Transfer Case Noises?

check the axle shafts there may be a u joint going bad or something may have gotten caught in it.

Would it be a joint if it only happens in 4wd? I thought it had something to do with the front differential.

Hey Charlie,

Yes it doe sounds like the spider gears have gone bad not allowing the wheel to rotate independently of one another.

Here is what they look like, check for metal in the gear oil when you take in apart.

check it our and let me know

chevy 4 wheel drive makes a popping noise

check your u-joints on your front drive line, it's usually the one on the transfer case

i checked them and they all feel snug how would i know if they where bad

i took out my front axels on both sides and they looked fine as well no big metal chuncks came out of the diff just some small metal shavings on the drain plug

boy you did a lot of work, did you try driving the truck without the front driveline in? did you put the axles back in? it sounds like an axle problem to me, is the noise worse when you are turning? or do you just hear it all the time going down the road?

its bad when i turn and bad driving straight when i loose grip and give it gas thats when it starts making the popping noise. i did not try driving the truck with out the front drive line but in two wheel drive it dosent make the noise. i put the axel's back in and there was no wear on the teeth.

CV axles can be deceiving, try raising the truck and hold the wheel with one hand and the axle with the other and see if you have any play forward and backwards and also in and out, raised up the front on Jack stands and the rear on Jack stands put it in four-wheel drive and be very careful while the tires are moving and see if you can hear the noise.

i raised the front and back on jack stands and still can hear the noise it is just as bad. the cv axels have a little play in and out but not much.and no play forward or backwards.

I have a 2500 HD that has the push button 4wd control. About every 100-200 miles when slowing 45-35mph there is a loud grinding noise and it will not quit until I come to a complete stop. When I take off again everything is fine.

Does this only happen in 4wd? Can you tell aprox where the sound is coming from?

i even replaced a hub bearing in the process on the passenger side put in a new 4 wheel drive actuator.

It only happens in 2-wheel drive and sounds like its coming from the transfercase area. I have never had it happen in 4-wheel drive and the lights on the 4wd controls do not not blink. The service lights do not come on either.

if you heard the noise when you had it up on Jack stands, where was the noise coming from? is that why you pulled the front axles? it sounds like front axles to me, but I may be wrong. unless it's the differential? did you check that while it was off the ground?

I would start by checking the output bearing from the transfer case (rear). With no tension on the drive shaft, see if there is any play where the yoke goes into the transfer case.

Let me know what you find.

it sounded like the axels but they looked fine and thats why i pulled them. i didednt take the differential apart not sure how to and worried about it falling apart and not being able to put it back togeather. I drained the fluid and i think if the ring and pinion where bad bigger piecies of metal would of came out but it was only fine shavings on the drain plug. I think i am going to replace the u-joint they are cheap and easy and one less thing to ellimanate if it still makes the noise after replacing them.

It has roughly an 1/8" of play side to side movement and moist. That is definetly a problem. Thank you! Will I have to replace the tailshaft?

ok, sorry I couldn't help much, its hard to fix things when you can see, you did not hear,ect.

wheel make scrubing noise when turning while in 4 wheel drive

It is normal for some noise when turning in 4WD. Is this when you are in the mud or snow, or on pavement?

They should be able to replace the tailshaft bearing and seal. It shouldn't be too bad as far as cost.

Let me know if you have other questions and thanks for using 2carpros.com.

wheel make scrubing noise when turning while in 4 wheel drive

while on pavement

It will make lots of noise on pavement since the wheels all turn at the same speed. It is NOT recommended to use 4WD on dry pavement.

I have noticed that when I put into 4 wheel drive that when I turn the wheels it is making alot of noise like in the transmission or wheels, but when going straight everything seems OK. Not sure if it is transmission problems or potential wheel turning problem. Please help.

when you use the 4wd, are you in the mud, snow...? You're not using it on a dry surface?

Let me know.

It is worse on cement, but was also noisey on mud when turning quite sharp. Straight ahead was better I swiitched to nitrogen in the tires and had new oil put in transfer case. The GM garage said they couldn't hear any noise and a transmission garage thought it would get better with Nitrogen in the tires and new oil in transfer case. He could still hear the rubbing type sound and thought maybe in a couple of weeks it would go away with the new oil. So far it is still not the way it should sound..in mu opinion.

Hi, when I put it into 4 wheel drive it makes a clicking noise. Can you please give me any suggestions?

If the 4wd works, check u-joints and cv joints. IF it doesn't, check to make sure that the 4wd actuator is working.

gears slipping random loud noise

Check the trans fluid and make sure it is full. If the check engine light has come on, have the computer scanned to determine if there are any trans codes stored in it.

Hi, when I make a u turn in 2wd I get a grinding noise. You can hear it but it is not loud. When I put it in 4wd and make the u turn it makes a loud boom. Sounds like something broke. It only happens on the left side. I am not sure where the noise is coming from it is up in the left front tire. I kind of wonder if it is the transfer case. Thanks.

Does your vehicle have positive traction?

If so, Is it factory or aftermarket?

Hey Guy's i have a winding noise only when i have my truck in four wheel drive also it's a manual shift when it's in two wheel drive everything is smooth no noises thanks so much

Can you tell aprox where the sound is coming from?

sounds like the noise is coming from the front end just wondering if i changed all the fluids in front and rear ends also the transfer case ?

you could try, but chances are it won't help. Have you checked to make sure everything is full? Also, does the sound change with speed? I'm starting to question bearings. DOes it change when turning?

no it doesen't change when turning and all the fluids are full . yes the noise changes with speed

I would start by checking the output bearing in the transfer case and the pinion bearing in the front differential. Check to see if there is any play in them.

Let me know what you find.
