I've been hearing a noise in 4 wheel drive and thought I had it narrowed down to my right front hub. I replaced that and the noise is still there. Its a growling noise that increases in pitch as the vehicle speed increases. I think I have ruled out the T-case and the trans.(5-speed), as I had it in 4WD yesterday, I was coasting and slipped the shifter into neutral and the transfer case into neutral-still the noise was there until I came to a stop. If the hubs are locked in and your moving, as I was with the trans. and T-case in neutral, what still turns? That has to be where my noise is from. I also noticed that when in 4WD, when I go to reverse to back up there is a pop from the front end, then it does it again when I go forward(which I thought was my hub).I would greatly appreciate any ideas you guys might have. THANKS!

Wheel bearing
I re-read, do you hear this in 2WD ??
Do you have Auto Hubs ??
Is this a stock of lifted truck ??
SideKick or Sammy ??
If the hubs are locked everything in the
drivetrain from the hub to the T-case turns,
no matter if you have the T-case and/or Trans
in neutral

I just hear the noise in 4WD.
Sorry to leave all this out before,,, Its a lifted kick,2" coil spacers-4" body lift, auto hubs.
-
I can hear the T-case making a noise
when the hubs are locked, it's the chain
going around, you might check the oil in
the T-case, change it too while you are
under there.
Growling sounds are bearing related
usually, you might have a Diff bearing
going out, have you checked the fron diff
for oil or contamination of the oil??
-
I don't think this is normal T-case noise(wish it was). I did check the oil in the diff. and t-case. Looked like it could use changeing but they were both full. I hate when I get stumped on stuff like this! Does that popping noise up front when I go back, then forward again give you any other thoughts? I noticed it doing that in the junk yard the other day(which was very muddy!) Thats why I really thought it was the hub. Hey, by the way, THANKS for all the help! You helped me several months back with some questions I had on my steering and shifters, when I did my 4" body lift. ;D

You should just swap the hubs if you have some readily available at a junkyard to see if that helps.
Yeah, Wildgoody is definately a man amung men ;)

growling sounds like bearings, or could be brake pads rubbing continuously on the rotor, maybe a stuck rock?
now the 'popping' sound? i got that too, apparently its my rear tail shaft, the uni joint is worn a bit and something about some pins unseating..... sorta like stuck drum brakes. could be from your front drive shaft?
i dont really know what the problem is, but just some other things to look out for. hope this helps.

If you only hear the noise in 4X4 try lifting all four wheels off the ground by putting it on jack stands.
Run it in 2X4 and see if you hear anything. Then put it in 4X4 and see if you hear the noise. If you can hear it get a hold of a mechanics stethiscope and try to isolate the noise down the axle tube especially where the bearings are. It could be a carrier bearing in the front differential. Have you checked the fluid in the front differential?
-

I second that.
A few years ago I heard that sound also, and it turned out my bearing were worn out to shit...I had them replaced with a nice new set made in Japan. (Broke the wallet though >:( )
-
Thanks for the compliments you guys
OK back to the problem, Popping can
be the auto hubs unlocking and relocking
get those off and drive the same way, see if
it still does it, or better yet, get some Man
hubs and replace those autos, they are
more prone to breakage.
I had some worn CVs that when I was in
4WD sounded like clicking of a roller coaster
as it goes up the incline, are you getting this
kind of noise
-
I did put it up on jack stands last week, but didn't hear the noise then. I've noticed when I drive it ,I usually have to get to second gear before I can hear the noise, then it will continue until I come to a stop. When it was up in the air I shifted to 2nd and gave it some throttle but still didn't hear it. WILD, it doesn't really make the climbing roller coaster noise you were describing, it's more of a whine or growl. I'll put it in 4wd tommorow and take it for a drive after I remove the hubs,,,see if that makes any differance and let you guys know. THANKS AGAIN!!!
-
Sounds like the wheel bearings to me. The first sign of them going bad in my kick is when I put it in 4x4. I guess it's the extra pressure from the wheels pulling instead of just rolling. Mine starts out kind of sounding like a duck quacking then as it gets worse, it turn into a growling/grinding noise. Have you jacked up the front and checked the bearings yet?

Check your front pinion nut it may have worked loose. this would cause the pinion gear to walk back and forth as you go into forward and reverse, It will ruin the gear and the bearings, the fact that you have locking hubs means the front ring and pinion is not moving unless you are in 4whd. Thats why you only hear it in 4whd. Had this happen once in a YJ i had.
Thanks

Good Point Wayne :)
They say the biggest problem with most
vehicles is the loose nut behind the wheel
;D

So thats what it is ??? I'll check on it if they ever take off this straight jacket :o I hate typing with my tongue.
Thanks

I'll be over to untie you,
then you can use my Kick
to figure out some tube doors
I bet the bender is hard to use
with your tongue too ::)

Dude your on. you still got a line on a 4X auto 16v? I need another project ;D NOT. the holiday time is busy this year but we should hook up to do some fab.work I need somone to read the degree wheel. Its hard to see in that position ;D
Thanks

I'll pm ya my cel #

I tried taking the hubs off and driving it today, noise still there. Thats about all I did with it today though. It was COLD!!!in Iowa today! I will check the pinion nut tomorrow and take a little closer look at the wheel bearings. Thanks again for all the help!!!
-
If the pinion nut is loose, zap it on
with an impact, but not too far, there is
a "crush sleeve" that keeps the bearings
pushed into the races, if you over torque
the nut, it could make the bearings too tight,
that is if they aren't wasted from being loose.
Also I hope your gears are OK, when you break
a housing the misalignment of the gears often
chips and strips gear teeth off :o
Then use a pin punch to knock the thin edge
of the pinion nut into the groove in the pinion,
this keeps it where it belongs

If youve run it that long the bearings are gonna be shot and the teeth on the gears are gonna be bad but if you can stand the noise they will run a long time in trail duty. really you should use a torque wrench to tighten the nut but what ever you do set the lock and if the nut is bad get a new one you have to set the lock or you will be toast again.
Thanks

i had the same grinding/howling noise front the front. i took it to my mechanic friend and he said it was the wheel bearings. and he was right. i just replaced all 4 wheel bearings and bearing races and now the noise is gone!! i thought it was the front diff when i first started to hear the noise but it wasnt it. changing the bearings was pretty easy but you need a deep socket to get the bearing nut back on. let me know if you need some info on the bearings...its still in my head from last weekend! it only took me about 3 hours to change both sides
-
Just another case I'm familiar with ...
I had a bud who had a speed related frontend growl in his 88 chebby. I was swearing it was a wheel bearing. turned out his pinion had a split a penny would fit into.
Point is ... hard to diagnose on the web :)
-
Yep good point but he said it only happened in 4whd. wheel bearings turn whe the car rolls so they make noise then too if they are bad.
It is nearly impossible to do real diag work from this keyboard but we all love to take a swing at it ;)
Thanks

I think Its the drivers side front wheel bearing. Had the front end up checking things out again and that wheel bearing is bad. I will have to wait until my next check to go get it, ($50!!) Spent too much on Christmas as usual. Im anxious to get it installed to know for sure, but I think that is my noise. THANKS EVERYBODY!!
-
All 3 of my trackers make noise in 4wheel drive, I dont know how much noise youre talking about, but you are going to hear the chain drive working if youre in 4whell or 2wheel with the hubs locked. Did you ever change your tcase fluid?
-
I was just going to let this go. It wasn't the wheel bearing and I figured when it broke(whatever the problem is) I would fix it, but ...... I put it up on jack stands for the second time, ran it up to speed through 3rd gear and there is no noise. Its only when its on the ground and thats should tell me something, but what? I thought I would ask you guys again for help. What (in 4wd) would make a groaning/whining noise, that increases in pitch as speed increases, but then is not there when the vehicle is off the ground(and ran through the gears in 4wd)?????
-
The CV?
On jack stands, the joints are extended and might not have the groan, but when weighted, ...
dunno, just a thought.
-
I was kinda thinking the same thing. Only thing is, that when I turn sharp in a circle to either side they don't make any noise. I always thought if CV's were bad they would clunk when you cranked the wheels?
-
CVs click when bad
T case makes noise, but all the time

Bearings woul dmake more noise with the weight of the vehicle on it ;)
