Front Suspension Overview, Key Facts, and Polyurethane Upgrade Options
The second-generation Toyota Tacoma (USA), produced from September 2004 through August 2015, is widely regarded as one of the most durable and versatile midsize pickup trucks ever built. Available in multiple chassis and drivetrain configurations, these Tacomas earned a reputation for reliability, off-road capability, and long service life—often exceeding 300,000 miles with proper maintenance.
This article focuses on Tacoma models and front suspension variants commonly found across the following chassis codes:
Covered Models & Front Suspension Variants
- TRN245L (2004.09– )
- TRN265L (2004.09– )
- TRN260L (2004.09–2010.06)
- TRN240L (2004.09–2014.08)
- GRN245L (2004.09–2015.08)
- GRN250L (2004.09–2015.08)
- GRN265L (2004.09–2015.08)
- GRN270L (2004.09–2015.08)
These platforms include both 2.7L inline-4 (TRN) and 4.0L V6 (GRN) powertrains, offered in 2WD and 4WD configurations, regular, access, and double cab bodies.
Front Suspension Design & Characteristics
All Tacoma models listed above utilize an independent front suspension (IFS) with a double wishbone layout, designed to balance ride comfort, durability, and off-road performance.
Key Front Suspension Components
- Upper Control Arms (UCA)
- Lower Control Arms (LCA) – front and rear mounting points
- Coilover shock/strut assemblies
- Stabilizer (sway) bar with end links
- Steering knuckle and ball joints
The control arms play a critical role in maintaining wheel alignment, absorbing road impacts, and controlling suspension geometry under braking, cornering, and load.
Common Wear Points & Maintenance Considerations
Even though the Tacoma is exceptionally robust, front suspension bushings are consumable components. Over time, factory rubber bushings deteriorate due to:
- Heat cycles and UV exposure
- Oil, road salt, and environmental contaminants
- Off-road use and heavy payloads
- Repeated suspension articulation
Typical Symptoms of Worn Front Suspension Bushings
- Clunking or knocking over bumps
- Loose or vague steering feel
- Vehicle wandering at highway speeds
- Uneven tire wear
- Alignment that will not hold
Regular inspection of control arm bushings—especially on lifted or off-road-driven Tacomas—is essential to maintaining proper handling and safety.
Polyurethane Front Suspension Bushing Solutions We Offer
To restore precision and significantly extend service life, we offer polyurethane (PU) replacement bushings for Tacoma front suspension control arms:
- PART #: 1-06-1416
Polyurethane bushing, front suspension, upper control arm
Quantity: 4 per vehicle - PART #: 1-06-1434
Polyurethane bushing, front suspension, lower control arm – front position
Quantity: 2 per vehicle - PART #: 1-06-1433
Polyurethane bushing, front suspension, lower control arm – rear position
Quantity: 2 per vehicle
These components are engineered specifically for Tacoma suspension geometry and load characteristics.
Polyurethane vs. Rubber: Why Upgrade?
Compared to OEM rubber bushings, polyurethane offers clear technical advantages:
- Extended service life – PU resists oil, chemicals, heat, and abrasion far better than rubber
- Improved suspension stability – Reduced deflection keeps alignment consistent under load
- Sharper steering response – Less flex means more precise feedback
- Ideal for lifted and off-road trucks – Handles increased angles and forces without premature failure
- Cost-effective long-term solution – Fewer replacements over the life of the vehicle
Important note: Polyurethane bushings are firmer than rubber. This may slightly increase road feel or vibration, but most Tacoma owners consider the trade-off well worth the improved control and durability—especially for work, towing, and off-road use.
Installation Best Practices
- Always verify fitment by chassis code or VIN before installation
- Completely remove old rubber residue from control arm housings
- Use silicone-based grease on PU bushings during installation
- Press bushings using proper tools to avoid deformation
- Perform a wheel alignment after suspension work
Conclusion
The 2004–2015 Toyota Tacoma remains a benchmark for reliability, but even the toughest trucks benefit from smart upgrades. Replacing worn rubber control arm bushings with polyurethane alternatives restores handling, improves durability, and prepares your Tacoma for years of continued service—on-road or off.
