The short version
- The LS430 wheel bearing pair for 2001 to 2006: a sealed front hub unit and the 512205 rear.
- The front is listed as 513163 by National and HA593550 by Timken, the same application in two numbering systems.
- This is one of the quietest cars ever built, which hides a failing bearing longer than usual.
- Both ends are their own listings; nothing borrows from the LS400 before it.
Lexus engineered the LS430 to be silent, and that works against you here. A bearing hum that would be obvious in a Corolla stays buried under this car’s insulation until it is well advanced.
The two-name front
The front LS430 wheel bearing appears as 513163 in National’s catalog and HA593550 in Timken’s for the same 2001 to 2006 application.
Different brand numbering, not different hardware: match either and the application lines agree.

The silence problem
By the time an LS430 cabin lets a bearing drone through, the bearing has usually been failing for a while.
Take a faint hum seriously in this car and test early, per the checking page.
Not the LS400, not the LS460
The predecessor LS400 ran press-in ball bearings up front, and the LS460 after moved to handed hub units, so neither neighbor shares this chart. Search by generation, not by the LS badge.
The make overview is on the Lexus page.
High miles, gentle lives
Most LS430s cruise highways and pass 200,000 miles, which is exactly the duty that eventually wears bearings the slow way. A weave test on the tire noise page separates aged tires from an aged hub.
Diagnosing an LS430 wheel bearing
- Trust faint sounds; this cabin muffles everything.
- Weave at speed and place the hum.
- Rock each wheel at twelve and six.
- Match either catalog number; they agree.
- Confirm the generation before ordering.
Cornering behavior is on the noise when turning page.
Common questions
Which LS430 wheel bearing fits the front?
513163, which Timken lists as HA593550. Same application, 2001 to 2006.
And the rear?
512205 for the same years.
Do LS400 parts fit?
No. The older car used press-in front balls; nothing carries over.
Do I need a press?
No. Both ends are hub-unit swaps on this generation.
Why two numbers for one front part?
Catalog brands number independently. The applications match; the hardware is equivalent.
