If you look at this picture, exploded view of front diff , It looks like #16 or #13 could be missing or broken, causing the plunger not to pull out keeping the front end engaged. Looks like it would have to be opened up to replace.

I have a 78 Dodge Ramcharger, 4x4 auto. trans., when in low lock on transfer case (# 203) pulling up out of a creek bed, I heard a fairly loud clunk from the front end, backed-off on the gas a little...


if it has a spring between the side gears , it may be a limited slip diff center and the noise may have been the limited slip action coming off or engaging when one front wheel lost traction
if there is no metal bits in the diff then it may be nothing as long as both wheels turn the diff center , then the axle will still be intact

I just replaced the front diff accuator and it still wont shift into 4x4 i also pulled the fuse to reset it. It sounds like its working but wont shift,the 4x4 light just comes back on any suggestions?


there is an aluminum shift fork behind the actuator that has a knurled end on it.that end breaks off and will not allow the diff to lock in.you will need to remove the passenger side axle and the actuator to access.also check the transfer case shift module.also common on that vehicle.

Chrysler voyager electronic doors doors do not


a common problem with Chrysler/Dodge minivans .. when you open the sliding door you will see two flat brass contacts on the door frame and two spring loaded plungers that connect to the flat brass contacts when the door is closed .. this provides power to the rear door locks when the lock is accuated.. .. i thought the contacts would surely be plated with something but they are not ... if they were plated then you would have to be careful how you clean them . but as it is you can use steel wool or sand paper and a cleaning solvent like alcohol .. clean both contacts and plunger tips .. for reliable operation you have to keep those clean ... in later years they started putting a rolling loop of wire connecting the doors electronics to the cars lock control .. thats probably more reliable .. the danger in the dirty contacts is that you might not know your back doors are unlocked unless you look every time .. and i bet the theves know that also .. ..

Front end will not lock in 4x4


if you crawl under the vehicle, trace vacuum lines to transfer case they terinate in a group of 3 (vent, vacuum from engine, line to actuator diaphram under battery) . Mark lines (bundle should have a pin to prevent bad replacement, but be safe) pop 3 hose unit , unscrew switch (count the turns to return it to same position). Transfer case side has a ball that should detent fairly easily. If stuck, work it loose or replace the switch. This manual detented switchsimply routes vacuum to diaphram which pulls cable to front axle, or vents it to atmosphere when in 2wd.

You should be able to feel if diaphram is pulling in when in 4wd and is relaxed when in 2wd mode to troubleshoot. Direct vaccum to diaphram line to test. I have used aquarium airline tubing and airstone manifold to provide quick fix when a garage and/or access to parts was not available. You want to be able to direct vent to diaphram for 2wd and engine vacuum to diaphram for 4wd.

4x4 on a 2001 s10


when the transfer case shifts into 4wd it activates a vaccum switch on the transfer case which sends vaccum to the accuator for the front axle. the accuator pulls a cable that locks in the axle. the switch on the transfer case is a well known problem. check for vaccum in and out of this switch in 4wd. if you have vaccum out then check the accuator under the battery. If the vaccum switch on the transfer case is bad you can find one at most parts store in the HELP section #49315. please rate if this helps
