Replace the speed sensor in the transmission this issue has caused rear differential damage on vehicles I have heard of, also check the under neath electrical connections that go to the transfer case to ensure no damage to the wiring harness or electrical plugs has occured

1994 astro van does it have to be drove in overdrive

I would say it could. Especially for in town driving. It would help with the "searching for the right gear" that sometimes occurs at less than highway/open road speeds.

Also for any towing or heavier loads I would recommend NOT using overdrive.

For open road/highway I would use overdrive to get better MPGs.

Hope this helps.

2000 chevy blazer passenger front wheel noise

driving in 4wd on hard surfaces produces what is known as torque wind up as the wheels cannot slip so the variations of distance going around corners , dips in the road etc place considerable strain on the transmission , transfer case , drive lines and diffs
that is why it is difficult to get out of 4wd unless you drive with 2 wheels on a grass verge to relieve that torque wind up
as for the noise check wheel bearings and the cv ("U") joint at that wheel as there appears a proble where the dog teeth in the hub are not engaging properly or are jumping out of engagement

the vdc off can result because the steering input sensor needs to be re calibrated with the nissan consult2 .
the vehicle dynamic control uses input from the abs,vehicle speed sensor,air bag sensor,yaw sensor and steering angle input sensor.

06 F150 4 four wheel drive wont work

I have a 1994 ford f150, my 4 wheel drive keeps trying to engage by itself even without me touching the automatic hub time you can even hear it engaging and disengaging by itself, the low range light even comes on (dimly)...what could be the cause? the transfer case motor looks good and so does the wiring.
