Transfer case problems.

I'm getting transmission wind up from making a turn in my front tires when turning at with acceleration. If I coast at the same speed in the turn I do not get transmission wind up. This is in 2wd. I do not have a problem in 4wd.

1. I would suggest that you engage your 4WD while you are in full stop and/or safe range of 5mph, however as claimed by the local dealers your vehicle is capable of engaging even while driving. Engage your 4WD while moving only when necessity requires.
2. That clicking noise while turning extreme right or left would be the birfield of your axle and would only mean your front hub is still engage even though you have disengaged transfer case.
Have your front hubs cleaned of old lubricants or grease due to non usage. dont use grease as lubricants, use thick oil such as gear oil or silicone oil. and use your 4WD every now and then.

Do this first then check if you still feel somtehing is loose on your suspension and others.

SOURCE: I HAVE A 2004 TOYOTA CAMRY. I HEAR A ROARING NOISE

sounds to me like its a cv joint. if the rubber boot gets damaged in any way, dirt gets in there and really does some damage. check the boot really good. if you dont see any holes or anything it might just be the wheel bearing. id take it to a mechanic and ask him to just look at it. usually they wont charge ya.

SOURCE: Thud noise / jolt when transmission.......

Yes, I would get the transmission checked it sounds like it maybe getting ready to go out. Take the dipstick out & smell the fluid to see if it smells burnt...Hope this helps..

When I select 4 wheel drive, why does it feel as though it is binding or dragging and whining while driving?

Depending on the specific vehicle many 4WD have a transfer case that will lock the front and rear drives shafts together. This configuration is only for slippery conditions like ice and snow or very wet or off road. When turning the radius is different between the front and rear so there is a lot of feedback to the steering wheel. This is created by the fact the front set of wheels and the rear set of wheels must make the same number of turns because of the locked transfer case.

If you attempt to drive on high friction surfaces the stress to the drive train is excessive and will cause damage. The whine and the bunny hop is the drive train attempting to release this tension. If you were on a slippery surface the tires would have much less resistance turning at slightly different rates.

Also critical is the tire size need to be the same. However even with perfectly matched tires the problem on dry surfaces remain the same.

The AWD vehicles are equipped with a third differential that allows for the difference between the rotation of the drive shafts so it can drive on dry pavement no problem. Some configurations allow the AWD to have the transfer case locked which falls into the first category where dry pavement is prohibited.

Some Jeeps have a viscous coupling in the transfer case that permits limited slip between front to rear but the resistance to slip increases as the deference increases as in the event one tire is slipping
These Jeeps still have the lock up option in the transfer case requiring dry pavement when engaged.

Hope this helps?

2002 jeep wont stay in 4wheel drive low

Your JEEP is only part time 4WHEEL DRIVE as you can't DRIVE on the STREET with it, its NORMAL and nothing is WRONG.


Part-Time and Full-Time 4x4 systems...

A part-time 4x4 system called Commandtrac is in all Wranglers together with low-end Cherokees and Liberties. A part-time 4x4 system locks the front and rear driveshafts together inside the transfer case so they drive the front and rear axles together in lock step. Because they are locked together, the front and rear tires must rotate at the exact same rpms. However, the front tires must rotate faster than the rear tires during any turn so a part-time system fights that... which makes a part-time system inappropriate on a paved road because the high level of traction on a paved road prevents the tires from slipping which would otherwise allow the front and rear tires to grudgingly rotate at different rpms. Offroad this is not a problem since the poor traction of an offroad trail allows the tires to slip as needed. But when they try to slip/rotate at different rpms on a high-traction surface, the entire drivetrain is stressed which is bad for it. This problem is called "wind-up".

In reality however, the front and rear axles really don't even turn exactly the same RPMs when you're in 4wd so you still get "wind-up" if you drove in 4wd on the street even if you drove in a perfectly straight line. Why? Because 1) you can't drive in a perfectly straight line and 2) the front and rear axle ratios are usually .01 different from each other. Like a 3.73 and 3.74, 4.10/4.11, etc.. Why the .01 ratio difference between the front and rear axles? Because the front and rear axles usually have different ring gear diameters which makes it nearly impossible for the gear manufacturers to economically make the front and rear axle ratios exactly the same. And no, they are not made .01 different on purpose to make the front or rear pull more when in 4wd, that is an old wive's tale.

Finally, a full-time 4x4 system like Selectrac is available on Grand Cherokees, Cherokees and Libertys couples the front and rear axles together, but they are not mechanically locked together like they are with a part-time 4wd system. The front-to-rear axle coupling can be done via either a differential like the Selectrac system uses (just just like what is in the center of an "open" axle) or a fluid (viscous) coupler. The benefit to a full-time 4wd system is that because the front and rear axles are not mechanically locked together, the front and rear tires/axles can rotate at different rpms from each other. This allows a vehicle with a full-time 4wd system to drive in 4wd "full time" on a paved road without problem since there is no 'wind-up' problem to harm the drivetrain. You cannot get a full-time 4x4 system in a Wrangler from the factory.

The actuator under the battery runs the engagement of the front Diff .If 4 - wheel low is working and high is not then that is a linkage adjustment problem at the transfer case or a internal problem with in the transfer case not the transmission .

Grinding noise....sounds like metal

Check the disk brake pads. At slower speeds you can hear them squeak because there is less wind and road noise. The other possibility could be a bad u joint at the ends of the axle half shafts on the front differential. Check both. I really doubt it is the transfer case. You transfer case is engaged all the time. The axle is locked and engaged when you flip the lever by a vacuum motor on the axle shaft on the differential.

I have 2005 Cadillac SRX 86,000 Miles. I hear a grinding noise when I accelerate and feel a bump when driving on hyway, No sound when coasting, stoping or ideling which to me would eliminate engine or...

Grinding on acceleration, rhythmic thump on the highway... might be a bad u-joint in a CV shaft or rear drive shaft. Put the transmission in neutral, put blocks in front of the front wheels jack up the back end of the vehicle and put jackstands under the frame (do not rely on the jack alone to hold it up!). Turn the rear wheels by hand while listening and feeling for slop or roughness. Crawl under the vehicle and check for play in the drive shaft bearings, then rotate the drive shaft by hand to check for rough bearings in the u-joints. Inspect the fender wells and suspension linkage for foreign objects that may be rubbing or bumping on the wheels. Inspect the tires for uneven wear, incipient blowouts (blisters) or other problems.
If you don't find anything in the rear end, lower the vehicle, block the rear wheels, jack up the front, and repeat the check on the front wheels.
Check your transmission fluid as directed in the owner's manual. It should be at the proper level and clean, with no burned odor. If there is a problem with the transmission fluid, the noise could be coming from the transmission.

Wil putting two size tires on a isuzuvehicross make the transferre case go out.

Yes...
The tire sizes are important on any 4X4 vehicle... IF you engage the 4X4 ... or is you have an AWD vehicle...

If the tires are different sizes , front and rear... then the front and rear axles will turn at different speeds... not in sync with the gearing of the transfer case.

Unless this vehicle is being driven on snow , ice or mud.... while in 4x4 mode... this is very bad.... for axles and transfer case...

Whining/ howling noise / 2007 Durango

i'm thinking that your tires need speed balancing :),, if is not the tires then one of your bearings on the hub needs replacing or the exhaust has a hole somewhere.
