There are several things that could cause a knock, ranging from a worn crankshaft bearing(s) to a worn water pump.

You can further pinpoint this knock by defining if it occurs occasionally, constantly, just at a specific RPM, or only under a load.

What kind of a knock is it? Hi-pitched or low-pitched?

A more detailed problem description would yield you a more specific/helpful answer.

SOURCE: TPS in a 1998 GMC Jimmy

the tps is ususally at the side of the throttle body opposite where the throttle cable / tv cable mount.
sometimes it won't start, run, or run erratically. there are ways of testing this unit (by output voltage) before you commit to buying a new one. to test it you will need a dvom (digital volt ohm meter).

just a note: straight from the book... "a broken or loose tps can cause intermitten burst of fuel from the injector and an unstable idle because the ecm thinks the throttle is moving."

SOURCE: 98 gmc jimmy front hub

1. Put the vehicle in gear, apply the parking brake and break loose the driveaxle/hub nut with a socket and large breaker bar.
2. Loosen the wheel lug nuts, raise the vehicle and support is securely on lackstands. Remove the wheel. Remove the driveaxle/hub nut.
3. Unbolt the brake caliper and hang it out of the way with wire. Remove the brake disc.
4. On models with four wheel ABS, trace the electrical lead for the wheel speed sensor along the upper control arm, then forward along the frame rail and unplug the electrical connector.
5. Remove the hub assembly-to-steering knuckle bolts. Remove the brake disc shield and wheel speed sensor assembly and set aside.
6. Tap the hub assembly from side-to-side to break it loose from the steering knuckle. Pull the hub assembly off the end of the driveaxle. Wrap the end of the driveaxle with a rag to prevent damaging it. If the hub is stuck on the splines on the end of the driveaxle, use a puller to free it.
7. Installation is reverse of removal process. Be sure to lubricate the driveaxle splines with multi-purpose grease, and tighten all of the fasteners to the proper torque.

SOURCE: How do you get to the heater core in a 98 GMC Jimmy?

THE STEERING COLUMN (DO NOT ROTATE THE STEERING WHEEL AFTER THE INTERMEDIATE SHAFT IS REMOVE, YOU WILL BREAK THE SIR COIL), WINDSHIELD MOLDINGS, AND DASH HAVE TO BE REMOVED FIRST. UNDER THE HOOD THE BLOWER RESISTOR, R/H INNER FENDER WELL, HEATER HOSES TO THE HEATER CORE AND SEVERAL NUTS AND BOLTS HOLDING THE HEATER PLENUM TO THE FIRE WALL INCLUDING THE HIDDEN BOLT UNDER THE BLOWER RESISTOR IN THE EVAPORATOR CORE AREA. THEN FINALLY THE BOLTS ON THE INSIDE OF THE TRUCK HOLDING THE PLENUM TO THE FIREWALL.

NO DISRESPECT INTENDED BUT IF YOUR NOT A TALENTED MECHANIC I WOULD FIND ONE OR HIRE ONE THAT CAN DO THE JOB FOR YOU. THIS IS QUITE INVOLVED FOR A NOVICE.

Knock sensor on 1998 gmc jimmy


it is located beside the crank pully. it controls the timing, a bad one will give you bad fuel mileage and could get a knocking sound when going up step hills. it keeps the engine from knocking by adjusting timing.

Its the same thing except it says GMC on the front. The most common issues with either of them is ABS problems, wheel bearings, ball joints, intake gaskets, plugged heater cores, injector issues, fuel pressure regulators, fuel pumps, catalytic converters, wiper motors, window motors, 4x4 issues, and the list goes on.
