Front Right Lower Ball Joint for 1998-2010 Lexus GS/SC - TRQ fit

In this review the TRQ front right lower ball joint is assessed as a direct replacement for late 1990s and 2000s Lexus GS and SC models; it is aimed at DIY mechanics and independent shops that need a reliable, pre-assembled suspension pivot. The bottom line: this ball joint gives a convincing direct-fit option with clear compatibility for 1998-2005 GS300, 1998-2000 GS400, 2001-2005 GS430 and 2002-2010 SC430, and its main selling point is ease of installation paired with TRQ's focus on compatibility and DIY video support.

Key Features

• Direct fit replacement: Built as a bolt-in unit to match OE mounting points so installers can expect precise alignment without modification.
• Pre-assembled design: Comes ready to install which saves time and eliminates the need to transfer parts or press components together.
• Dust boot included: The included dust boot helps protect the joint surface from road contamination and extend service life.
• Compatibility guidance: Reference numbers like K500101 and MS86502 are provided to confirm correct fitment for specified Lexus models and years.
• DIY support resources: TRQ positions the part with accompanying instructional videos to help technicians and owners view the repair before they do it.

Who It's For

This ball joint is best for owners and independent mechanics working on compatible Lexus GS300, GS400, GS430 and SC430 cars who want a direct-fit replacement that reduces shop time. It suits DIYers comfortable with basic suspension work who value having access to a reference video and clear reference numbers for cross-checking fitment.

It is not aimed at restorers seeking OE-branded factory parts or at buyers who require a greaseable/adjustable joint; the unit is non-adjustable and not designed for re-lubrication in service, so those needing a serviceable grease fitting should look for a different variant.
