kdukes4 ya i was going 45-50 when it popped out. sounded pretty much as you described above, i can't recall exactly how it sounded but you're right on target, i just knew it was my 4H and hit the clutch and shifted as fast as i could. this morning i disconnected the linkage rod right at trunnion bolt away from the shifter inside the cabin. made sure the lever was in 4L and then went underneath and moved the tc shifter by hand into 4L, then secured the linkage. to be honest i can't remember if it looks much different than before, but in 4L it sounds fine in 4H it sounds fine till i go above 25mph, then i get that grinding noise again. however, the more i think about it, i'm wondering if i'm just being over sensitive to the sound. being in 4H this summer the dirt roads and bumps are so loud that maybe i could never train my ear to my 4wd? i gotta get another ear in my cabin to get an opinion. or maybe my linkage is loose? i only get the noise when i put my foot on the gas, when i'm coasting, its on/off with no pattern. eh i didn't pop out of gear though, so that makes me think that i have the linkage close to, if not correct

I would really like to know that as well. By my way of thinking, as long as it is attached securely, it should be okay. But my way of thinking is usually wrong.

Right. After the lift I was unable to get into 4L, so my friend that helped me got under there and loosened the linkage, I put it in 4L, and we had just enough of the rod left to get it adjusted without using the drop bracket thing. However, now I am thinking about installing it anyway to allow for more play because I'm wondering if it somehow contributed to the problem.

I only got that when I tried to get into 4L before adjusting the linkage because it wouldn't fully engage.

When it happened to you did it sound like a high pitched revving sound almost? The first thing I did was look at my tachometer because I thought the engine was over revving. And then, like you, as soon as I put it into 2H it stopped. How fast were you going?

I'm going to change the fluid next week. Hopefully I won't see any metal in the oil.

Weird - when I logged off last night this thread had 0 responses, and now I see it started something of a debate. Anyway, I agree that 50mph sounds fast when the roads are snow covered. However, at 50 I was actually being passed by other traffic, and I think I only passed one car, an old lady with a look of terror on her face going about 30. I think sometimes it is actually safer to be going at least somewhat with the flow of traffic. The guy going way to slow can be as much of, or more of a hazard.

I agree with the others regarding the use of 4H. I pretty much put it in 4H anytime the road is completely snow covered, even if it's only 1/2"

dj_chizzle sounds like we agree after all

my apologies for the slight

s3nt3nc3d I can safely drive up to around 50 on a snow covered highway in 4wd...depending on the road conditions. If it's deep and/or full of ruts, I should and do slow down as it's very easy to lose control even in 4wd. If it's got about an inch or so on it, just enough to make your ass end get a bit squirrely when the tires slip, you can regain a LOT of control back by simply engaging it into 4wd. Ever notice how front wheel drives cars can maneuver on roads after a light dusting without hardly breaking a tire loose whereas a rear-wheel drive pickup truck is probably spinning their tires at every stop sign/light and fishtailing at every corner. Are you saying those front-wheel drive cars should drive as slow as the pickup trucks even though they still have complete control of their vehicle? Same concept...you're just changing your drivetrain over to get control back.

If I'm on the interstate and it's covered in ice, I am NOT one of those people flying past everyone in the left lane in 4wd thinking I'm invincible...typically I'm the guy chatting with the truckers on the cb radio joining in on their convoy which is cruising at a safe and comfortable 40mph until I either reach my destination or the road conditions improve.

I do agree though, 4wd does NOT help you stop any faster or do anything better on a sheet of ice so you should NOT attempt to drive the speed limit...or even as fast as the vehicles in front of/behind you. You should drive at a speed where YOU, the driver, still have reasonable control of your vehicle. If you're sliding all over the place...you need to slow down or get off the road, because you're now endangering yourself and others.

kdukes4 i don't think sentenced or i are saying to throw it in 4H and hit the pedal to the medal on the highway, but with such a short wheelbase, i notice a tremendous difference in the change of traction between 2w and 4H. like sentenced mentioned the 4H keeps your back end from fishtailing out behind you. you're right, doesn't matter what wheel drive you're in going fast on slick snow and you want to stop, but handling wise, i think when you're in the snow, 4H is a good idea. even though most highways do well at keeping the snow off of the road, when the outside of your lane have snow around them and you catch a tire on either side, you're gonna like the fact that you're in 4H and not 2w. people can choose to drive how they like, just realize you're responsible for your actions, and your actions can affect your own and other's lives. lets get back to the subject ya?
01-01-2010 10:10 PM
dj_chizzle I get why people use 4Hi to maintain traction, I'm just saying I don't believe people should be driving at such high speeds on snowy highways. Just because you CAN doesn't mean you SHOULD.

Do you people think 4Hi will help you come to a stop from such high speeds on a slick snow covered surface???

Sorry if this is getting off topic. I just don't want any newbies coming in here thinking "oh sweet now that I've got my jeep I can go drive 50mph in the snow woohoo"

4Hi is great for keeping your ass end where it belongs when driving on snowy highways...you can drive up to around 50mph without any control issues in 4hi since you've got your front wheels pulling you when your rears start to slip, whereas in 2wd, every time your rear tires start to lose traction while accelerating, you start fishtailing.

Loud Whining Sound! Help Please!

I was driving into work today on the freeway and the roads were snow covered so I had it in 4 HI. I was about 7 miles into my 10 mile commute, cruising along at about 50, when suddenly I hear this VERY loud whining/grinding sound (like high acceleration revving almost) coming from directly underneath me. I shifted the tranny into neutral (6 speed manual) and started to coast to the shoulder and the sound continued. I shifted the transfer case into 2WD and the sound immediately stopped. I then put it back into gear while coasting and drove in the rest of the way in 2WD.

Once I got off the freeway I pulled into a parking lot and crawled underneath to see if the T-case linkage was broke or came off. It looked fine so I re-engaged 4HI and drove in to work without any more problems or scary noises.

I have a BL/MML and the linkage is adjusted almost all the way out. I did not install the drop bracket as it didnít seem to be needed. (See pic) Iím wondering if I didnít have the t-case lever in 4 HI completely when I first engaged it. Is it possible to engage the 4WD lever just past 4 HI, (closer to neutral but not in neutral), yet have it work in 4 HI then suddenly something happen to cause that horrendous sound? Scared the crap outta me!

Any other thoughts?

[IMG][/IMG]

Also, what are the chances that that terrible noise resulted in damage to the t-case?
