Cant find info on this 4WD system. Wondered if mechanics can cause one front drive wheel to turn stronger than other. Seem to have problem aligning steering. Does front drive do primary load? Would like some info on how this system works.??
Take it to a Lexus dealer
From a Lexus Press Release found on google
Full 4-Wheel Drive Capability
The Lexus GX 460’s on-road smoothness and quiet ride belie its considerable trail-driving capability. It starts with true, full-time 4-wheel drive, which uses an electronically controlled transfer case and a TORSEN® torque-sensing limited slip center differential. The TORSEN differential distributes power 40:60 under most driving conditions and changes the ratio as needed based on wheel slip. The system offers a low range for off-road driving, and the center differential can be electronically locked.
The GX 460 brings its considerable 4WD capability to on-road driving, as well. As you drive through a curve, for example, the system can change the torque split to 30:70 to enhance vehicle tracking. If wheels spin, the center differential can change the ratio to 50:50 to help control the slippage. The system can respond to sudden changes in road-surface conditions, such as driving through a puddle or over an ice patch.
The off-road capability starts with a low range, and it is supported by a wide array of chassis control technology. With Downhill Assist Control (DAC), Hill-start Assist Control (HAC), Active Traction Control (A-TRAC), Vehicle Stability Control (VSC) and available Crawl Control, the GX 460 shrugs off unpaved, uneven trails and steep inclines. In some off-road conditions, the driver might have a hard time knowing which direction the front wheels are pointing, so the GX 460 comes with a standard steering angle indicator in the gauge panel.
Active Traction Control (A-TRAC) provides the traction benefits of having locking front and rear differentials, but with lower weight. The system can apply the brake to a slipping wheel, while transferring torque to the wheels with better traction.
Good info @wolyrobb … that Lexus seems to have some sophisticated 4WD and traction improvement technology for a passenger vehicle.
Can you clarify the problems you’re experiencing?
How many miles are on the vehicle?
Are you the original owner? If not, do you know anything about the vehicle’s history?
Exactly what do you mean by “seem to have problem aligning steering”?
And, with a tip of the hat to cavelle, have you taken it to a shop? What did they check/do? What did they say?
@George_San_Jose it’s also known in other markets as the Land Cruiser Prado so without the Lexus trim you might see them in pretty much every market Toyota sells cars in instead of the 4runner which shares a platform with the Lexus.
Wow! I thought my 1991 Jeep Cherokee with Select Trac had the on road/off road bases covered. Of course I’m sure a new Lexus GX 460 costs a bit more than $18,000. Sigh…
The first thing I’d check is that the tires are all the same and that they are at the same and proper pressure. On a 2013 they should be the original equipment, but we don’t know ham many miles you have on it.
