What Is Suspension Line Part Number 58978?

Common Applications of Part Number 58978
This part number is most frequently used on:
- Chevrolet Silverado 1500 (1999–2006)
- GMC Sierra 1500 (1999–2006)
- Chevrolet Suburban (2000–2006)
- GMC Yukon (2000–2006)
- Cadillac Escalade (2002–2006)
It may also fit other GM trucks and SUVs with similar rear suspension designs. Always verify fitment using your vehicle’s VIN or by consulting a parts specialist.
How to Identify the Correct Part
Before you purchase part number 58978, confirm it matches your vehicle’s requirements. Here’s how:
Check the Original Part
If you still have the old component, look for a stamped part number. The number 58978 should be visible on the metal or plastic body. Clean off any grease or dirt to read it clearly.
Measure Dimensions
Suspension line parts vary in length, diameter, and bushing size. For this part, typical specs include:
- Center-to-center length: approximately 160 mm
- Thread diameter: 10 mm
- Bushing inner diameter: 14 mm
Use a caliper or ruler to measure your old part. Compare to OEM specifications to ensure a match.
Verify Vehicle Compatibility
Use online lookup tools from major auto parts retailers or the manufacturer’s website. Enter your vehicle’s year, make, model, and engine size to see if part number 58978 is listed as a replacement.
Where to Find the Nearest Suspension Line Part 58978
Locating a genuine OEM or high-quality aftermarket part near you involves several reliable channels.
Authorized GM Dealerships
The most straightforward source is a local Chevrolet, GMC, or Cadillac dealership. They stock genuine GM parts and can verify fitment with your VIN. Call ahead to check availability. Many dealerships offer competitive pricing and can order the part if not in stock. Use the dealer locator on the GM website to find the nearest location.
Well-Known Auto Parts Stores
National chains like AutoZone, O'Reilly Auto Parts, Advanced Auto Parts, and NAPA Auto Parts carry part number 58978 or its equivalents. Their inventory often includes both OEM and aftermarket options. Visiting their websites or calling the store you plan to visit can confirm stock. Many offer same-day in-store pickup or free next-day delivery to the store.
Independent Auto Parts Shops
Local independent parts suppliers sometimes have access to OEM parts or high-quality aftermarket alternatives. They can often source the part faster than big retailers. Build a relationship with a trusted local shop—they can help with future suspension needs as well.
Should You Buy OEM or Aftermarket?
For a component like a stabilizer link, both OEM and aftermarket parts can work well. Here are considerations:
OEM (Part Number 58978)
- Exact fit, same material and design as original
- Usually comes with a warranty
- Slightly higher cost
Aftermarket Equivalents
- Often lower price
- May use improved materials (e.g., greasable bushings)
- Quality varies by brand (prefer established brands like MOOG, Mevotech, or AC Delco)
If you prioritize longevity and exact specifications, OEM is a safe choice. For budget-conscious replacements, a reputable aftermarket brand often performs just as well.
Installation Tips for Part Number 58978
Replacing a stabilizer bar end link is a moderate DIY job. But if you’re not comfortable working on suspension, hire a professional mechanic.
Tools Needed
- Socket set (metric)
- Torque wrench
- Jack and jack stands
- Penetrating oil (for rusty bolts)
- Anti-seize compound
Steps
- Raise the vehicle and support it securely on jack stands.
- Remove the wheel on the side you’re working on.
- Spray penetrating oil on the link bolts and let it soak.
- Remove the old link nuts and bolts. You may need to hold the link with a wrench while turning the nut.
- Install the new link. Tighten the nuts to the manufacturer’s torque specification (typically 30–40 ft-lbs).
- Repeat for the other side—always replace links in pairs.
- Reinstall the wheel, lower the vehicle, and test drive.
Safety Precautions
- Always use jack stands; never work under a vehicle supported only by a jack.
- Torque all fasteners to spec.
- After installation, check for any looseness or rattles.
How to Ensure You’re Getting the Right Part
Mistakes in parts ordering can delay repairs. Follow these tips:
- Use your VIN when checking compatibility.
- Take a photo of the old part and its location.
- Compare bushings: The new part should have the same bushing style (e.g., rubber vs. polyurethane).
- Check thread pitch: Some aftermarket links use different thread sizes; confirm yours matches.
Practical Final Recommendation
When you need the nearest suspension line part number 58978, start by contacting your closest GM dealership or a major auto parts retailer like NAPA or AutoZone. Call ahead to confirm stock and ask about warranty. If you are replacing a rear stabilizer link on a 1999–2006 Silverado or Sierra, this part is likely the correct one. For a straightforward repair, buy an OEM part from a dealer or a high-quality aftermarket replacement from brands like MOOG. Always replace both sides (left and right) to ensure balanced handling. If you’re not confident in DIY installation, take the part to a trusted mechanic—labor costs are relatively low for this job. Getting the exact part and installing it correctly will restore your vehicle’s stability and ride quality.
