I have a 1999 mitsubishi l200 with manual locking hubs,when i select 4 wheeled and the hubs are locked there is a bad knocking noise as the wheels turn and if you try to turn its as if the brakes are seized and it wont move.there is plenty of oil in the front diff.
Have you check the driv aksel on left and right side, if you have a bad drive shaft , you shall hear a noise specily if you turn the steering to full right ore left. And so can you check the drive shaft betwen the aksel and the reduction gearbox.Have you check the oil in the front diff , if the are metall partikel in the oil? if the are mettal partickle in the oil , you must check the diff

You don't say anything about symptoms, but
1) strange noises might give you a hint
2) Won't shift into or out of 4wd.
3) you could jack up the vehicle so all 4 wheels are off the ground, (be careful) lock the hubs (if you have manual locking hubs) and start the vehicle and shift through the gears in both 2wd and 4wd.
There are a number of different hub systems so this may not work but it has worked for me on both auto and manual locking hubs. On a flat surface without traffic. Put the trans into neutral, shift the transfer case into 4x4, shift the trans into reverse and back the truck up 15-20 feet. Completely stop and shift trans into drive. See if this has locked the hubs in. If not, you can also try following the same instructions except shifting into 4wd low. Sometimes the hubs need a "bump" to get them to slip into place. Keep In mind that if the 4 wd low select works, you need to shift it back into 4 wd high before continuing! When taking the truck out of 4wd to 2wd, I recommend the same, shift to neutral, select 2wd, back truck up, shift back to drive and check. Its entirely possible that your hubs need maintenance (they're often overlooked) but hopefully this will get you going. Please let me know if thus worked or if I can offer other suggestions. Good luck!
if it has automatic lock in hubs only!! start truck, put truck in neutral, push button for 2x2 shift into reverse,back up 5to 10 feet,truck should shift back into 2x2 automatically. shift into drive and the 4x4 light should go off. if you have manual lock hubs you''ll need to unlock those manually on the 2 front wheels.w/truck in neutral and emergency brake on or someone holdling brake inside truck,go to front and rotate the locking hubs to front tire or wheels in centerof hub to free wheel.they will be marked,or should be. if not,then try turning the center of hub switch counter clockwise until it stops turning,then go to passenger side and turn it counter clockwise. thank you for choosing fixya.
manual or auto hubs?how do u now it is not engaging?.u can lift the front end up in 4 wheel make sure hubs r engaged .rotate the tire by hand ,and check to see if the drive shaft is turning [from the wheel to the front diff] u most likely have a bad locking hub.if it is not turning ur front tire is not locked up
Before you start the vehicle lock the hubs in by turning the lock out device in the hub center of each front hub. Now you can start the vehicle and while in park or neutral move the range selector on the floor to the range you would like to use. Most often you will use the 4 wheel high setting. The low setting is only for extremely heavy pulling and will throw you across the seat if you accelerate too hard. Never exceed 45 miles per hour when in 4 wheel drive as you will burn out the transmission or 4X4 transfercase bearings. Now to go back to two wheel drive. Move the floor selecter back to 2 wheel drive setting. Do this with the vehicle in park or neutral to prevent damage to the vehicle. Now you can unlock the hubs by reversing the hub lock out device in the center of the two front hubs. Important little known fact is that you do not want to drive aroind with the hubs constantly locked in as you will lower your fuel mileage and cause extra wear to the axles and associated parts. Hope that helps, please come see us again if you have any more questions.
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.
The auto locking hubs are sort of a weak link. Many replace them with manual locking hubs, which last basically forever. Here is a set of instructions: http://npora.ipbhost.com/index.php?showtopic=1405
Do you have automatic locking hubs? Do you need to turn hubs on wheels in order to have 4 wheel drive work? If all you do to get in 4wd is move shifter, then you have automatic locking hubs. The clicking indicates that the hubs are not fully disingaging. To check, block rear wheels, jack front up, and turn tire. the axle should not be turning...if it is, hub is still ingaged....time for new hubs.....if hubs are bad, and you want to save money, you can purchase a set of manual hubs made by (WARN)...its more than half the cost, but you will have to turn hubs to lock and unlock manually. Note...you still need to use the gear selector to put and take out 4wd.
