Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What are the compatibility specifications for the 2003-2009 Dodge RAM 3500 suspension?

The suspension system for the 2003-2009 Dodge RAM 3500 is designed to fit all models within this range, including 4x2 and 4x4 configurations. It is compatible with both single and dual rear wheel setups. The front suspension uses independent coil springs, while the rear employs leaf springs. Ensure the suspension kit matches your truck's weight rating, as the RAM 3500 has varying payload capacities.

Q2

What maintenance is required for the Dodge RAM 3500 suspension?

Regular maintenance for the Dodge RAM 3500 suspension includes inspecting shocks, struts, and bushings every 15,000 miles. Lubricate suspension components every 10,000 miles to prevent wear. Check for loose bolts, worn-out leaf springs, and alignment issues. Replace shocks and struts every 50,000 miles or if you notice excessive bouncing, uneven tire wear, or poor handling.

Q3

How do I replace the suspension on a 2003-2009 Dodge RAM 3500?

To replace the suspension, lift the truck and secure it on jack stands. Remove the wheels and disconnect the shocks and stabilizer bar links. For the front suspension, unbolt the coil springs and control arms. For the rear, remove the leaf spring U-bolts. Install the new components in reverse order, ensuring proper torque specifications. Align the wheels after installation.

Q4

What are common suspension issues and how can I troubleshoot them?

Common issues include sagging rear suspension, uneven tire wear, and excessive bouncing. Sagging may indicate worn-out leaf springs or shocks. Uneven tire wear often points to alignment problems or damaged control arms. Excessive bouncing suggests worn shocks. Inspect components for damage, replace as needed, and ensure proper alignment and torque on all bolts.

Q5

How can I optimize the performance of my Dodge RAM 3500 suspension?

To optimize performance, upgrade to heavy-duty shocks and leaf springs if you frequently carry heavy loads. Ensure proper tire inflation and alignment. Consider adding a sway bar for improved stability. Regularly inspect and lubricate suspension components to reduce wear. Avoid overloading the truck beyond its rated capacity to maintain suspension integrity.
