Question about 2001 Chevrolet Blazer

1 Answer

4wheel drive sounds really bad...

When it is in 4-hi it sounds like it is "winding up". Then when I try to change it back to 2 it stays in 4 for a while and then I hear a huge thud, and it's back in 2 again. It sounds like I have hit something when it finally goes from 4 to 2.

96 explorer disengages 4wh low but does not engage 2wheel


Does it shift to 4wd high range ? If so then shift to 2wd . What is going on here is the transfer case motor is stopping due to the motor position sensor has gone bad which means that you replace the transfer case motor assembly. But if you wish to make it a 2wd for awhile then remove motor and manually turn shaft . This can be done by raising and supporting rear axle truck in park remove motor turn shaft slowly with pliers and rotating the play in drive shaft. There are stamped markings on back of case showing gear positions..

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.



HOPE THIS HELPS.

I have a 99 Chevy Blazer, I have had it for about six months or so. The past month and a half, it pops out of 2 wheel drive and into 4 wheel drive (sometimes blinking back and forth between 4 hi and 4 lo)....


I have the same trouble. It seems a relay is keeping it in 4wheel drive. I havne't solved the trouble yet. It may be a loose or corroded wire in the connector to the TCCM located in the passenger kick panel. Dealer part about $450 or more. For the moment I took out the fuse for the 4 wheel drive. It is located in the lower right hand side in the fuse the box under the hood. It disengages the 4wheel drive and I replace the fuse if I need the 4wheel drive.

Change clutch


Sounds like transfer case issue if 4 wheel drive works and 2 wd does not. Clutch slippage would be worse in 4 wheel drive more than 2 wheel drive, more to push.

Suspension Vibrates while driving every 3-4 minutes VERY LOUDLY


I had a 1999 Expedition with a similar problem. They had a recall on a 4 Wheel drive switch that would change by itself. On the models with air suspension it was worse because the 4Wheel drive setting would automatically raise the vehicle. My Expedition had an automatic setting and then electric lockin settings to stay in 4 wheel drive. They were skipping all over. The dealer knew about it and replaced the switch. It fixed it. But there were also some bad front hubs that growled.

2000 v10 250 wont come out of 4wheel drive seems to be stuck in 4w hi grabbs on sharp turns inside selector works


push button 4-wheel drive??? If so maybe the transfer case motor? look on back of transfer case for something that looks like a window motor.... have a friend, while on level surface in nuetral with brake depressed, try pushing 2-wheel button while you lightly tap on side of window motor with light weight hammer or wrench. If this doesnt work then motor may be bad.
