1998 Jeep Cherokee Base Lug Nut Torque & Bolt Specs

The 1998 Jeep Cherokee Base lug nut torque is 100 ft-lbs, tightened with a 21mm socket on M14x1.5 studs. Torque in a star pattern in two passes (snug, then final), and re-check after the first 50–100 miles of driving. Use a calibrated torque wrench — not an impact gun — for the final pass.

Lug nut torque: 100 ft-lbs · Socket size: 21mm · Thread: M14x1.5.

This page is the OEM-referenced fastener summary for the 1998 Jeep Cherokee Base. Use it before any maintenance or repair job where torque values matter — brake work, wheel changes, suspension service, engine teardowns, or oil changes. Specs are pulled from manufacturer service literature, cross-checked against community data, and updated as new chassis variants become available.

Stellantis (Jeep/Ram/Dodge/Chrysler) torque values: Wrangler/Cherokee lug nuts spec 100 ft-lbs (135 Nm), Ram 1500 specs 135 ft-lbs (183 Nm), Ram 2500/3500 specs 160 ft-lbs (217 Nm). Most use a 19mm or 22mm socket with M14x1.5 thread on trucks. The Wrangler's hub-centric ring is critical — do not run hub-piloted wheels without it.

Common fastener categories on the 1998 Jeep Cherokee Base

Wheel / lug nut torque and thread spec (covered above)

Repair guidance for this model year

Heads up for 1998 Jeep Cherokee Base owners: Vehicles this age frequently have seized fasteners due to thread corrosion. Apply penetrating oil (PB Blaster, Kroil) 24 hours before any wrenching, and have a thread chaser on hand. Lug studs are particularly prone to thread damage at this age; if a nut spins on without engaging, the stud is stretched and must be replaced before the wheel goes back on.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly

Frequently asked questions

What is the lug nut torque on a 1998 Jeep Cherokee Base?

The OEM-specified lug-nut torque for the 1998 Jeep Cherokee Base is 100 ft-lbs, using a 21mm socket on M14x1.5 thread studs. Use a calibrated torque wrench in a star pattern, in two passes (50% and 100%), and re-check after 50-100 miles of driving.

What socket size do I need for the 1998 Jeep Cherokee Base lug nuts?

The 1998 Jeep Cherokee Base uses a 21mm socket. A 6-point impact-rated socket is recommended over a 12-point chrome socket — 12-points round off lug nuts under impact-driver use.

Are the 1998 Jeep Cherokee Base fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.
