The Grand Cherokee 1998 5.9 V8 magnum 46re. It has a Dana 30 front, Dana 44A rear LSD. With the NV249 transfercase.
I should also note, that 2 days ago prior to all this happening my Jeep was squeeking underneeth. I thought it was suspension went down wiggled stuff. Found out it was coming from the tranny. It was coming from a black sheethed cable. The cable connects to the throttle valve lever where the TV return spring is at. After that lever there is another cable connected to it that goes up on top of the transmission. That cable was rubbing on something making the squeeking, since i moved it a little the noise went away.
Then a few hours later all this poping/ slurping/grindingish noises started happening directly under the shift handle in the Jeep. I just went down there again and pushed up on the tranny and it was poping on top. I reached up there started to wiggle stuff and the poping i believe went away.. But that slurping/whirring or whatever noise is still there.. As i said tho the poping noises i can feal through the main shift handle.. if i put my hand on it i can feal the poping coming from it, but it seems that was just vibration from something touching the roof above the tranny i guess... not ruling this out yet..
When im in park, however and rev the **** outa the engine to 4500-5000krpm or even 2-4k rpm. There is no noise. i put in neutral holding the brake standing still reved it again and still no noise.
Once i start moving tho abot say 10mph the noise starts again, and it seems to go up and down in noise volume as the Jeep shifts when the RPM's go up and down. I dunno... it hasnt slipped, shifts like clock work. went near 100mph on the parkway and shifted beautifully. But that noise is just horrible..
I talked to my mechanic friend just now, he said if it doesnt do it when in park and only when moving then its probably the spedometer cable needs lubed. Does this make sense ?
This is the black cable i was messing with on top of the tranny to stop my squeeking noises then all hell broke loose after i move it a little.
