This page covers the 2001 through 2005 Pontiac Aztek. The front number depends on equipment starting in 2003, but a 2002 Pontiac Aztek wheel bearing front is simple, since every trim shares one number that year. The rear stays undocumented across the whole run.
The core numbers
2001 and 2002 use 513187 for every trim, no exceptions. From 2003, a base FWD car without ABS drops to 513203, while ABS cars and Versatrak AWD cars stay on 513187.
A 2002 Pontiac Aztek wheel bearing order is 513187 regardless of trim, since that split does not apply yet. The rear has no documented number for any year.

This page covers the 2001-2005 Pontiac Aztek: 2001, 2002, 2003, 2004, 2005. Other years live on the main Aztek wheel bearing page.
Starting in 2003, a base FWD car without ABS drops to 513203. Everything else, meaning ABS cars and Versatrak AWD cars, keeps the older 513187 number.
The rear is a genuine gap for the entire 2001 to 2005 run. Match the number the old part carries or confirm fitment by VIN.
Year by year
2001 to 2002: every trim uses 513187 up front. A 2002 Pontiac Aztek wheel bearing order does not need an ABS or AWD check yet, since the split starts the following year.
2003 to 2005: check ABS and drivetrain before ordering. A base FWD car without ABS takes 513203, while ABS cars and Versatrak AWD cars keep 513187.
Across all five years, the rear stays undocumented. Match the old part or run the VIN on the rear regardless of year.
Versatrak AWD and the equipment split
The Aztek’s front hub split by equipment rather than by a clean model year boundary, and it only shows up from 2003 forward. That puts Versatrak AWD cars in the same bucket as ABS equipped FWD cars for drive type purposes on the front hub. A base FWD car without ABS is the only configuration that moves to the newer 513203 number.
Diagnosing a Pontiac Aztek wheel bearing
- Confirm the model year against the 2003 split. 2001 and 2002 need no further check on the front.
- Check ABS and drivetrain on 2003 and later trucks. Only a base FWD car without ABS uses 513203.
- Jack up the front wheel and check for play. The general method at how to check a wheel bearing applies without changes here.
- Listen for a change in a turn. A pattern that grows louder loading one side fits the notes at turning noise notes.
- Pull the old rear hub before ordering a replacement. With no documented rear number, the physical part or the VIN is the only reliable match.
