704 Suspension Part Number: Complete Guide to Identification and Use

The 704 suspension part number appears in many OEM and aftermarket parts catalogs, often associated with control arms, bushings, or struts. This guide explains what this number typically refers to, how to confirm it fits your vehicle, and where to source the correct part. Whether you’re a DIY mechanic or a shop owner, understanding part numbers helps avoid costly returns and installation headaches.

What Does the "704" Suspension Part Number Refer To?

In the world of suspension components, the number 704 is not a universal standard. It often corresponds to a specific manufacturer’s internal code for a particular design, material, or vehicle application. For example, many aftermarket brands use three‑digit suffixes to denote bushing durometer, arm length, or mounting style. In some cases, 704 appears on lower control arms for compact sedans or on stabilizer bar links for mid‑size SUVs.

Because part numbers vary by brand, the 704 designation may be part of a longer string. A complete number like “K704” or “704‑1010” provides more context. Always look at the full number, not just the three digits, to avoid ordering the wrong part.

How to Identify the Correct 704 Suspension Part Number

Finding the exact suspension component requires more than reading a number from an old part. Follow these steps to ensure accuracy.

Using Your Vehicle’s VIN

Your Vehicle Identification Number (VIN) is the most reliable way to match parts. Enter the VIN into an OEM parts website or ask your dealer for the original part number. This method accounts for production changes, optional packages, and regional variations. Once you have the OEM number, you can cross‑reference it with aftermarket 704 parts that list compatibility.

Consulting Manufacturer Parts Diagrams

Online parts catalogs from brands like Moog, AC Delco, or Duralast include exploded views of suspension assemblies. Search by vehicle year, make, and model, then locate the component you need (e.g., front lower control arm). Look for the part number listed alongside the diagram. If a 704 suffix appears, note the full number and compare with your old part.

Measuring and Visual Inspection

If the part number is worn off, measure the length, bushing diameter, and mounting hole spacing. Compare these dimensions with specifications on the manufacturer’s site. Many 704 components are designed for a specific bolt pattern or ride height, so physical matching is a good backup.

Common Vehicles Using the 704 Suspension Part Number

While not exhaustive, the 704 code frequently appears on certain platforms:

• Compact cars (2000‑2010 Honda Civic, Toyota Corolla) – often used for rear trailing arm bushings or front lower control arms.
• Mid‑size trucks (1995‑2005 Ford Ranger, Chevy S‑10) – can refer to radius arm bushings or stabilizer bar links.
• SUV models (2000‑2010 Jeep Cherokee XJ) – may indicate a front sway bar link or control arm bushing.

The best practice is to search your vehicle’s specific forum or contact a specialist before ordering.

Sourcing the 704 Suspension Part from Dealers or Specialty Shops

To get the right part, choose a supplier that offers fitment guarantees.

• OEM dealership parts departments – give you the exact factory component, but at a premium price. Ask for the part number and verify it ends in 704.
• Specialty suspension suppliers – companies like Energy Suspension or Prothane list 704 as a product code for polyurethane bushings. Their websites allow you to filter by vehicle model.
• Local auto parts stores – counter staff can look up the 704 part in their system if you provide the full number or vehicle details.

Avoid buying used or unknown‑source parts when the 704 designation is unclear. A mismatched component can cause clunking noises, uneven tire wear, or alignment issues.

Installation Tips for the 704 Suspension Component

Once you have the correct part, proper installation extends its life and keeps the suspension geometry correct.

• Safety first – secure the vehicle on jack stands, never rely solely on a jack.
• Use the right tools – many 704 bushings require a press or socket set for removal and installation. Do not hammer directly on the bushing shell.
• Torque to specification – tighten bolts only after the vehicle is on the ground under its own weight. This prevents bushing preload and premature failure.
• Alignment required – replacing control arms or struts changes camber and toe. Schedule a professional alignment after installation.

If you are not comfortable with suspension work, have a certified technician perform the job. Safety and ride quality depend on proper assembly.

Final Recommendation

When you need a 704 suspension part number, start by confirming the full number using your VIN or an OEM parts diagram. Verify compatibility with multiple sources, and prefer new components from reputable brands. For a hassle‑free experience, purchase from a dealer or a specialty shop that offers fitment support. Taking these steps ensures you get the correct part the first time, saving you time and avoiding unnecessary repairs.
