Ever wonder how the front suspension on a 2004 Nissan Frontier works? The 2004 Nissan Frontier has the very popular double wishbone, independent front suspension which is braced with a stabilizer bar and uses torsion springs. The MacPherson strut, a combined coil and shock absorber arrangement, allows the suspension "package" to be more compact and more efficient than previous suspensions. It is also lighter; therefore manufacturers, including Nissan, are drawn to using this set up.
The independent suspension is configured by two wishbones, which are attached to the top and lower part of the suspension strut. These are connected to the chassis legs or rails and offer a solid base to start from.
The combined shock absorber and coiled spring offer the damping and shock absorption, which reduces the jolts from bumps being transmitted throughout the cabin. The Nissan Frontier is a fairly heavy vehicle at 4,025 pounds. Therefore, the car needs to be sufficiently suspended, especially with a heavy 3.3L V6 supercharged engine and the payload capacity of an additional 1,080 pounds.
Between the suspension struts is a stabilizer bar. This effectively connects the two suspension units together, allowing them to act as one. This gives the Nissan a greater "feel" when it comes to road holding and a comfortable ride because the suspension is working in unison.
The stabilizer bar (also known as a sway bar) helps keep the vehicle level. If one front wheel goes over a bump or a raised section of road, the sway bar helps keep the other wheel on the road surface. The sway bar transfers the energy onto the lower wheel, which in turn keeps the level of the vehicle at a more acceptable level. Sway bars also reduce the body roll felt in corners. This additional stability helps the driver have more confidence and gives greater control over the vehicle in all conditions.
