TCM TERMINAL VOLTAGE TESTS
Turn ignition switch to ON position. Access TCM. TCM is mounted under left corner of dash, above fuse box.
DO NOT disconnect harness connector. Using DVOM, measure voltage. See Fig. 4
for terminal identification.
See Fig. 10
and Fig. 11 . After verifying that appropriate condition has been met, check voltage. If voltage is
not within specification, inspect component or appropriate circuit. If voltage is within specification, replace
TCM.

1997-2001 DRIVE AXLES
Axle Shafts - MX-5 Miata
TROUBLE SHOOTING
Inspect CV joint boot on axle shaft for cracks, damage, leaking, grease, and looseness in boot band. Inspect axle
shaft for bending, cracks, and wear of joint splines. Repair or replace as necessary.
REMOVAL & INSTALLATION
AXLE SHAFTS
Removal
1. Raise vehicle and support with safety stands. Remove wheel and tire assembly. Remove axle shaft lock
nut. See Fig. 1
.
2. Remove brake caliper assembly. Remove lower control arm bolt at knuckle, and pull knuckle/hub
assembly outward. Using pry bar between differential housing and inner CV joint, remove inner CV joint
from differential. See Fig. 2
. Remove axle shaft from knuckle/hub assembly. NOTE: See DRIVE AXLE NOISE DIAGNOSIS article in GENERAL INFORMATION.
CAUTION: If vehicle is equipped with ABS, before performing following procedure,
remove ABS wheel speed sensor (axle side) and fix it to an appropriate
place where sensor will not be pulled by mistake while servicing vehicle.
NOTE: If axle shaft will not come out of rear hub support easily, install a discarded nut
onto axle shaft so that nut is flush with end of axle shaft. Tap nut with a copper
hammer to loosen axle shaft from wheel hub.
