Rear end acted up after manuallel putting car into 4 wheel drive.
« on: October 11, 2011, 10:42:42 PM »
Today after getting my Eagle back from the shop to get its 4 wheel drive manually engaged. At first it was fine and did about 60 down the road but later tonight when I went to leave for college about after 15 minutes of driving and getting gas something went wrong with the rear end. It sounded almost as if the engine was over revving and there was a weird almost squick/scrapping sound almost as if something was not engaged all the way. The odd thing is that the sound was coming from the rear axle. When I tried to put it into gear a few times after shutting it off it still made the noise and when I put it into drive it would not move, even the front axle was not moving which I found odd as it should have been in 4 wheel drive. Was this just the 4 wheel drive messing up or is it something worse like my rear end.

It sounds like it popped out of 4wd and is between 2 and 4wd.

Thanks that is what I am hoping it is. Hopefully not the axle fracture thing. What is the best way to put it into 4 wheel drive manual that is guaranteed to stay that way, is there a way to make it permanent. Will running it to long this way cause damage cause my dad did listened to it for a few minutes while he told me to add some gas while in drive. Also why would the noise be coming from the rear axle and not the front.

If it's 1/2 way, hopefully you didn't wipe out the viscous coupler.

Also just wondering but what would happen if I replaced my Transfer case with a 119 which only has 4 wheel drive? Can it be done on a 1984 Eagle.

It wouldn't go anywhere and yes, a NP119 will fit as long as the front axle didn't disengage you'd be okay.

Thanks, how would I engage the front axle. Is it a hard or expansive thing to engage the front axle and install the 119? It seems with the 4 wheel drive system that would be the easiest compared to switching it into 4 wheel drive manually and hoping it stays there. How would you permanently switch a 1984 Eagle into 4 wheel drive? Permanently. And engage/lock the front axle on a 1984?

If the tcase was put into 4x4 and teh front axle wasn't. the tcase is likely dead. The viscous coupler needs BOTH axles engaged to work properly or it slips till it self destructs!

Would the car still drive fine until it self destructs, because it seemed to run fine until this happened. Do all model year eagles require that or did they ever change it? When the T-case is manually changed to 4 wheel drive is the Front axle locked automatically?

I will have to ask my mechanic to see what he did, supposedly he has done this before. He said when I picked it up that he checked and the front tires were defiantly gripping as he put it(tried it out on some gravel) and I did noticed a difference in the way it felt and handled.

If the front axle is vacuum, sometimes they don't stay engaged (almost all '82 to '86s with NP129. NP128s went back to non-vac for '86 then NP129 came back till the end of production)

Thanks, that is probably what it did. Is there a guraunteed way to keep the front axle engaged. My mechanic did mention the houses going to the front axle.
