Parts Diagram of Front Suspension for 2010 Nissan Altima 2.5S

Understanding the front suspension of your 2010 Nissan Altima 2.5S is essential for proper maintenance and repairs. This article provides a detailed parts diagram and explains each component's function, common failure points, and replacement tips. Whether you're a DIY mechanic or just trying to understand a diagnosis, this guide will help you identify the parts and their roles.

Front Suspension Overview

The 2010 Nissan Altima 2.5S uses a MacPherson strut front suspension with a stabilizer bar. This design combines a strut (shock absorber and coil spring assembly) with a lower control arm and other linkage components. The system provides a balance of ride comfort and handling.

Key Components in the Diagram

• Strut Assembly: Includes the shock absorber, coil spring, and upper mount. The strut connects the wheel hub to the vehicle body and absorbs road impacts.
• Lower Control Arm (LCA): Connects the wheel hub to the subframe. It has two bushings (front and rear) and a ball joint at the outer end.
• Stabilizer Bar (Sway Bar): Reduces body roll during turns. Connected to the lower control arm via end links.
• Stabilizer Bar Link (End Link): Links the sway bar to the control arm. Commonly fails, causing clunking noises.
• Steering Knuckle: Holds the wheel hub and attaches to the strut, control arm, and tie rod.
• Tie Rod End: Connects the steering rack to the steering knuckle.
• Ball Joint: Part of the lower control arm (integral on many models). Allows steering and suspension movement.
• Strut Mount (Upper Mount): Attaches the top of the strut to the vehicle body and includes a bearing for steering.
• Dust Boot and Bump Stop: Protects the strut rod and limits compression.

Detailed Parts Diagram Explanation

Below is a visual description of the front suspension layout (imagine a diagram from the front view).

Upper Section

• The top of the strut assembly bolts to the strut tower in the engine bay. The strut mount has three bolts and a central nut.
• The coil spring sits between the lower spring seat (on the strut) and the upper spring seat (part of the mount).

Middle Section

• The strut body extends downward, with the shock absorber rod inside a dust boot.
• The steering knuckle is attached to the strut via two bolts at the lower end of the strut.
• The tie rod end connects to the rear side of the knuckle.
• The stabilizer bar link connects from the sway bar (mounted to the subframe) to a bracket on the strut or lower control arm (on Altima, it attaches to the strut).

Lower Section

• The lower control arm (LCA) attaches to the subframe at two points: front and rear bushings. The outer end of the LCA has a ball joint that presses into the steering knuckle.
• The wheel hub and bearing assembly are pressed into the knuckle.
• The drive axle (CV axle) passes through the hub and attaches to the wheel.

Common Issues and Replacement Tips

Strut Assembly

• Symptoms: Noise over bumps, excessive bounce, fluid leakage. Recommend replacing in pairs. Use OEM or high-quality aftermarket (KYB, Monroe).
• Tip: When replacing, consider a quick-strut (pre-assembled) to save time on spring compression.

Lower Control Arm

• Symptoms: Clunking, wandering steering, uneven tire wear. The rear bushing often wears first. The ball joint may develop play.
• Tip: Replace the entire arm (bushings and ball joint) rather than pressing in new bushings—cost-effective and easier.

Stabilizer Bar Links

• Symptoms: Clunking or rattling over bumps, especially when turning. Very common failure.
• Tip: Check for loose or broken ends. Replace both sides at once. Aftermarket links are affordable and effective.

Tie Rod Ends

• Symptoms: Loose steering, steering wheel vibration, uneven tire wear. Check by rocking wheel side-to-side.
• Tip: Always get an alignment after replacement. Use OEM or Moog problem solver for durability.

Ball Joints

• Symptoms: Clunking when turning or braking. Can separate if severely worn—dangerous.
• Tip: If the lower control arm is replaced, the ball joint is included. For separate replacement, ensure proper torquing.

How to Read the Diagram for Repair

When using a parts diagram for ordering or repair:

• Identify the component by shape and location. The steering knuckle is the large metal piece behind the wheel.
• Note bolt sizes: common bolts are 14mm, 17mm, 19mm. Sway bar link nuts are 14mm or 12mm.
• Check the diagram for part numbers. Many aftermarket brands list cross-references.
• Use the diagram to plan disassembly order: usually, you start with the strut top nut, then wheel, then brake caliper, then lower components.

Recommended Replacement Parts for 2010 Altima 2.5S

• Struts: KYB Excel-G or Monroe OESpectrum (both gas-charged, match OEM).
• Lower Control Arms: Moog RK621206 (driver side) and RK621207 (passenger side) – includes ball joint and bushings.
• Stabilizer Bar Links: Moog K750299 or Duralast 521-149.
• Tie Rod Ends: Moog ES3484 (inner and outer set).
• Strut Mount: Moog K960102 (includes bearing).

Practical Recommendation

If you're tackling a front suspension repair on your 2010 Nissan Altima 2.5S, start by identifying the source of the problem using the symptoms above. For a complete refresh, consider replacing struts, lower control arms, and stabilizer bar links simultaneously—many components are interconnected, and you'll save labor. Always use a quality aftermarket brand like Moog or KYB; they offer reliable performance at reasonable cost. And don't forget a professional alignment after any suspension work. Use the parts diagram as a roadmap—it will help you order the right parts and avoid surprises during the job.
