- Protective glasses
- WD 40, the screws might be rusted
- 3/8" Ratchet, extensions and u-joints
- 10 mm socket and open wrench
1. Place the rear of the car on jacks or use a ramp, then
spray the old sensor two screws with WD40. Now that you have
found where the screws are... you know that removing them
is going to be tricky.
If you are not a patient person, grab your phone and call
2. After approximately 1 hour, you have removed the screws.
Try to clean your sensor, it might work again (it didn't work
for me). If cleaning it does not work, just change the sensor.
3. Tighten the screw with a 10mm open wrench then finish with
the ratchet and extensions.
Best advice : Be patient...

The hard part is getting to the bottom screw, IMO. Having
a heckuva time getting it started after
removal, I decided to do the following:
. support the differential with a hydraulic jack
. remove the two bolts (19mm head) holding the rear of the
diff to the suspension member
. drop the diff about an inch or less
The issue is ensuring that the diff is supported. What dropping
the diff does is give enough room
to get a direct angle on the bolt, both for removal and replacement.
A caveat is to do the removal
and replacement of the top bolt before and after the diff
Also, I found that my 3/8" drive sockets were a tad
thick for the available clearance. I used 1/4"
hardware with a 3/8" to 1/4" adaptor.
Regardless, it certainly is a job that requires patience.

Thought you might want to know, I replaced my speed sensor
and while it was time consuming, it was really not too difficult.
Most of the time was de-greasing and cleaning area first.
I used 1/4" vs 3/8" tools: 10mm open wrench, 1/4"
10mm socket, 1/4" ratchet with 3" and 5" extensions
and "u" joint. and had no problem reaching lower
and upper bolts as follows:
Upper bolt: Socket drive to 5" extension to U joint to
3" extension with 10mm socket: between gas tank shield
and suspension / diff
Lower bolt: Socket drive to 3" extension to U joint with
10mm socket: between suspension and diff
