where is the speedometer gear!!!

my speedometer decided to stop working along with my odometer, cruise control, and over head gauges. the speedometer will randomly come on and then all the other things work to but then it will cut off randomly and everything will stop. my CHL is on and it says the rear speedometer needs to be replaced. i looked on my trans and there was no place for the gear. i asked a local shop and they said it is in the axle and i cant find it there either. is there anyone that might know how to fix this weird problem?

speedometer gears are on the transfer case

Not on WJ's. The WJ's pull their speedo info from the ABS tone rings on the axle shafts.

What is "CHL" in your phrase "my CHL is on"?

WJs don't have a speedometer gear. The PCM in WJs use the wheel speed sensors to generate the speedometer reading.

Edit: Post #4 beat mine, but I will just leave it up.

Since the gauges are acting up, you problem might be electrical and have nothing to do with the wheel speed sensors. In order to go any further more info is needed. Retrieve the trouble codes using the key on/off method. It goes like this,
Quote:
Turn the ignition key until the digital odometer displays, repeat two times in succession and then back to "On" (On/Off, On/Off, On). At the third "On" the odometer reading will be replaced with codes. If no codes are present then "donE" will appear.
The codes will have the form P0xxx and/or Pxxxx. Post any numbers that you get.

After that, disconnect the battery cables, and make sure that the cable connectors and battery terminals are clean and free of corrosion. Disconnecting the battery will usually erase any codes. Start back up and see if the CEL comes back on. Whether it does of not, retrieve (using the above procedure) any codes and post the numbers again.

BTW, you can use the tach displaying engine rpms to get pretty good numbers for the vehicle speed when in 4th gear.

118 is a coolant temp sensor issue unrelated but get it fixed

500 is a no speed sensor signal issue

P0500-NO VEHICLE SPEED SIGNAL
When Monitored: Engine Temperature greater than 104 deg F. , MAP vacuum approximately
159 to 169 inches of mercury and Engine RPM between 1400 and 3000 rpm.
Set Condition: No Vehicle Speed Signal for more than 15 seconds on two consecutive
trips.

Is your abs light on? If not then you have issues with either your wiring between the abs computer and the PCM or the PCM itself.

Here is the troubleshooting guide from the FSM

1 Ignition on, engine not running.
With the DRBIIIt, read DTCs and record the related Freeze Frame data.
NOTE: Any VSS DTCs in the CAB Module or Body Controller must be
properly diagnosed before continuing.
Is the Good Trip Counter displayed and equal to zero?
All
Yes ! Go To 2
No ! Refer to the INTERMITTENT CONDITION Symptom (Diagnostic
Procedure).
Perform POWERTRAIN VERIFICATION TEST VER - 5.
2 Turn the ignition off.
Disconnect the PCM harness connectors.
Disconnect the ABS Control Module harness connector.
Measure the resistance of the (G7) Vehicle Speed Signal circuit between the PCM
harness connector and the ABS Control Module harness connector.
Is the resistance above 5.0 ohms?
All
Yes ! Repair the open in the (G7) Vehicle Speed Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No ! Go To 3
3 Measure the resistance between ground and the (G7) Vehicle Speed Signal circuit at
the PCM harness connector.
Is the resistance below 100 ohms?
All
Yes ! Repair the short to ground in the (G7) Vehicle Speed Signal
circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No ! Go To 4
DRIVEABILITY - GAS
TEST ACTION APPLICABILITY
4 Ignition on, engine not running.
Measure the voltage on the (G7) Vehicle Speed Signal circuit at the PCM harness
connector.
Is the voltage above 4.8 volts?
All
Yes ! Repair the short to voltage in the (G7) Vehicle Speed Signal
circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No ! Go To 5
NOTE: Turn the ignition off before continuing.
5 NOTE: Before continuing, check the PCM harness connectors for corrosion,
damage, or terminal push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
All
Repair
Replace and program the Powertrain Control Module per Service
Information.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

Did you start up the engine before retrieving the codes the 2nd time? Actually, driving it some would be better. If you have no codes and the CEL is not on, you should be good to go.

Have you been in the mud lately. Mud can cake on the tone rings and/or wheel sensors and cause them to give no or erratic signals. If that's not the problem, then it looks like you will have to take it to the dealership so that it can be properly diagnosed. The P0500 doesn't really give enough info.
