Frequently Asked Questions About Volvo VNR Air Springs & Level Valves
What are the most common signs that my Volvo VNR air springs need replacement?
Watch for these telltale signs: your truck sits lower on one side when parked, you hear air leaking sounds near the suspension, the ride becomes noticeably rougher or bouncier, or your air compressor runs more frequently than normal. Additionally, if you notice visible cracks, dry rot, or damage to the rubber bellows during pre-trip inspections, it's time to replace them. Most drivers report air springs typically last 3-5 years depending on load conditions and maintenance.
Will these air springs and level valves fit my specific Volvo VNR model year?
Air springs and level valves for Volvo VNR models are generally compatible across 2018-2024 model years, but there are important distinctions. VNR 300, 400, and 640/660 models use the same basic air spring design, though mounting brackets may vary. Always verify your truck's specific suspension configuration (standard vs. heavy-duty) and axle rating before ordering. Check your door jamb sticker for the suspension code or contact us with your VIN for exact fitment confirmation.
Can I replace air springs myself, or do I need special tools and equipment?
While air spring replacement is doable for experienced mechanics, it requires proper safety equipment and some specialized tools. You'll need heavy-duty jack stands rated for commercial vehicles, a reliable floor jack, basic hand tools, and ideally an air impact wrench. The job typically takes 2-3 hours per side. Critical safety note: always properly support the frame and relieve all air pressure before beginning. Many drivers report the hardest part is breaking loose corroded mounting bolts, so have penetrating oil ready.
What's the difference between OEM and aftermarket level valves, and which should I choose?
OEM level valves typically cost 40-60% more but offer exact factory specifications and proven reliability. Quality aftermarket options from brands like Hendrickson and Reyco provide comparable performance at lower cost, often with improved corrosion-resistant coatings. The main difference is warranty coverage - OEM parts usually carry 12-month warranties while aftermarket may vary from 6-24 months. Most fleet mechanics report no significant performance differences when using reputable aftermarket brands.
How do I properly adjust the level valve after installation to maintain correct ride height?
Proper level valve adjustment is crucial for optimal performance. Start with the truck on level ground and air system at normal operating pressure (typically 90-120 PSI). The valve arm should be parallel to the ground when the suspension is at proper ride height. Adjust the linkage rod length so there's no tension pulling the arm up or down. Small adjustments make big differences - typically 1/4 turn equals about 1/2 inch of ride height change. Always test drive and re-check after adjustment, as settling may occur.
