In response to complaints of steering wobbling in 2005 to 2010 model year Jeep Wranglers, a technical service bulletin was released by Chrysler Group for dealers and drivers. The steering system of the older Jeep Wranglers with a solid front axle may show vibrations when there’s damage and when there’s no proper maintenance.
Chrysler informed owners that if a wobble is noticed, they should bring their vehicle to a dealer. The Chrysler bulletin said that aftermarket components like lift kits, wheels or suspension components that are intended for off-road use or aren't built for the Wrangler are the most common causes of the vibration.
The National Highway Traffic Safety Administration said that the vibration, referred to as "The Jeep Death Wobble" by two Democratic members of Congress, can be felt more frequently at speeds of more than 45 mph on bumpy surfaces. So far, the NHTSA has gotten more than 400 complaints about the wobble. The agency said that these vibrations have been observed on other vehicles too.
Last April, the agency said that it isn’t planning to open a formal investigation into the issue. Chrysler was applauded by Rep. Anna Eshoo and Rep. Henry Waxman for issuing the bulletin. Earlier this year, Eshoo and Waxman had requested the agency to probe the matter. In a statement, Eshoo said that those who felt the “wobble” are rightfully worried about their safety.
Eshoo states that Chrysler's decision to officially make a disclosure on how to repair this problem is the right thing to do for its customers’ and for others’ safety on the road. Chrysler said that the bulletin was distributed to improve the ability of dealers to diagnose and fix the steering system.
With more than 70 years of 4x4 engineering experience, the Jeep Wrangler gives you unmatched off-road capability with its legendary 4-wheel drive. It continues to boast a body-on-frame design, live axles, electronic lockers, and a front/rear 5-link suspension system.
Now, Jeep Wrangler offers you a choice of 2 transmissions: a 6-speed manual and a 5e-speed automatic gearbox.
Jeep engineers have meticulously optimized the sound and ride characteristics of the Wrangler's body-on-frame design, along with its new powertrain. Also contributing to overall improvements to the Wrangler are revised suspension calibrations, as well as new motor and new transmission adaptations.
Moreover, interior sound quality has been greatly improved, thanks to the refinements in the vehicle’s powertrain mounting system and the noise damping in its firewall. Also, the first Wrangler engine cover has been included so as to effectively isolate the vehicle’s cabin from noises coming from the road surfaces and the engine. Engine noise is hardly perceptible when idle.
Additionally, with the new Wrangler’s 3.6-liter V-6 engine, all of its accessories are directly mounted to the engine without any accessory bracket. This helps make sure that all accessories, like the power steering pump, the alternator and the air conditioning compressor, are firmly anchored and are less susceptible to noise and vibration.
Shocks were also designed and retuned for optimum balance between rugged off-road capability and advanced on-road handling.
