2.3 Measuring Leaf Springs

If the original equipment (OE) number is unavailable, or if vehicle application data is insufficient, accurate measurements of the relaxed spring (off the vehicle) are critical for selecting the correct replacement. Refer to the diagram below for measurement points.

3. Mazingatio ya Uendeshaji

Once installed, the Dorman 22-1487 leaf spring functions as part of your vehicle's suspension system. Proper operation involves understanding its role and limitations.

Uwezo wa Kupakia: Adhere to your vehicle's manufacturer-specified Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Rating (GAWR). Overloading can prematurely wear out or damage leaf springs and other suspension components.
Driving Conditions: While designed for durability, extreme off-road conditions or heavy impacts can stress suspension components. Drive cautiously on rough terrain.
Ride Quality: A new leaf spring may alter the vehicle's ride height and feel. Allow for a break-in period. If significant changes or discomfort are noted, consult a technician.

4. Matengenezo

Regular inspection and maintenance can extend the life of your Dorman 22-1487 leaf springs and ensure continued safe vehicle operation.

Ukaguzi wa Mara kwa Mara: Visually inspect the leaf springs during routine vehicle maintenance (e.g., oil changes, tire rotations). Look for signs of rust, cracks, bent leaves, or damaged bushings.
Usafi: Keep the leaf springs and surrounding areas free from excessive dirt, salt, and debris, which can accelerate corrosion.
Vichaka: Check the condition of the bushings at the ends of the leaf springs. Worn or cracked bushings can lead to noise and reduced suspension performance. Replace as needed.
Bol-U: Ensure U-bolts remain tight. Loose U-bolts can cause the leaf spring pack to shift, leading to damage or unsafe conditions.
