The short version
- The 1998-2005 GMC Jimmy splits its front hub by drive type: 513124 for 4WD, and the Timken SP450300 hub with sensor kit SK450300 for 2WD, the core of any 2000 GMC Jimmy wheel bearing job.
- The rear runs axle bearing 5707 every single year, no exceptions.
- Rear seals are chosen by axle code, not by model year: 8660S for code K, 710166 for code C.
- Nothing on this truck’s wheel bearing lineup changes across all eight model years from 1998 to 2005.
Drive type, not model year, decides the front hub on a 1998-2005 GMC Jimmy. A 2000 GMC Jimmy wheel bearing order starts with one question: 4WD or 2WD. Everything downstream of that answer stays fixed across all eight years.
The core numbers
4WD trucks bolt on hub assembly 513124 at each front corner. 2WD trucks use the Timken hub SP450300 instead, paired with a separate SK450300 sensor kit for the ABS ring.
The rear axle bearing is 5707 across the entire 1998-2005 GMC Jimmy run, with the seal behind it chosen by axle code rather than year.

This page covers the 1998-2005 GMC Jimmy: 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005. Other years live on the main GMC Jimmy wheel bearing page.
The 2WD front hub is a Timken SKU, SP450300, and it does not include the ABS sensor. That comes separately as kit SK450300, and skipping it leaves the front corner only half finished.
The rear is axle bearing territory, not a wheel bearing hub, and the seal behind bearing 5707 is chosen by the axle code stamped on the axle tag, not by the model year. See axle bearing vs wheel bearing and drive type and wheel bearings before ordering.
Year by year
1998 through 2005 the front hub lineup does not move. A 4WD 2000 GMC Jimmy wheel bearing order is 513124 for every one of those eight years, and a 2WD truck from the same span takes the Timken SP450300 hub with its SK450300 sensor kit.
The rear side of a 1998-2005 GMC Jimmy is just as flat: bearing 5707 carries every year in the range. The only decision left is the seal, and that comes from the axle code, not the calendar.
Front hub tracks drive type, not trim level
Nothing in the Jimmy’s wheel bearing lineup tracks trim, engine, or option package. It tracks drive type at the front and axle code at the rear, unusual on a body style that otherwise offered SLE and SLS trims through the run.
That makes a 2000 GMC Jimmy wheel bearing order easy to get wrong at a parts counter that guesses by year alone. Confirm 4WD or 2WD before touching the front, and read the axle tag before touching the rear seal.
The ABS sensor kit also matters for anyone chasing a warning light after a 2WD front hub swap, since a mismatched kit is a common cause. See hub assembly and ABS sensors.
Diagnosing a GMC Jimmy wheel bearing
- Confirm drive type first. A 4WD front takes 513124, a 2WD front takes the Timken SP450300 and its sensor kit.
- Listen for the speed linked growl. A worn front hub gets louder as road speed climbs and often shifts pitch in a turn, covered on wheel bearing noise in turns.
- Rule out the tires before condemning the hub. Cupped or uneven tire wear mimics bearing growl; see tire noise or wheel bearing for the difference.
- Check for play with the wheel off the ground. Grab the tire at twelve and six and rock it. Looseness points at 513124 or SP450300, depending on drive type.
- Read the axle tag before the rear seal order. The code stamped there, not the model year, decides between 710166 and 8660S.
Common questions
What wheel bearing does a 2000 GMC Jimmy use?
A 4WD 2000 GMC Jimmy wheel bearing job uses front hub 513124. A 2WD 2000 truck uses the Timken SP450300 hub with the separate SK450300 sensor kit. The rear axle bearing is 5707 either way.
What wheel bearing does a 2005 GMC Jimmy use?
The 2005 GMC Jimmy carries the exact same lineup as 2000: 513124 front for 4WD, SP450300 with SK450300 for 2WD, and 5707 at the rear. Nothing changed across the run.
Is the front hub bolt on or press fit?
Both front hubs, 513124 and SP450300, are bolt on hub assemblies. The rear is a different animal, an axle bearing rather than a hub, behind a seal chosen by axle code.
How do I know if my Jimmy has axle code K or C?
The axle code is stamped on the axle tag on the housing. Code K trucks, sold in Canada, take seal 8660S, and code C trucks, sold in the USA, take 710166.
Does the 2WD front sensor kit come with the hub?
No. SP450300 is the hub alone, and SK450300 is a separate sensor kit. Order both for a complete 2WD front repair.
