Home › Vehicles › GMC › GMC Sonoma Wheel Bearing Part Numbers › 1994-2004 GMC Sonoma Wheel Bearing Part Numbers
The short version
- A 2002 GMC Sonoma wheel bearing number depends on drivetrain. 4WD trucks from 1998 to 2004 use front hub 513124. 2WD trucks use the serviceable SET6 inner bearing, SET34 outer bearing, and seal 4739.
- Earlier 4WD trucks, 1994 to 1997, use a different front hub, 513061.
- The rear runs one bearing, 5707, across the whole 1991 to 2004 span. The seal is chosen by axle build code rather than year.
- 2WD front documentation stops at 2003. A 2004 2WD truck should be matched to the old part or the VIN.
This page covers the 1994 through 2004 GMC Sonoma. Drivetrain splits the front listing into two different kinds of part. A 2002 GMC Sonoma wheel bearing order has to answer that drivetrain question before anything else.
The core numbers
4WD front hubs split by year: 513061 for 1994 to 1997, then 513124 for 1998 to 2004. A 2002 GMC Sonoma wheel bearing on a 4WD truck is always 513124, regardless of trim.
2WD fronts never use a hub assembly. The inner bearing is SET6, the outer bearing is SET34, and the seal is 4739. That listing is documented from 1991 through 2003.

This page covers the 1994-2004 GMC Sonoma: 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004. Other years live on the main Sonoma wheel bearing page.
The 4WD front hub changes at 1998. A 1997 truck and a 1998 truck take different numbers even though they look the same. 2WD fronts never take a hub at all; they stay a serviceable inner bearing, outer bearing, and seal.
The rear seal depends on the axle build code stamped on the truck, not the model year. The 2WD front listing also stops documentation at 2003. A 2004 2WD truck should be matched to the old part or the VIN.
Year by year
1994 to 1997: 4WD trucks use front hub 513061. 2WD trucks already run the SET6, SET34, and 4739 combination. The rear runs 5707 with the seal picked by axle code.
1998 to 2003: 4WD trucks switch to front hub 513124. This is the number behind a 2002 GMC Sonoma wheel bearing order. 2WD trucks keep the same serviceable set, and the rear logic does not change.
2004: 4WD trucks continue on 513124. The 2WD front set has no documented row for this year, so match the old part or run the VIN. The rear bearing 5707 and its seal split still apply.
Serviceable fronts and a solid rear axle
The Sonoma splits its maintenance approach by drive type more sharply than most trucks its age. A 4WD hub is a sealed unit that gets replaced whole. A 2WD front bearing set is packed with grease and its preload adjusted by hand, a job covered at repacking wheel bearings.
The rear is a solid axle design, which puts the 5707 bearing in axle bearing territory. Its seal choice tracks the axle build code, not the calendar.
Diagnosing a GMC Sonoma wheel bearing
- Identify the drivetrain first. A 4WD Sonoma and a 2WD Sonoma need completely different parts and completely different service approaches.
- Check 2WD front play by hand. With the wheel off the ground, grip it and rock it; excessive play in a serviceable set often means it needs repacking or replacement, not just adjustment.
- Listen for a rear growl. A worn 5707 rear bearing tends to produce a steady drone that builds with speed rather than one that changes sharply in turns.
- Read the axle tag before ordering a rear seal. The code on the axle, not the model year, decides between 8660S and 710166.
- Run the general check on any wheel. The steps at how to check a wheel bearing apply the same way to a 4WD hub or a 2WD bearing set.
Common questions
What wheel bearing does a 2002 GMC Sonoma use?
A 2002 GMC Sonoma wheel bearing depends on drivetrain. A 4WD truck uses front hub 513124, and a 2WD truck uses the SET6 inner bearing, SET34 outer bearing, and seal 4739.
What wheel bearing fits a 1996 GMC Sonoma?
A 1996 truck falls in the earlier 4WD window, so a 4WD front hub is 513061. A 2WD truck already runs SET6, SET34, and seal 4739, the same as later years.
Why doesn’t the 2WD front listing cover 2004?
The catalogs document the 2WD front set only through 2003. For a 2004 2WD truck, match the number the old part carries or confirm fitment by VIN.
How do I pick the right Sonoma rear seal?
Read the axle build code stamped on the truck. Code K, a Canada build, takes 8660S, and code C, a USA build, takes 710166.
Is the Sonoma 2WD front bearing a bolt on hub?
No. It stays a serviceable set on every year this page covers: an inner bearing, an outer bearing, and a seal, packed and adjusted rather than bolted on as a unit.
