The KYB SM5203 front strut mount replaces that aging bearing and rubber isolator assembly with a direct fit unit designed to restore smooth strut rotation and quiet operation. It's built to the same fitment and durability standards KYB applies across its shock and strut mount lineup, giving you a straightforward way to eliminate one of the more common noise complaints on these trucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDirect fit front strut mount replacement for the QX4 and

vehicle manufacturers, and applies the same engineering discipline to its aftermarket mount and bearing assemblies used in daily driven trucks and SUVs.\u003c\/p\u003e\n\u003ch4\u003eFAQ\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the KYB SM5203?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt's a front strut mount and bearing assembly built by KYB as a direct fit replacement for the 1997 through 2003 Infiniti QX4 and 1996 through 2004 Nissan Pathfinder, designed to restore smooth strut rotation and quiet operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this mount sold individually or as a pair?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe SM5203 is sold individually, so two are needed to service both front strut mounts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace both front strut mounts at the same time?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eReplacing both front mounts together is generally recommended since wear tends to be similar on both sides and it helps keep steering feel balanced left to right.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat symptoms suggest my strut mount needs replacement?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCommon signs include clunking noises over bumps or during turns, stiff or uneven steering wheel return after a turn, and a knocking sensation felt through the steering wheel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill I need an alignment after replacing this mount?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA basic alignment check is recommended any time front strut components are removed and reinstalled, since ride height and mounting angles can shift slightly during the repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit both 2WD and 4WD QX4 or Pathfinder models?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis strut mount is designed for the front suspension shared across QX4 and Pathfinder trims of the covered model years, but always confirm your specific configuration before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat tools are needed to install this mount?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA spring compressor is typically required to safely disassemble the strut assembly, along with basic hand tools and a way to support the vehicle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs there a warranty on this strut mount?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eKYB backs its suspension components with a manufacturer warranty against defects in material and workmanship, consistent with its broader shock, strut, and mount lineup.\u003c\/p\u003e\n\u003ch4\u003eInstall
