SOURCE: 4 wheel drive will not disengage.

I've had the same situation. I found the problem to be the Hi-Lo gear shift was not locked in place. In other words, it was between Hi and Lo. While the truck was off, I moved the gearshift from Hi back to Lo back to Hi, making sure it was in Hi gear. Then, after starting the car and traveling down the road, I found that the 4WD would disengage with the button.

SOURCE: 4 wheel drive is binding in 2002 trailblazer

the trailblazers are designed to shift from 2 wheel to AWD on the fly. BUT NOT TO EITHER OF THE 4 WHEEL OPTIONS. I'd suggest you get it to a mechanic to evaluate the damages.

SOURCE: HOWLING NOISES

Did you check your Transmission fluid and your differential fluids make sure there up and I don't know if you checked your rear wheel bearings or not, You can usually tell a wheel bearing when you are driving the car at highway speeds and you go around a corner and it get quite a bit louder Depending on what way you are turning if your turning right and it gets louder it will usually be the right side front or rear. the left usually the left front or back. some cases I have even heard Axles making a Howling Noise. Please let me know what you come up with. And Thanks in advance If I helped you out any. Bear001

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub

My ford ranger 4x4 5 spd. has started howling when I'm going down the road and it only stops when I either push in on the clutch or put it in neutral.


What speeds, does it make more noise in 4 wheel drive or the same. There are several possibilities, need more information. Does it howl in all the gears or in 5th gear only.

Loud noise when 4 high button is pressed while driving in 2 high


engaging 4wd at speed is not recommended as the syncro set up is for low speed operation only Using 4wd on hard surfaces especially with your tyres does not allow the wheels to slip and so you get torque wind up in the transmission. This prevents the gears from disengaging as there is excessive load on the teeth. To unload the wind up either drive on a grass/ gravel/ slippery surface or stop and allow the vehicle to run backwards. IT all amounts to driving technique and knowing when and where to engage 4wd. There are plenty of books /magazines that explain the damage that will be done to the vehicle running gear if run in 4wd for long periods on hard surface roads.

Mike: you may have a worn spider gear or the height is mismatched from left to right. Check air pressure. Check tire height.

I have a very loud humming/howling noise under my feet when driving. I do no that I need a cv boot. Can that cause this loud noise?


A humming or howling can be cause by a dry, worn out wheel bearing. Also tires that aren't worn evenly across the contact surface of the tire will cause a wheel bearing like noise.

Howling noise from 2006 ford escape when driving


That's a bad wheel bearing. If when driving and you swerve side to side and its loud one way and not the other or not as bad the other then its a wheel bearing. As for the metal shavings on the plug don't worry about it unless there are chunks of metal then you should have the rear end inspected.

Medium humming noise when backing up at low speeds


Probably rear brakes. Clean them up or get them looked at and try again.
