Car behaves like tires are flat when turning after driving several miles. Front diff works fine on jackstands when cold.

ARE YOU DRIVING IN 2WD WHEN THIS OCCURS?

INSURE THAT EVEN THOUGH EVERYTHING POINTS TO "2WD"

YOUR HUBS ARE NOT LOCKED (EVEN ONE OF THEM)

YOU ARE NOT "REALLY" STILL ENGAGED IN 4X4

YOUR SYMPTOMS ARE LIKE THAT---THIS IS USUALLY THE WAY PEOPLE TELL---IT CONTINUES TO DISPLAY 4X4 DRIVING CHARACTERISTICS

There are no wheel hubs on the 98 explorer its a clutch in the transfer case. I did put the car in 4WD while it was having the problem. It behaved differently and exhibited the characteristic windup/release behavior of 4WD on pavement.

SORTA WINGING THIS

IMMA JEEP CJ KINDA GUY---I UNDERSTAND 4WD, NEW STUFF A BIT DIFFERNT

I HAVE ACCESS TO "MITCHELL 1"---I DO NEED ALL NOMENCLATURE OF THE TRUCK, ENGINE, AND SOME COMPONENTS TO FIND THE CORRECT INFO FOR YOU----"MIT I" IS SORTA COMPLICATED TOO, SO PLEASE BEAR WITH A RURAL RAISED DIYer!

DO YOU HAVE "TRA-LOK"? MANY PEOPLE HAVE NO CLUE WHETHER THEY HAVE LIMITED SLIP DIFFs

IN A JEEP CJ---YOU MUST USE AN ADDITIVE IN WITH YOUR DIFF JUICE TO LUBRICATE THE CLUTCH PACKS

THIS IS A CRITICAL THING TO DO, OTHERWISE THE CLUTCH PACKS WEAR VERY FAST AND YOUR YOKE (PINION) WILL HAVE BIG-TIME PLAY CW AND CCW. I CAN FEEL/ HEAR IT JUST GOING FROM FWD TO REV. ACTUAL HANDS ON, WILL MAKE YOU WANNA CRY IF IT'S GONE ON TOO LONG!

IF YOU HAVE NO CLUE, I FOUND A DIAGRAM IN M1---THIS WILL HELP YOU IDENTIFY WHAT YOU HAVE FOR A FRT AXLE---SEND ALL NOMENCLATURE NEXT RESPONSE

(THIS INFO SHOULD BE OBTAINED WHEN YOU ASK YOUR QUESTIONS, IT WOULD LET US KNOW UP FRONT, WITHOUT US ASKING! MAYBE THEY WILL INCORPORATE IT BACK IN)

I don't know what mitchell 1 is. I am fairly sure the front diff is not limited slip. The rear diff is LS and does require additive. Perhaps to restate the original question I should ask what would the behavior of a locked front diff be on pavement when turning the front wheels. If more information would help I will have to go crawling again.

Have you checked CV joints and u-joints? Also, when it is warm and does this, have you been able to check if the front axle is engaged?

I would have expected clicking noise and not a warm up issue if it were the CV joints. I would be happy if that's what the problem is. Is there a reasonably simple test?

The front axle stays engaged since there are no wheel hubs. Since the car behaves differently when I do put it in 4WD I assume that the clutch in the transfer case is not engaged but I can't rule out some sort of partial engagement.

Hi rivermikerat,

The explorer is not fixed yet. It has been sitting except for a few one mile drives on which it is fine.I have not had it scanned as it seemes hard to imagine the problem as being within the range of what the computer could monitor.

In looking in our reference, I noticed their appears to be a transmission control module and one for the transfer case. I'm seeing a number of DTCs that would or could apply in this case.
BOO shorted or open to ground.
BOO shorted to power.
4WD Hi indicator shorted to ground or power.
4WD Lo indicator shorted to ground or power.
Select switch shorted to ground or power.
T/C Lo to Hi shift relay coil shorted
4WD clutch relay open/shorted to power or ground-Seemingly most likely-causes improper operation.

And on.

(1) See TESTING section.
(2) Clear codes and retest system. If DTC B1342 is still present, replace GEM.
CLEARING DIAGNOSTIC TROUBLE CODES

1.
Connect New Generation Star (NGS) scan tester on Data Link Connector (DLC) and perform proper hook-up. See EQUIPMENT HOOK-UP.
Turn ignition switch to ON position unless otherwise instructed by specified test procedure. Rotate dial on scan tester to DIAGNOSTIC DATA LINK menu and press trigger.
Rotate dial on scan tester to highlight the desired module you wish to access. Ensure DIAGNOSTIC TEST MODES is highlighted and press trigger.
Rotate dial on scan tester to highlight RETRIEVE/CLEAR CONTINUOUS DTC and press trigger. Press button No. 3 to start.
To clear an individual DTC from a selected module, rotate dial on scan tool to highlight the DTC to be cleared. Press button No. 8. This will clear only that DTC from that module.
To clear all DTCs from a selected module, press button No. 7. This clears all DTCs from that module. After DTCs are cleared from ABS control module, turn ignition switch to OFF position
and then back to the RUN position.

RETRIEVING PARAMETER IDENTIFICATION (PID) INFORMATION

NOTE:
This procedure may be used to verify operation of inputs and outputs for
a selected module.
1.
Connect New Generation Star (NGS) scan tester on Data Link Connector (DLC) and perform proper hook-up. See EQUIPMENT HOOK-UP.
NOTE:
If instructed to retrieve PID from a specified test procedure, ensure
ignition switch is in proper position as listed in test procedure. GEM
requires ignition switch to be in ON position or the test will fail.
2.
Turn ignition switch to ON position unless otherwise instructed by specified test procedure. Rotate dial on scan tester to DIAGNOSTIC DATA LINK menu and press trigger.
Rotate dial on scan tester to highlight the desired module you wish to access and press trigger. Rotate dial on scan tester to PID/DATA MONITOR AND RECORD and press trigger.
Rotate dial on scan tester to highlight the PID acronyms you wish to view and press trigger. Repeat this procedure until all desired PIDs are selected. When all PID acronyms have been
selected, press 7 button to view all selected PIDs.

Thanks Rivermikerat,
This is a deluge of information that looks like much repetition but I do see that there are several distinct codes related to functions in an area in which I never realized how many sensors there were. If somehow the vehicle were partially engaging 4WD after warming up that would seem a possible explanation for the symptoms. I did put it in 4WD while it was acting up though and it behaved differently. Nonetheless I will get it scanned.
