The Jeep Liberty - Diesel and Gas - Buyers Guide

2008 models

See the 2008 Jeep Liberty page. The Dodge Nitro was built starting August 2006; the redesigned Jeep Liberty, on August 2007. Toledo North, a four year old plant, was expected to produce 300,000 vehicles per year (225,250 Libertys were sold in 2006). Diesel Libertys ended at the end of 2006. See the Jeep Liberty being built (2011 factory tour)

Liberty sales were surprisingly high, with the Liberty beating the Ford Escape to be the best-selling compact SUV in America for 2005.

Drivetrain

Jeep Liberty was the first diesel-powered mid-size sport-utility in the US. The 2.8 liter common-rail turbodiesel engine was rated at an estimated 160 horsepower (120 kW) at 3800 rpm with an enormous 295 lb.-ft. (400 N.m) at 1800 rpm, providing class-leading torque and towing capability.  Diesel engines offered increased torque, towing, and range, while improving fuel economy an average of 25 percent and reducing CO2 emissions by an average of 20 percent. 

The diesel engine was available on both Sport and Limited models with a Chrysler 545RFE five-speed automatic only. This engine, a Detroit Diesel VM model, was well received in Jeeps sold in Europe for some time.

The current 2.4 and 3.7 liter engines continued, but gained a new NSG 370 six-speed manual transmission, which replaced the previous five-speed manual transmission. It was available on 4 x 2 models and 4 x 4 Sport and Renegade models. Jeep claimed it had a better feel and higher quality.

We had a detailed review of the 2005 Jeep Liberty Limited with the diesel engine option - click here to read it.

Styling

2005 Jeep Liberty

The 2005 Jeep Liberty had a freshened exterior and interior, with new front fascia, grille, foglamps, fender flares and body side-moldings.  Interior refinements included relocated power window switches, new instrument panel cluster graphics and trim bezels, and improved seat comfort. The 2005 Jeep Liberty was available (as predicted) with a diesel engine and a Renegade model.

Jeep Liberty 2005 gauges - car review

All Jeep Liberty four-wheel-drive models wore the Jeep Trail Rated badge.  The Jeep Trail Rated badge showed that the vehicle had been designed to perform in a variety of challenging off-road conditions identified by five key performance categories:  Traction, Ground Clearance, Maneuverability, Articulation and Water Fording (that was, moving through water, not blowing it up).

Suspension

Jeep Liberty clearly stood apart from car-based sport-utility vehicles in terms of capability, as well as truck-based offerings in terms of on-road refinement.  A coil spring independent front suspension and link-coil rear suspension provided an exceptional on-road ride and legendary off-road capability.  Sturdiness and four-wheel drive gave Jeep Liberty 5000 lbs. of trailer-towing capability (with V6 or diesel).

The 2005 Jeep Liberty 4 x 4 models met or exceeded the minimum requirements established by the Nevada Automotive Test Center (NATC) and Jeep Engineering. 

Marketing statements and the Jeep Liberty Renegade

Jeep Liberty had 4 x 4 capability to set it apart among a new generation of less capable mid-size sport-utility vehicles.  Since its introduction, 75% of Jeep Liberty buyers have been new to the Jeep brand. 

Starting in 2005, the new Jeep Liberty Renegade had a distinct exterior when compared to the Sport and Limited models, with a new flatter hood and taller grille, plus off-road foglamps, taillamp guards, fender flares, available all-terrain tires and higher ground clearance.  This model featured functional rock rails, four skid plates, and available P235/70R16 all-terrain tires with wider, more aggressive treads, available GPS DVD-based navigation radio and “diamond plate-inspired” seat fabric.

Jeep Trail Rated was an industry-leading methodology established by the Nevada Automotive Test Center (NATC) and Jeep Engineering to objectively measure and consistently predict off-road performance for all Jeep vehicles today and into the future.  Through a combination of natural and controlled field tests, as well as computer simulated environments, Jeep Trail Rated provided a repeatable and consistent measurement of off-road performance for all Jeep vehicles.  Only Jeep vehicles were Trail Rated.

Jeep Liberty ball joint problems and repairs

An engineer wrote, “The [ball joint] specifications were changed, the durability cycles were changed, as well as the loading factors, all downwards from standard JTE specs. This was to follow a directive to reduce cost of SUV parts, because, as so many people have noted here, SUV's aren't used offroad generally. The point is, the joints have a full lifetime as designed and predicted. The issue is not with the parts being poorly made, the issue is the wrong spec was used.”

This seemed to have originated by an argument between the Executive Engineer (just below VP of Engineering) of Vehicle Development (who was an old Jeep guy) and Financial (which had the backing of Bob Eaton). The parts met the specification, but the specification was changed to save money - as with Neon head gaskets, AC, and exhaust donuts.

All dimensions are in inches (millimeters) unless otherwise noted.

The information shown was preliminary and based on data available at the time of publication.

Allpar does not trust the weight figures since they are exactly the same as in 2004! The same may be true of gas mileage. We'd hope they'd trim some weight.
