there is a small round spring clip on the 3/4'' steel shaft almost hiden by metal plate push down on plate with plate pushed down have a trusted friend carefully remove steel spring clip with a small scriber or similar careful not to poke friend with tool good luck with this project
The combination Fuel Filter/Fuel Pressure Regulator is located on the fuel pump module. The fuel pump module is located on top of fuel tank.
The filter/regulator may be removed without removing fuel pump module although fuel tank must be removed.
Remove fuel tank. Refer to Fuel Tank Removal/Installation.
Clean area around filter/regulator.
Disconnect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
Remove retainer clamp from top of filter/regulator. Clamp snaps to tabs on pump module. Discard old clamp.
Pry filter/regulator from top of pump module with 2 screwdrivers. Unit is snapped into module
Discard gasket below filter/regulator.
Before discarding filter/regulator assembly, inspect assembly to verify that O-rings are intact. If the smallest of the two O-rings can not be found on bottom of filter/regulator, it may be necessary to remove it from the fuel inlet passage in fuel pump module.
Clean recessed area in pump module where filter/regulator is to be installed.
Obtain new filter/regulator (two new O-rings should already be installed)
Apply a small amount of clean engine oil to O-rings. Do not install O-rings separately into fuel pump module. They will be damaged when installing filter/regulator.
Install new gasket to top of fuel pump module.
Press new filter/regulator into top of pump module until it snaps into position (a positive click must be heard or felt).
The arrow molded into top of fuel pump module should be pointed towards front of vehicle (12 O'clock position).
Rotate filter/regulator until fuel supply tube (fitting) is pointed towards front of vehicle (12 O'clock position).
Install new retainer clamp (clamp snaps over top of filter/regulator and locks to flanges on pump module).
Connect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
Install fuel tank. Refer to Fuel Tank Removal/Installation.
WARNING: THE FUEL SYSTEM IS UNDER CONSTANT FUEL PRESSURE EVEN WITH THE ENGINE OFF. THIS PRESSURE MUST BE RELEASED BEFORE SERVICING FUEL TANK .
Two different procedures may be used to drain fuel tank (lowering tank or using DRB scan tool).
The quickest draining procedure involves lowering the fuel tank.
As an alternative procedure, the electric fuel pump may be activated allowing tank to be drained at fuel rail connection. Refer to DRB scan tool for fuel pump activation procedures. Before disconnecting fuel line at fuel rail, release fuel pressure. Refer to the Fuel System Pressure Release Procedure for procedures. Attach end of special test hose tool number 6541, 6539, 6631 or 6923 at fuel rail disconnection (tool number will depend on model and/or engine application). Position opposite end of this hose tool to an approved gasoline draining station. Activate fuel pump and drain tank until empty.
If electric fuel pump is not operating, tank must be lowered for fuel draining. Refer to following procedures.
FUEL TANK REMOVAL
Disconnect negative battery cable at battery.
Release fuel system pressure. Refer to the Fuel System Pressure Release.
Raise and support vehicle.
If Equipped: Remove fuel tank skid plate.
Remove 4 fuel hose shield mounting bolts and remove fuel hose shield from body.
Remove fuel tank fill hose and vent hose clamps at fuel tank filler tube. Remove both hoses at fuel filler tube.
Remove exhaust tailpipe heat shield mounting bolts and remove shield. CAUTION: To protect fuel tank from exhaust heat, this shield must reinstalled after tank installation.
Place a hydraulic jack to bottom of fuel tank. WARNING: PLACE A SHOP TOWEL AROUND FUEL LINES TO CATCH ANY EXCESS FUEL .
Disconnect fuel supply line from fuel extension line near front of fuel tank. Refer to Fuel Tubes/Lines/Hoses and Clamps. Also refer to Quick-Connect Fittings for procedures.
Disconnect EVAP canister vent line near front of tank.
Disconnect fuel pump module electrical connector (pigtail harness) near front of tank. Harness connector is clipped to body.
Remove two fuel tank strap nuts. Position both tank support straps away from tank.
Carefully lower right side of tank while feeding both fuel hoses through access hole in body. Fuel Tank Full And Not Drained Using DRB Scan Tool: To prevent fuel loss through hoses, keep left side of tank higher than right side while lowering. Do not allow hose openings to drop lower than top of tank.
Continue lowering tank until clear of vehicle. Place tank on floor with left side (hose side) higher than right side
Drain tank by removing fuel fill hose at tank. Fuel fill hose is largest of 2 hoses. Insert the drain hose (from an approved gasoline draining station) into hose opening. Drain tank until empty.
If fuel pump module removal is necessary, refer to Fuel Pump Module Removal/installation for procedures.
If fuel pump module is being installed, refer to Fuel Pump Module Removal/installation for procedures.
Install fuel fill/vent hoses to tank fittings. To prevent hose from kinking, rotate each hose until index mark on hose is aligned to index tang on fuel tank.
Install hose clamps to hoses. Position clamps between index marks on each hose.
Position fuel tank to hydraulic jack.
Raise tank into position while guiding fuel fill and vent hoses into and through access hole in body.
Continue raising tank until positioned to body.
Attach two fuel tank mounting straps and mounting nuts. Tighten nuts to 10 Nm (90 in. lbs.) torque. Do not over tighten nuts.
Install both fuel hoses to fuel fill tube. Tighten both retaining clamps.
Position fuel hose shield to body. Install and tighten 4 mounting bolts.
Connect fuel pump module pigtail harness electrical connector near front of tank.
Connect fuel pump module supply line near front of tank. Refer to Quick-Connect Fittings for procedures.
The Camshaft Position Sensor (CMP) on the 4.7L V - 8 engine is bolted to the front side of the right cylinder head. Disconnect the sensors connector. Take out the bolt that holds the sensor in place. Lightly pry out the sensor being careful not to break it. Clean out the hole and install the new sensor( put a little oil on the new sensors o-ring to help installation).

A few parts should be interchangeable. Most of them will not be however since the Grand Cherokee underwent a complete re-design for 1999. Some engines and transmissions will switch out. The rear axle in the 97 was commonly a Dana/Spicer 35. This was replaced with a larger rear differential in 1999 for increased towing capacity. The wheels should interchange ok, power steering system was pretty much the same and as long as the hydraulics (supports) on the hood are the same length they should work
The steering wheel has to be removed to do that. Removing the steering wheel requires removing the airbag, which leads to a whole other can of worms. If you've never worked on the airbag system or don't know how to, best to leave it to someone who does or you may end up with a huge repair bill, if you accidentally deploy the airbags.
Part you need is called a clock spring this is a dealer only part
you will need to remove the airbage and steering wheel to do this
Once wheel is off you will need to remove 3 torkx screws to remove the clock spring reverse to install everything
If your not experiencecd in this i recomend taking it to a ase shop
it's inside the steering wheel
must be careful, because of the air bag.
disconnect the battery and wait for 10 minutes for the air bag capacitor to discharge power.
remove the air bag module from the steering wheel
remove the center nut, then steering wheel
the clock pring is a yellow round piece that fitted inside the steering column. there is a snap ring hold the clock spring in place. disconnect the wiring then remove the clock spring.
Changing the heater core requires complete removal of the dash panel
and plenum box. To do this you have to remove the steering wheel,
steering column, evacuate and recharge the refrigerant system and drain
the radiator. I would only consider changing the heater core if it is
physically leaking into the passenger compartment. If the problem is
heat transfer to the HVAC system only, the problem is more likely with
the blend doors. Check heatertreater.net for pictures and diagnostic
Jeeps did have a problem with the clock spring in the steering column.
This clock spring is a part that connects the lower harness with the
switches on the steering wheel. To replace the clock spring it will
have to be done by a qualified tech since the airbag itself has to be
removed. Have the car checked for codes first before making any repairs.
