Check the VSS Voltage:
1. Raise the vehicle2. Shift the transmission to lEposrtlon.3. Disconnect the A (26P) and B(22P) connectors from the
TCM.4. Turn the ignition switch ON {ll).
5. Rotate the front wheel and
check for the voltage between
the 85 and 413 or A26 termi-
nals. Block the other wheel so
at does not turn
Check for oP€n in the wire
between the 85 terminal and the
vehicle speed sensor {VSS}. lf
wire is OK, check the vSS (see
soction 23).

Installation (cont'd)
Install I new set ring on the end of each driveshaft.
Install the right and left driveshafts (see section 16).
CAUTION: While instatling the drive3hafts in thedifferential, be sure not to allow dust and olher for-aign particles to enter into tho transmission.
NOTE:
. Clean the areas where the driveshafts contact thetransmission {differential} thoroughly with sol-vent or carburetor cleaner, and drv with com-
Dressed air.
. Turn the right and left steering knuckle fully out-wa.d, and slide each driveshaft into the differen-tial until you feel its set ring clip engage the sidegear.
Install the damper fork, then install the right and leftball joints to each lower arm with the castle outsand new cotter pins.
