Home › Vehicles › Isuzu › Isuzu NPR Wheel Bearing Part Numbers
The short version
- The Isuzu NPR wheel bearing setup is a serviceable tapered cone and cup design at both ends of the truck. It is not a bolt-on hub assembly.
- Front uses inner cone 474230 with cup 32210, plus outer bearing 32207, for 1986 through 1999.
- Rear uses inner seal 710080 with bearing 29586-29520, and outer seal 710081 with bearing 28680-28622, for 1985 through 1999.
- A 2000 or newer NPR is not covered here. Match it by VIN through a commercial truck parts counter.
Isuzu built the NPR as a cab-over workhorse. The wheel end hardware reflects that: hand-serviced tapered bearings instead of a disposable hub unit. That design has stayed in the documented catalogs since the mid-1980s.
The NPR’s cone and cup numbers
The front carries an inner cone, 474230, with cup 32210, plus an outer bearing, 32207. The rear carries an inner seal and bearing plus an outer seal and bearing, each with its own number.
None of these share a single hub part number the way a car’s bolt-on assembly would.

Everything above covers the Isuzu NPR wheel bearing setup for 1985 through 1999 documented production. For a 2000 or newer truck, match by VIN through a commercial truck parts counter.
Isuzu changed the NPR enough after 1999 that guessing from the older cone and cup numbers is not safe.
A serviceable bearing, not a bolt-on hub
The NPR is a medium duty cab-over truck. Its front and rear wheel ends use serviceable tapered cone and cup bearings, not sealed bolt-on hub assemblies. A technician packs and adjusts these by hand instead of bolting in a preassembled unit.
Knowing how to tell a serviceable bearing from a sealed one matters before ordering parts. This is also the first model page under the Isuzu hub on this site.
Commercial duty changes the maintenance math
An NPR hauls loads that a passenger car bearing never sees. The tapered roller design handles that combined radial and thrust load better than a typical ball bearing. Getting preload and end play right matters more here, since a tech sets it by hand.
Fleet shops that run these trucks daily often treat a bearing repack as routine maintenance rather than a repair. The cone and cup design is built to be serviced repeatedly.
Diagnosing an Isuzu NPR wheel bearing
- Listen for a persistent hum or growl at speed. A worn tapered bearing produces a steady tone that builds with road speed.
- Check for play with the wheel jacked up. Grab the tire at 12 and 6 o’clock and rock it. Excess play usually means it needs repacking or replacing.
- Pull the hub and inspect the grease. Contaminated or gritty grease is often the first sign of a failing seal.
- Inspect the cone and cup surfaces directly. Pitting or flat spots on the rollers mean the bearing needs replacing, not just repacking.
- Recheck preload and end play after service. A bearing set too tight or too loose will fail again quickly, even with good parts.
Common questions
What is the front Isuzu NPR wheel bearing part number?
The front uses a serviceable tapered set: inner cone 474230 with cup 32210, and an outer bearing, 32207. These cover 1986 through 1999 documented production.
What is the rear Isuzu NPR wheel bearing setup?
The rear uses an inner seal, 710080, with bearing 29586-29520, and an outer seal, 710081, with bearing 28680-28622. These cover 1985 through 1999.
Is the NPR wheel bearing a bolt-on hub assembly?
No. It is a serviceable tapered cone and cup setup that gets packed and adjusted by hand, not a sealed cartridge that bolts on as a unit.
Do these numbers work on a 2000 or newer NPR?
Not reliably. Match a 2000 or later NPR by VIN through a commercial truck parts counter.
How often should an Isuzu NPR wheel bearing be repacked?
The catalogs do not set a fixed interval, and duty cycle varies too much on a commercial truck. Treat it as routine maintenance and inspect the grease whenever the wheel end is opened.
