TRQ Front Lower Control Arm w/Ball Joint LH Left Driver Side - Direct

In this review of the TRQ Front Lower Control Arm w/Ball Joint LH, the bottom line is simple: this part is for owners of late 1999-2006 Chevrolet and GMC full-size trucks and SUVs who need an affordable, direct-fit replacement for a worn lower control arm or ball joint. The reviewer found the assembly to be an OE replacement-style unit that matches original geometry and bolting points, making it a sensible choice for a mechanic or DIYer looking to restore front suspension alignment and handling without expensive dealer pricing.

Key Features

• Direct Fit: Installs using factory mounting points so it aligns with the vehicle without modification for a faster repair.
• OE Replacement Assembly: Includes the control arm and ball joint in one unit to remove the guesswork of matching separate parts.
• Vehicle Specific Fitment: Fitment notes cover 1999-06 Silverado and Sierra 1500, Tahoe, Suburban, Yukon and Avalanche to help ensure correct selection.
• OE Reference Numbers: Cross-referenced to common OE numbers such as 12472817 and 12475479 so buyers can confirm compatibility with factory parts.
• Aftermarket References: Multiple aftermarket cross numbers are provided, aiding identification for shops that use reference lists.

Who It's For

This control arm is best for owners of 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500 models, plus compatible Tahoe, Suburban, Yukon and Avalanche vehicles, who need a reliable direct-fit front lower control arm and ball joint assembly. It suits both independent mechanics and competent DIYers replacing a failed arm or refreshing worn suspension components to restore steering stability.

Those who should look elsewhere include owners with non-standard suspension conversions or aggressive off-road builds where upgraded heavy-duty arms are preferred; also verify vehicle-specific torsion bar or 4x4/2WD distinctions before ordering, as fitment differs on some rear wheel drive torsion bar models.

Pros & Cons

Pros

• Good fit and match to original parts, making installation straightforward for most technicians.
• Combined control arm and ball joint saves time compared with replacing separate components.

• Reported value for money compared with dealer-priced parts.

Cons

• Some customers reported isolated issues with the ball joint, so inspection on arrival and attention during installation are advised.
