Energy Suspension 4.7126G Front Track Bar Bushing Set
What is Energy Suspension Part 4.7126g?
Energy Suspension part 4.7126g is a polyurethane bushing typically used in suspension systems. Unlike rubber, polyurethane resists compression set and deformation, providing consistent performance over time. This specific part number corresponds to a bushing that fits certain vehicles—check your application before purchase. The "4.7126g" designation usually indicates a package that includes the bushing, sleeve, and necessary hardware. It's designed to be a direct replacement for the factory rubber bushing, but it requires proper installation to avoid premature wear or noise.
Tools and Materials Needed
Before starting, gather the following:
- Jack and jack stands (or lift)
- Lug wrench
- Socket and wrench set (metric and standard)
- Torque wrench
- Pry bar or bushing removal tool
- Wire brush or sandpaper
- Energy Suspension Super Grease (included with many kits)
- Clean rags
- Safety glasses and gloves
Having the right tools prevents frustration and ensures a safe installation.
Step-by-Step Installation Guide
1. Prepare the Vehicle
Park on a level surface and engage the parking brake. Loosen the lug nuts on the wheels you'll be working on, then jack up the vehicle and secure it on jack stands. Never rely on the jack alone. Remove the wheel to access the suspension component.
2. Remove the Old Bushing
Locate the bushing (e.g., control arm bushing or sway bar bushing). Depending on the design, you may need to unbolt the component from the frame. Common methods to remove the old rubber bushing:
- Use a bushing removal tool or press.
- Drill several holes in the rubber, then chisel it out.
- Burn or cut the rubber (if metal shell remains, remove with a saw or grinder).
Be careful not to damage the mounting bracket or control arm. If the bushing is pressed in, a hydraulic press or C-clamp with appropriate cups works best.
3. Clean the Mounting Area
Remove all rust, debris, and old rubber residue from the mounting surfaces. Use a wire brush or sandpaper to smooth the inside of the bracket or control arm bore. Wipe clean with a rag to ensure the new bushing seats properly.
4. Lubricate the New Bushing
Energy Suspension polyurethane bushings require grease to prevent squeaking. Apply a thin coat of the supplied Super Grease to the outer surface of the bushing and the inner sleeve. Also grease the contact points in the mounting bracket. Do not skip this step—dry polyurethane will squeak immediately.
5. Install the New Bushing
Align the bushing and sleeve with the mounting holes. Press or tap it into place using a hammer and a block of wood, or use a bushing installation tool. Ensure the bushing is centered and the sleeve protrudes evenly on both sides. If the part includes washers or spacers, install them as shown in the included diagram (often found in the package).
6. Reassemble and Torque
Reattach the suspension component to the vehicle. Install bolts loosely first, then tighten to manufacturer specifications using a torque wrench. For polyurethane bushings, torque values are usually the same as OEM. However, note that some bushings should be tightened only after the vehicle is on the ground (with weight on suspension) to avoid preload. Check the instructions for part 4.7126g: if it's a control arm bushing, tighten with the vehicle's weight on the wheels; for a sway bar bushing, tighten fully in the air.
Common Mistakes to Avoid
- Incorrect grease: Use only Energy Suspension Super Grease or another compatible polyurethane grease. Petroleum-based greases can damage the bushing.
- Over-tightening: Polyurethane is stiffer than rubber; over-tightening can cause binding or damage.
- Skipping cleaning: Dirt or rust prevents proper seating and leads to premature wear.
- Forgetting alignment: After replacing suspension bushings, a wheel alignment is often necessary to ensure proper handling and tire wear.
- Not checking bolt torque: Loose bolts can cause noise and reduce performance.
Benefits of Proper Installation
When installed correctly, Energy Suspension part 4.7126g reduces suspension slop, improves steering accuracy, and enhances overall ride stability. Polyurethane bushings last longer than rubber, especially in harsh conditions. Proper lubrication ensures quiet operation, and correct torque maintains the structural integrity of the suspension.
Final Recommendation
Installing Energy Suspension part 4.7126g is a straightforward upgrade that can yield noticeable handling improvements. If you have basic mechanical skills and the right tools, it's a weekend project. However, if you're unsure about removing stubborn old bushings or don't have a press, consider having a professional installation done. Always follow the manufacturer’s instructions included with the part. After installation, test drive gently and re-check torque after a few hundred miles. This bushing is an excellent choice for restoring factory handling or upgrading for performance.
