The short version
- A 2006 Lexus GS300 wheel bearing at the front is handed: HA590137 for the right side and HA590138 for the left side.
- These same two front numbers cover the GS300 through the V8 GS460. The badge on the trunk does not change the part.
- The rear position is not documented as a single listing: run the VIN.
- All four model years, 2006 through 2009, use the same handed front numbers.
Lexus sold the GS sedan from 2006 through 2009 across several engine badges. The front wheel bearing on every one of them is handed, not universal.
A 2006 Lexus GS300 wheel bearing on the right side is HA590137. The left side is a completely separate number, HA590138.
The core numbers
The right front hub unit is HA590137. The left front hub unit is HA590138, for every GS300 through GS460 built in this range.
The rear runs through the vehicle’s own listings, matched by VIN, across all four model years.

This page covers the 2006-2009 Lexus GS300: 2006, 2007, 2008, 2009. Other years live on the main Lexus GS300 wheel bearing page.
A 2006 Lexus GS300 wheel bearing front hub is handed with separate SKUs per side. Name the side, right or left, before ordering either HA590137 or HA590138.
These listings span the GS300 through the GS460 badge. The front hardware did not change across those engine variants.
The rear has no single documented listing for this generation. Run the VIN against the catalogs instead.
Year by year
2006, 2007, 2008, and 2009 all use the same handed front numbers, HA590137 on the right and HA590138 on the left. Nothing shifts by year on the front. The rear stays VIN territory for the whole span as well.
Why the badge does not change the front number
Lexus sold this generation under several names depending on engine, from GS300 up through GS460. The front suspension hardware carried over across those badges. A 2006 Lexus GS300 wheel bearing on the right side is the same part as the right side hub on a GS460 built the same years.
Confirming the side matters more here than confirming the exact trim, see how to check a wheel bearing.
Diagnosing a Lexus GS300 wheel bearing
- Identify the side first. Right and left front hub units on this car carry separate numbers, HA590137 and HA590138.
- Listen for direction. Front bearing noise on this sedan often changes pitch in a turn away from the bad side, see wheel bearing noise when turning.
- Check for an ABS connection. These front hub units carry the wheel speed sensor, see hub assembly ABS sensor.
- Feel for play at the wheel. Jack up the corner and rock the tire top to bottom to check for looseness in the hub.
- Run the VIN for a rear repair. That position needs the VIN matched against the catalogs, not one universal number.
