I have an intermittant grinding on the front of my 2000 Kia when I go over bumps. the wheel bearings were already replaced because of this, but the grinding continues.


It seems as though you have changed everything.

A grinding noise is associated with something turning or rubbing against something. The only other thing that springs to mind are the drive shafts, which have splined ends. The link below will show you generic images of driveshafts
kia drive joints Google Search

Each end of the drive shaft is splined. One end fits into the gearbox and the other end attaches to the road hub of the road wheel.

It's usually the hub (universal joint that allows the wheel to turn)/ wheel end of the drive shaft that wears. It may be that the grinding noise has been more pronounced when turning? And the grinding noise is coming from just one side?

A new drive shaft isn't cheap although second hand ones are readily available. replacing a driveshaft isn't a particularly difficult job.

However, it may be an idea to get somebody to remove the brake calliper/rotor/ driveshaft hub and inspect the hub/splined end of the drivehaft. What you're looking for is worn, broken or chipped splines. If all seems okay try cleaning and repacking with driveshaft grease. It's probably the hub - the bit that allows the wheel to turn - as opposed to the splines -there's bearings inside that hub (also known as a universal joint). There's no real way of examining that hub other than replacing the driveshaft

What is the reason for front grinding when turning


This due to either a worn wheel bearing or a worn front drive arm.

The most common cause of a grinding noise when turning is a worn front wheel bearing. What happens is that the weight of the car is shifted on to that wheel as you make the turn causing the worn bearing to make a grinding noise.

What's your problem?noise when in 4wd


if its the noise that happens when you shift it from 2wd to 4wd that is most likely normal, unless it is continuing on after the shift to 4wd,The other that it could be is a universal joint that is sloppy/loose on the front slip yolk or the front wheels.to check it you nee to jack up the front end just till the front wheels are off the ground,and support with jack stands and chalk the back wheels,then try to move the front wheels from side to side to check if its a tie rod making the noise,then move the wheels up and down to see if the wheel bearings are bad or going bad.then spin the wheels seperatly 1 at a time and look and see if the u-joint is loose.you can also check the front drive shaft/slip yolk by doing this.

2005 dodge ram 2500 4x4....getting an intermittent grinding noise while driving in the front of truck..possible front differential..;....chrisdawe@comcast.net


Hi,
your description is a little generic, however, that is what we shall work on.
Is the grinding apparent whether the 4X4 is engaged or just in 4X2 mode? On left lock or right lock?

Best thing would be to put the front end on axle stands and start checking. Check the front wheel station on each side by trying to rock it top and bottom. Rotate each wheel and check for noise. When doing this check, listen for any noise emanating from the actual drive shafts to the hubs.

Drain the front differential and check the drained oil for metal shavings etc. To be honest, "grinding" noises usually are accompanied by damaged parts. It's just a question of checking each item in turn. Also check the front prop / Drive shaft for UJ's that are dry and thus will make noise. Also include the sliding spline in your check, again, if it's dry it will be noisy, and it could be intermittent.

4X4's need to have the front ends greased on a regular and generous basis.
You did not mention if you had hublocks fitted, which would be another check to carry out.

Good luck.

4 wheel drive not engaging


The neutral/foot on brake or park is only if you are shifting into 4L. If you are shifting into 4H, applying light throttle up to 55 mph shift on the fly is fine ( per owners manual ).

Operationally vacuum holds the IWE ( Integrated Wheel Ends ) out, and once vac is removed the spring engages the IWE.

Lift and support the front of the truck so the front wheels are off the ground ( take safety precautions, chock wheels, jack stands, etc )
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

- If the front drive shaft does not turn :
Shut of the truck ( still jacked up, and supported ) remove the vac lines from the IWE. The spring should push the gears in, without the vac line on.
Check the vent line ( tube that is routed into the engine compartment with nothing attached to it ), for blockages.
If the vent line is clear, and with the vac lines off the IWE should be engaged ( both front wheels locked ).
If they lock, the problem is with the IWE solenoid not shutting off vacuum to the IWEs. There is a TSB on the 2004-2006 IWE solenoids, a newer revision has been made, and used from 2007 and newer MYs.

Here is a block diagram of the IWE system
0fa4f4b.jpg
If the front drive shaft turns, I have seen some lightly hit the back of the transfer case, to free up the shift motor, with mixed results.
If you had a vacuum leak, the front wheels would be locked in, or poping in and out of locked in, causing a grinding noise ( IWE gears not engaging fully, grinding the teeth off ).

If you find a problem with the vacuum lines or the IWE solenoids, you can pull the vacuum lines and plug them, this would leave the front wheels locked in all the time. Fine for short use, don't try racing like this ( pushing a dead axle is a lot of HP requirements )

A grinding noise in the front end of my 2002 f250 super duty and its not the brakes


If it is a 2 wheel drive, it is probably your wheel bearings. If it a four wheel drive, it could be the front differential, the joints on the axle shafts, the locking hubs, or the wheel bearings. On the four wheel drive, crawl under the vehicle and grab the axle shafts and see where the excess movement is. Also try grabbing the tires and see if there is any movement. There shouldn't be any movement while the wheels are on the ground.

Banging noise in 4 wheel drive under torque. front hub questions.


Hello scotch1812, those of us that still enjoy the square headlights have to stick together! The front axle in our YJ's are dana 30 with a high pinion! The high pinion make the ring and pinion spin in a reverse rotation from the dana 30 found in CJ and TJ Jeeps. When Chrysler designed the YJ front axle, they removed the manual hubs like those found in CJ models and installed a vacuum disconnect on the passenger side axle shaft. The passenger side axle shaft is 2 piece with a sleeve that is moved into place to connect the 2 pieces of axle shaft when you shift the transfer case into 4 wheel drive. This is done via a vacuum module mounted on the axle housing. If your module diaphram goes bad you have no 4WD! If your vacuum hose comes off of the module or breaks you have no 4WD. Now when your transfer case is in 2WD the front driveshaft does not turn. The vacuum disconnect allows this to happen. As for the hubs, they are simply hubs with sealed bearings and a universal joint to allow your front wheels to turn left and right. If you hear the banging noise in 2WD it could be a bad universal joint in one of your axle shafts.

Now if you are hearing the banging noise only when you are in 4WD there could be a number of reasons. You could have a broken axle shaft or a bad bearing in your ring and pinion. Your front driveshaft could be bent or at least not straight. I would start with the driveshaft. Just lay under the Jeep (Not running! With emergency brake set!) and spin the front driveshaft. If it spins true and doesn't have an out of round rotation we can rule that out! Also, grab it and push it and pull it to check to see if your universal joints in the drive shaft are gor and tight! They can make a grinding noise or popping noise if they are bad!

Try these and let me know what you find! We will find your problem!

95 Grand Cherokee front drivetrain


Hi Terrell,

First off, thanks for the detailed description of your problem. I wish they were all as well written as yours.

It's tough not being able to hear the noise it's making. Luckily I can draw parallels to my own experiences with GC's. Mine has 'Select-Trac', which like your 'Command-Trac', enables us to shift on the fly to 4WD. Meaning, we don't have to stop, get out, lock the hubs, get back in then shift to 4WD. Also like yours, my front end was making some noise.

What was up with mine: The 'Select-Trac' on my G.C. is a lever type switch on the center console. When I switch from 2WD to 4WD it routes a vacuum line to an actuator which engages the transfer case. The moving parts are all near the T-Case. While in 4WD, going any faster than a crawl I'd hear a mild grinding/whirring sound. It increased with speed, all but disappeared as I decelerated and made me crazy.

What it turned out to be was a Vacuum leak. The 'bellows' (for lack of a better description) type actuator was only partially engaging the the 4WD. Enough to lock the drive train, not enough to fully mesh the gears resulting in all sorts of worrisome noises. I found and fixed the leak, adjusted the range on the mode rod and that was it.

You're thinking, 'That's special'.

Well here's the parallel.
Command-Trac is also vacuum actuated. The difference is it engages your hubs from the the front axle by means of a 'shift fork'. The technical name is the 'Command-Trac Axle Shift Motor'.
When applied, the vacuum actuator moves the fork one way or the other, engaging or disengaging the hubs.

From your excellent diagnosis, it sounds like 4WD isn't fully disengaging.
You were correct about the front drive shaft. It should not be spinning while in 2WD.

Qualifiers: Is the grinding sound different at low speeds? While making sharp turns?

Have another look with these new facts in mind. Check vacuum lines, lubricant in the axle.

If you get me your engine size, tranny type, etc. I can probably scare up some vacuum diagrams (on the off chance you need them).

I hope this opens new doors for you.
Comment me back with what you come up with.
Good luck buddy.
Mike
