  Suspension Ball Joint, Joint Assembly Lower Ball

• Description:

  Restore factory-spec handling, precise tracking, and structural safety to your truck or SUV with the Genuine Toyota 43340-39445 Front Left Lower Ball Joint Assembly. As a primary load-bearing pivot point in your vehicle's front suspension system, the lower ball joint bears massive dynamic forces by connecting the wheel hub assembly directly to the lower control arm.

  Vehicle Compatibility

  This genuine replacement part is engineered specifically for the front driver side (LH) on 2WD / 5-Lug / Non-PreRunner models only:

  • Toyota Tacoma (2WD / 5-Lug / Non-PreRunner): 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004
  • Toyota 4Runner (2WD Non-PreRunner models): 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002

  (⚠️ Fitment Warning: This part will not fit 4WD or PreRunner 6-lug models. This SKU officially replaces older legacy part number 43340-39275.)

   

  Because 1st Generation Tacoma and 3rd Generation 4Runner feature a suspension configuration where the ball joint is under constant tension, maintaining a healthy component is vital to preventing catastrophic failure. Over time, internal ball-and-socket wear leads to loose tolerances. Common warning signs include an annoying squeak or creak while turning at slow speeds, harsh metallic clunking when driving over speed bumps, or a dangerous steering "wander" on the highway. Replacing your worn factory unit with this all-in-one genuine assembly eliminates loose steering play and guarantees safe structural alignment.

  Key Features

  • All-In-One Assembly: Includes the heavy-duty lower ball joint integrated directly into the factory steering knuckle arm for a streamlined installation.
  • Precision Geometry: Manufactured to match original engineering tolerances, ensuring your wheels align perfectly without suspension modifications.
  • Premium Dust Boot: Sealed with a high-grade synthetic rubber boot designed to lock out abrasive road grime, salt, and water while retaining lifetime factory grease.
  • Maximum Tensile Strength: Constructed from forged alloy steel to handle extreme vertical and lateral loads without flexing.
  • Complete Install Hardware: Ships with necessary replacement hardware, including a fresh castle nut and cotter pin for a secure finish.

  Why Choose Factory OEM Over Aftermarket Brands?

  Suspension components are critical safety items. Many universal aftermarket ball joints compromise by using loose internal tolerances or cheap boot materials that split within a few thousand miles, exposing the dry joint to dirt and moisture. A genuine factory component guarantees identical steel density, correct taper layout, and crash-tested structural reliability that keeps your vehicle tracking straight for years to come.
