93 dodge 3.9 will drive then tires lock - Dodge Cars & Trucks

Check the two vacuum hoses on the right
front side, of the front axle housing

You can use a hand held vacuum gauge, to check
the vacuum modulator & see if it will lock the front axle

Have to have the front end up in air & supported &
turn wheel/tire by hand, as you apply vacuum

Keep in mind with 4 wheel drive,only the right rear &
left front are driven wheels,not all 4

If the front axle locks in, with you pulling a vacuum & you have no
vacuum at the front hoses,then go to the transfer shifter & next to
it,is the vacuum switch

easy way to tell have someone watch the tires as you do a burn out if one tire spins and the other dont then its not locked if both spin then its locked have fun.

1. jack up car
2. place a stand under car
3. remove tire ( have a friens stand on breaks )
4. now remove caliper usually 2 bolts on rear of caliper
5. break pads normally are 3/4 - 1 inch thick new

ok now if you are un sure at anny point in the directions or locating bolts (STOP) go no further
replace tire tighten nuts up and go to a mechanic
it might cost a bit but the alternative is a posability and your life or the life of a family of four is worth more than a few bucks

Yes the front wheels will spin the front shaft but the shaft is not engaged until 4 wheel drive is engaged.

yes unless you changed the tires to a non stock size.

A Dodge Dakota with 4-wheel steer? Do you happen to mean 4-wheel drive?

If so, you should not operate the vehicle in 4-wheel drive when you are traveling on a hard, high-traction surface. When in 4x4, the transfer case connects the front and rear axles, and does not allow for differentiation of wheel speeds necessary when turning. This is compensated for when driving over low-traction terrain because the tires slip easier.

Basically, the jerking, bucking and locking of the truck is due to the binding. This will eventually lead to damage in the driveline. If the roadway isn't covered in snow, there is no need for the 4 wheel drive to be engaged.

on some it goes from motor to firewall or motor to the frame.. you have to have a good eye for it is easily overlooked...good luck

ENSURE THE AIR PRESSURE IN ALL 4 TIRES ARE THE SAME. CHRYSLER UNWITTINGLY HAS A TPMS (Tire Pressure Monitor System) by having an ABS light.
When 1 tire turns slower (or faster) than the other 3, the ABS lamp illuminates when it thinks the wheels aren't turning the same speed, (they aren't). When properly inflated, (or all 4 at least at the same pressure, the ABS Lamp will go out soon, (not immediately). Maybe on the next drive cycle.

A very common problem is faulty tires or incorrect wheel balance of the front tires. Check for a bulge or a wear on the tires. If all is in fine find a mechanic to check your wheel bearings. Check for a broken strut assembly or shock absorber. Check for tire rod bushings and the balance rod. Check complete front suspension.

1998 dodge ram quad..front end wont lock in or the lights come on to tell you its in 4x4..***** little
