Messages: My truck clunks when i put it into gear,sounds like a bad u-joint,but they are good. Could it be the chain in the transfer case that has stretched some? Messages: 2, I had that same clunk you are describing on m 80 GMC.

That truck has a TH and NP gear driven transfer case. The way I found the problem was my truck started smoking at highway speed, I mean bad. Drove straight to my buddy's shop when it happened. We found the transfer case overfull, and the trans low on fluid. There is a sleeve that connects the transmission output shaft, to the transfer case input shaft. When we dropped the T case we found that the sleeve was shredded. The splines were almost completely gone. Luckily the shafts were fine.

If you want to "check" you chain, and replace it, it's easier with the transfer case out. If you want to check the coupling sleeve I am talking about above, you need to drop the t case. I think to find your problem I would begin by checking the sleeve. You t case is aluminum, and much easier to remove than a NP or NP cast iron case. Chuck SmithApr 29, Chuck, the rear driveshaft has some play in it. It does it in both forward and reverse. I has done it since i have owned it 3 years it sounds like i have another summer project on my hands now The tranny fluid is ok.

I am also glad it is not that NP transfer case i know how fun they are to work with. I have the same clunk in my 81 K Messages: 3, TomatoRedGMC - yours sounds like a bad u-joint.

That would cause your clunk,and cause a vibration as well. The vibration is also what is causing your bolts to back out,and come loose. Up and down,side to side,while turning it?

Some other things to check would be the differential backlash,loose or broken leaf springs. Loose u-bolts,etc,etc. Wyldman the play is when you turn it. There is about an inch or so play when you turn it.Gain extra benefits by becoming a Supporting Member Click here find out how! Send Private Topic View Profile.

At the end of last winter I was pulling up out of my driveway when my transfer case made this horrible sound. It sounds and feels like the chain is skipping a tooth on every revolution.

It bangs real loud and jerks the truck when iI accelerate on a loose surface like gravel. Seems to do it worst in 4hi. I dont know much about these tcases but my buddy says they have some sort of clutch system inside that is wearing out I've neber heard of such a thing That's where a component inside the transfer case rubs a hole though the case and you lose all your fluid and then eventually your transfer case grenades itself.

Its a common problem. The hole will be pin sized. Sold: I experienced the same problem. There will be no evidence that you've lost all of your fluid. You can fill the fluid reservoir and the noise will still be there. I drove the truck for miles upon miles with the noise. Finally, I looked on the internet one day and found a junk yard that had a used transfer case.

I ordered it, swapped it and no problem from then until I sold the truck. I now have an 06 Chevy Duramax 4x4 and I'm a little more delicate with checking the fluid and not being so hard on the 4x4 option.

How do I Troubleshoot a Transfer Case That Makes a Clunking Sound When Power is Applied?

I usually take my time and engage the 4x4 as recommended by the manufacturer. It may save the x-fer case and save you a few bucks down the road. You'll need to look on the x-fer case for the model number that you have.

Then look around for one with the same number and low mileage and you'll be in good shape. Gerald Lafayette, La. I confirmed it is topped off with fluid. No Leak If you've ever busted a tooth off of a ring gear in the front end of a 4xLog in.

After 1 week I would notice a clunking noise when pulling away from a dead stop about 10 percent of the time. I took it to dealer and he couldn't replicate the noise, but then he only test drove it around the lot.

In the last week it has gotten worse and shows up more often and even when it shifts from 1st to 2nd and only about 20 percent of the time. I'd like to take it back to them but I almost think they are trying not to find it till after the warranty is up. Anybody have any thoughts or advice?

Joined Dec 1, These sorts of noises can occur and are sometime common. Not always though. Is it still under warranty? The truck has 35, miles on it. The dealer said he couldn't replicate the noise but according to my trip meter he test drove it for less than 1 mile. It feels like the rear end is shifting back and forth or the tranny is moving. It doesn't feel like an internal problem. If it's normal then I can live with it but If it's moving around I have to believe it's causing damage.

The 99 Sierra I traded for the 05 had miles on it and it made absolutely no noise whatsoever. It sounded more solid and I guess I'm just paranoid that it's going to cost me a bunch of money I don't have.

Joined Sep 15, My Dad had a 01 that did the same thing. After takeing to the dealer 3 times they finally told him that it is normal and that there is nothing that they can do.

To me it sounded a little funny that they found the problem but could do nothing to fix it. If i remember correctly it it something in the trans. I am not sure though. Like the shift soliniods. Joined Jan 12, Log in.

This noise also occurs sometimes when i am going down the road and the truck shifts i will hear it not as loud as reverse. The TC leaks on the front seal where the rear drive shaft goes in but i know there is fluid in there because i have checked it.

I was told by a mechanic that the chains are getting worn out inside after only k miles he said additive may help. What do you guys think? I have a hard time believing the chains get worn out after k miles.

If you beat the piss out of something, you are going to break things.Having the flexibility to shift on the fly from two to four wheel drive without having to get out and lock the wheel hubs is a luxury that most of us take for granted, especially during a snowstorm.

Many of today's vehicles are equipped with part time four wheel drive systems, which will engage either manually when the driver selects a switch or automatically when the on board computer senses that wheel traction is reduced by weather or road conditions.

The physical part of the vehicle that activates this action is the transfer case, which has an output shaft that delivers power to the drive axle. From time to time, the seals that connect these components together can dry up, wear out, or break.

If this occurs, they will have to be replaced by a certified mechanic sooner rather than later to avoid further damages to the vehicle's drive system.

The transfer case output shaft seal is located on the transfer case of four-wheel drive cars, trucks, and SUVs.

The transfer case completes the activation between two-wheel drive neutral, to low four-wheel, and then to drive four-wheel. Inside the case are a series of gear reductions and chain drives that work together to accomplish their task of supplying power to the drive axles, making the vehicle four wheel drive. The transfer case output shaft is the part that connects the case to the axle. The purpose of the transfer case output seal is to prevent fluid from leaking out of transmission, where the transfer case is connected by way of the transmission's input shaft.

The seal also helps to keep fluid from leaking out of the front and rear output shaft to the differentials, which keeps all metal components properly lubricated for extended use. If the seals leak, fluid escapes and is no longer able to properly lubricate the interior components of the transfer case. Eventually the parts inside will wear out and overheat.

If this happens, the transfer case will be rendered useless and the four-wheel drive operation will not work.

Over time the transfer case output shaft seal can fail, and when it does, will display a few symptoms that will alert the driver that a problem with this system exists. Noted below are a few of the common side effects of a damaged transfer case output shaft seal that should be replaced.

The seal that keeps fluid inside the transfer case and thus the transmission is vital for the smooth operation of the vehicle's transmission. When fluid is leaking from a broken seal, it reduces the volume of fluid that is currently working inside the transmission. A loss in fluid pressure also occurs, which will make shifting gears more difficult for an automatic or manually shifted transmission.

If you notice that your transmission is having difficulty shifting to higher or lower gears, you should contact a certified mechanic as soon as possible to inspect this problem and offer a solution. When the output shaft seal breaks or wears out, it also can cause noises to appear from under the vehicle.

In many cases, these noises are caused by the reduction of lubricants inside the transfer case or metal-to-metal grinding. It's pretty obvious to most vehicle owners that metal grinding together is never a good thing, so if you hear noises coming from the area where your transmission is locatedcontact a mechanic as soon as possible.

In some cases the loss of fluid will cause the vehicle to jump in and out of four wheel drive, when it is supposed to stay in this operation. This is commonly caused by broken parts inside the transfer case that control this operation.Log in.

Joined Feb 1, And it sounded like it was coming from the transfer case. It made the same sound when starting from a dead stop, and when you shift from park to drive, or drive to reverse and vice-versa.
