SOURCE: Hubs will not enguage when set to auto

the hubs on that truck are a vaccum controled hub, when the swithch is turned to 4x4 the vaccum control solenoid (on the fender) applys vaccum to the hub and locks- you can put a vaccum gauge on the hubs- if a leak is found thre is an o ring and an axle hub seal that needs to be replaced... if no leak is found at the hubs check the vac. lines and solenoid.goodluck

SOURCE: steering wheel shakes above 40mph, what could be

the wheel shaking sounds like a wheel balancing problem and the no steering response is either some loose ball joints or a bad gear it will need to go to the shop for both

Lift and support the front of the truck so the front wheels are off the ground.
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.

1993 4wd does not engage. Any particular area to look first. Auto hubs no noise. Light indicate 4wd is on. Any commen problems?


A bit hard not knowing the make or model but with L300 and alike with auto hubs they rely on the tailshaft spinning faster to engage the hubs similar to the operation of a limited slip diff, it only engages when needed. If you want to test it make sure you place all 4 wheels on stands or you will get hurt

Kia sportage not going into 4 wheel drive when selected could this be diaphrams ?


with 4wd engaged check that the front tailshaft to the diff does not turn more than 45* if this is ok and no 4wd light check bulb switch and wiring. if light ok you will need to track down vacuum leak to drive hubs fault { common fault } you can check 4wd operation by raising one front wheel with handbrake on and car in netural select 4wd with engine running if 4wd ok raised wheel will not turn more than 45* by hand and will spin free when 4wd disconnected

What is auto 4 wheel drive?


Auto 4 wd is when the Silverado's PCM takes readings from the front and rear driver shaft and when there is any detection that the speeds are different. The Auto 4WD will activate the transfer case to lock it self to 4wd until the front and rear drive shaft are running at the same given speed of rotation.

Thank you for using fixya

Front drive shaft not fully engaged in 4WD, with truck on stands all 4 wheels do rotate but if i stop front wheels the front drive shaft is not engaged


Hi,
Do you have auto locking hubs on the front wheels, or manual locking hubs?
If you have auto locking hubs chances are they are not engaging properly and will need to be removed and spline sets checked for broken teeth on locking hub and locking shaft.
If you have manual locking hubs then check that they are firm when turning to engage them in the lock position.If they are light when engaging them to the lock position then they my have broken/worn out the locking hub and spline. Also check that the engaging spring inside the hub has enough tension to engage the hubs they may be broken. If the hub are all ok then you have a problem in the transfer box, where the 4WD lever is not meshing the transfer box properly. Hope this helps, let me know how you get on.

I have a 2000 4wd tacoma with manual locking hubs and the 4wd does not seem to be engaging after locking the hubs and shifting the lever into 4 hi or 4 low


Sounds like one of your hubs is sticking and not engaging. You can check them by engaging the hubs and the transfer case and jacking up each front wheel independently if it doesn't spin your good, if it does you found your problem. As far as fixing a hub goes, it may be just dry and need some grease, or there are some very good aftermarket hubs available from Warn.
Hope this helps

How does my 4x4 push button locker work in my 1989 chevy K1500?


That depends a lot on how your truck is equipped. GM uses several different 4 wheel systems including AWD, Part-Time 4WD, Full-Time 4WD, and ON-Demand AWD. Then there is another version used on some trucks that is a combination of 4WD and On Demand AWD. - it gets a little confusing but each system as slightly different charachteristics.

Genericly speaking, if you have the push-buttons on your dash that say "4-HI", "4-LO", and "2HI" and/or Auto-4WD , the transfer case has an electronicly-controlled stepper motor which shifts the transfer case into the selected mode. An electric solenoid/actuator then engages/disengages the front differential for 2-Wheel or 4-Wheel modes. One push of the button and it shifts the transfer case and engages the front differential.

That's much easier than the old days when you had to stop the truck, get out (Sometimes in the middle of a big mud hole) and lock the front hubs then get back in and play with the lever in the floor to get the transfer case to shift into the desired mode.
