Noises under acceleration/turning and rough idle
recently I've been having some troubles with my jeep,
I'm getting noise in tight turns and a bit of wheel hop .. now I assume this is my transfer case (quadradrive .. viscous couplers?) acting up .. so I'm wondering, what fluid is best to put in there, and where can I get it from? (I'm assuming its a dealership only thing?) Also, how do I change the transfer case fluid? Sorry for the ignorance, I've never owned a true 4x4 vehicle before, so any insight is greatly appreciated.
Also, my front differential makes a horrible whining noise whenever I'm in 4low, and the shifting is very rough in 4low .. very jerky on acceleration and deceleration so I assume it needs new fluid as well, so what kind of fluid should I put in my front and rear differential, and is there a specific gasket I can buy from chrysler for putting it back together, or should I just use sealant?
And to keep with the "do it all or do nothing" scheme of things lol, my transmissions been acting up lately (rough downshifts when slowing down) so I figure I might as well change the fluid in there too. How much fluid will it take, what's the proper procedure, and what kind of fluid should I get? I've heard varying opinions on amount and how to do it, so once again insight is greatly appreciated. Also, I have a tranny cooler so I assume this affects how much fluid it'll take .. also, for resealing the tranny is there a gasket I can buy or should I just use RTV again?
Also, are there any torque specs I have to follow when I'm rebolting my tranny pan/differentials/transfer case?
Lastly, My jeeps developed a rough idle. In drive at a stop light it's fine, but as soon as I put it in park it'll bounce around from 900-1000, and when I start it up it'll go all the way upto about 1900 or 2000 RPM's then fall down, but it falls really slowly, so help? I think It may be the little sensor in the throttle body, but I've completely forgotten what its called, and I can't seem to find the thread on cleaning it.
So fellow jeepers, help me out. I have a few more days off work and school before I jump into both head first again, and I won't have time to fix anything once I start school again. I wanna get my jeep in top notch running order before I start depending on her as a daily driver again.
