I tried it and it seems to have corrected the problem. All I did was side the hoses part did not even have to loosen as stated in the bulletin at $0. I have provided the link below.

i had tranny rebuilt, new tires, new u joints on rear end, new wheel bearings. none fixed the vibration i feel on my feet and the humkming noise.
what i did find out is that i took off my front driveshaft and drove it the noise was gone, or to a point i couldnt noitice it. i am rebuilding that drive shaft tday ( new u joints (3) and the (cv joint centering ball joint)) i have a feeling it isnt it because the u joints felt ok wheni had the axle off. so what im thinking is that the drive shaft is being the amplifing method of the bad product, either the front differential or the transfer case. what i dont get is that i am not even in 4wd. i am in 2wd. i dod notice that the driveshaft is moving with the wheels when im not in 4wd is this normal?
i've been hearing murmuring (a bit like noisy tread tires) and other noises coming from my front-end too. i just had my whole drivetrain evaluated at a local jeep dealer, and they found that my TC bearings and VC are worn out and need to be replaced (i have quadra-trac II). when i go back to have the TC work done at the end of the month, i'm going to ask them to check out my driveshafts and wheel bearings/joints as well.
i'm curious to know if you find a solution - i'll update my findings here in a few weeks. good luck.
Also, something that just started happening is when you turn the vehicle off you hear what sounds like a vent door opening and closing coming from the passenger side under the dash.
1) my OD output unit was making a lot of noise, which explains why it was kicking in around 3rd gear. the unit sits between the TC and the transmission. the slight rattle is just some stiffness in the drivetrain - it goes away after i drive a few feet down the road after a cold start and i'm not concerned.
2) the intermittent slight (and it really is barely noticeable) slippage on sharp turns on a loose surface was another symptom of my TC (also related to item 1 above). my viscous coupler inside my NP247 is worn out. i ordered a reman. since i'd rather just have all new internal TC components and never have to worry about it again (the VC alone is more than half the cost of whole unit). both of my differentials are in perfect shape.
3) & 4) for whatever reason, these issues are gone. who knew? my dealer adjusted my throttle linkage and replaced my idler pulley on another visit, but i don't think this explains it. hey i'm not going to complain.
i will update this post again once i've had all the above work done.
1) had the OD output unit replaced, and the loud grinding noises i was hearing when the OD kicked in are gone. if you're experiencing a really noisy OD, i'd urge you to get this done if your mechanic identifies it as the problem.
2) my new TC sounds a lot better too - all new internal components. turning is also smoother (slight hangups as mentioned in previous post are gone) and handling is better (i have full-time AWD).
so, in summary, replacing the above components made all the loud grinding noises i was describing go away. nothing was ever wrong with the engine, just had some noise issues that were signaling component wear/tear (142K miles) that i wanted to address before they really became a problem.
did you ever figure out the noise from your jeep?
Have you definitely ruled out the passenger side sway bar?

But directly to your response, would it make sense instead of replacing the passenger side sway bar just replace the bushings?

Although the vibration occurs when weather is HOT & when i needed to use my air conditioner, it does vibrates more & it is LOUD!!!! super annoying..
All my oil temparuature inside my dash board is normal as well as engine temp.
I took my car to my mechanic, he plugged into diagnostic test over the computer system but nothing came out abnormal. He suggested to take the engine out & go from there.. however, i'm afraid that it will cost me over $800.
anybody had same problems previously, please let me know.
it would tone of help!!!!
When I turn to the left (usually backing up) I still get the popping sound. Another line-up shop has made a speculation what the cure is but I won't share that with you until there is positive results. It appears at this point the "popping noise" may have more than one origin. More later......
just replaced all front u joints and wheel bearings- noise she be gone!!!!!!
save some money and get the balljoints changed while they have it all torn apart its worth the extra 150 bucks.
hope that helps- the popping noise comes from the bearing snagging on the spindle when you change the angle of the wheel by turning.
Merry Christmas,

I took my Jeep to the Jeep house and had it checked out. I am not confident of the answer I got but I was told that I needed to replace the front brake caliper with a new design that Jeep had come out with. To be honest, I thought the answer was a bit flaky so I just left it. It has gone on for some time now. I thought I would try one more time but, no, I can't say that I have sorted it out yet.
I just changed my front rotors and the popping has stopped. The rim of the rotors was really pitted. The rotors were rusted on there pretty good too. I had to take a dead blow hammer and beat both sides off. I replaced the rotors and the noise has stopped. Hopefully this was the issue. Good luck.
