not sure if that makes a difference. I need the truck for DD now and cannot have the 4wd going out while driving in winter. What do you guys think the problem could be? Link to comment Share on other sites More sharing options...

GaruMJ Posted December 9, 2008 Share Posted December 9, 2008 I think I had the same problem. I hope this help you :cheers: viewtopic.php?f=2&t=12931 Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted December 9, 2008 Share Posted December 9, 2008 I would first suspect the axle... but you are correct, it could be either. You need to find out. Dissconnect and plug all vac lines at the CAD. Put truck in 4WD and go for a ride and listen. Doing this will NOT allow the CAD to operate and engage the front axle, so any noise herd will be coming from the T-Case. BTW, when is the last time you checked/changed the diff oils in your axles?

BLHTAZ Posted December 9, 2008 Share Posted December 9, 2008 BTW, when is the last time you checked/changed the diff oils in your axles? CW ...or checked the fluid in the t-case. I had one go dry on me, but never saw any sign of leaking... :dunno: . I didn't catch it in time and grenaded the case though :wall: . Link to comment Share on other sites More sharing options...
james750 Posted December 9, 2008 Author Share Posted December 9, 2008 CAD is locked, but fluids are good in the axle, where is the fill plug for the tcase? It takes ATF right? Link to comment Share on other sites More sharing options...
Pete M Posted December 9, 2008 Share Posted December 9, 2008 Fill plug is on the back side right about in the middle of the t-case. And yes, ATF. Link to comment Share on other sites More sharing options...
