Third Generation (1996 to 2002)
The next 4Runner introduced for 1996, and offered until
2002, featured a larger body sitting on a new chassis, and the wheelbase was
stretched 2 inches. This was the first year that the 4Runner would not share
the same body panels or frame with its companion truck model. With the
introduction of the Tacoma line and the third-generation 4Runner in 1996, the
front suspension was swapped over to a coil spring independent double wish bone
setup. Front suspension travel increased 25 percent or more with this change.
Toyota has stayed with this basic style of suspension up to the current models.

Most all IFS models came with gas-charged shocks and
stabilizer bars. Beginning with the 1996 models, the steering was changed over
to power assisted rack-and-pinion.
Larger four- and six-cylinder engines were introduced in the
third-generation 4Runner. These were the 2.7L 3RZ-FE I-4 (until 2000) and the
3.4L 5VZ-FE V-6 multi-cam, multi-valve engines. Manual transmissions were last
offered in the 2000 models. Starting in 2001, all 4Runners with the 3.4L V-6
engine were equipped with a four-speed automatic transmission.

Axle gear ratios were available to handle the different
drivetrains and tire sizes, with ratios of 3.91:1, 4.10:1, 4.30:1, and 4.56:1.
Also, in 2001, the brake booster was changed to hydraulic assisted. Toyota had
been offering an electric locking differential in its FZJ- 80 Land Cruiser line
since 1993. This proven differential style was then made available as an option
on some third generation 4Runners through 2000. The locker is engaged using a
dash-mounted switch.
In 1999, Toyota introduced their multi-mode 4WD system on
the Limited models. The full-time all-wheel-drive system has 2WD capability and
was designed to tackle all driving surfaces, including dry pavement. Vehicle
Skid Control was included with traction control.

Body size and weight bloated a bit in the third generation,
but these models make greater exploring rigs and offer improved interior
comfort, along with an improved front suspension. The 3.4L V-6 is an excellent
performer, and you can have your choice of automatic or manual transmission in
the 2000 and earlier year models.
Fourth Generation (2003 to 2009)
Toyota made its most drastic body changes to date when it
introduced the fourth-generation 4Runner, which was produced from 2003 through
2009. The 4Runner grew once again to become wider and longer with a 109.8-inch
wheelbase.
Some fourth- and fifth-generation 4Runners came equipped
with the X-Relative Absorber System (X-REAS) that linked the damping of shocks diagonally
on the vehicle using hydraulic hoses). It was used to counteract vehicle sway,
but can be expensive to repair or replace with factory components.
