The short version
- 2004 Jeep Grand Cherokee wheel bearing number for the whole 1999-2004 run: front hub HA598679, a Timken catalog listing.
- One number covers every year and every front corner in this generation. There is no ABS or drivetrain split to check.
- The rear is axle bearing territory. No rear number is documented, so match the old part by the axle tag.
- HA598679 uses Timken’s own numbering rather than the 5-series prefix seen on other Grand Cherokee generations.
Jeep kept the front wheel bearing spec simple on the second-generation Grand Cherokee. A 2004 Jeep Grand Cherokee wheel bearing order at the front is one number, HA598679, covering 1999 through 2004. The rear works differently.
2004 Jeep Grand Cherokee wheel bearing number
A 2004 Jeep Grand Cherokee wheel bearing job at the front needs just this one number.
The rear has no documented number in the catalogs. Match it by the axle tag.

This page covers the 1999-2004 Jeep Grand Cherokee: 1999, 2000, 2001, 2002, 2003, 2004. Other years live on the main Jeep Grand Cherokee wheel bearing page.
HA598679 looks different from most numbers on this site, and that is by design.
It is a Timken catalog listing rather than the 5-series prefix used on other Grand Cherokee generations. The rear stays axle-tag territory, with no documented number to look up at all.
Year by year
Nothing changes across 1999, 2000, 2001, 2002, 2003, or 2004. Every front hub in this generation is HA598679. A 2004 Jeep Grand Cherokee wheel bearing order looks identical to a 1999 or a 2002 one.
The rear never gets a documented number in this generation. Read the axle tag and match the old part, the same approach used on the later years of the 1993-1998 Grand Cherokee.
A different numbering system, a familiar rear rule
Most numbers on this site use a 5-series prefix, but HA598679 comes straight from Timken’s own catalog. The catalogs treat it as the sole listing for this generation’s front hub.
The rear stays true to the pattern set by the earlier truck. The 1993-1998 Grand Cherokee also leaves its rear to the axle tag past the first year, detailed on the 1993-1998 Grand Cherokee page, and the same idea is explained more broadly on the difference between axle bearings and wheel bearings.
That changes with the next redesign. The 2005-2010 Grand Cherokee finally documents a bolt-on rear hub, covered on the 2005-2010 Grand Cherokee page.
Diagnosing a 1999-2004 Jeep Grand Cherokee wheel bearing
- Listen for noise that builds with speed. A worn front bearing tends to get louder as the truck speeds up. It can also shift pitch through a turn, covered on this page about wheel bearing noise in turns.
- Check for play at the wheel. With the wheel off the ground, rock it at 12 and 6 o’clock. Looseness there points at the bearing rather than a suspension part.
- Rule out the tire first. Cupped or uneven tread can sound like a bearing, and this comparison walks through telling the two apart.
- Read the axle tag before ordering a rear part. With no documented rear number, the tag and the old part are the only reliable guide.
- Confirm the front part before ordering. Use this inspection walkthrough to check the worn hub against HA598679 before it gets replaced.

Is there a rear hub bearing on this generation?
No documented one. The rear is axle bearing territory here, identified by the axle tag rather than a hub part number.
