Torque Steer
1996 L.... Just for opinions, I have definite torque steer , my initial thought is duty solenoid C (?) I have a CEL atm, but it's for an O2 sensor.

Re: Torque Steer
In the world of 4x4, we attribute torque steer to worn out suspension bushings. I'd be curious to learn what causes this in the SVX world!

Re: Torque Steer
I don't know what it could be other than a failing/failed front differential. Does it always pull on the same side or is it random every time? Rapid back and forth? IDK if it would make a difference anyway.

Re: Torque Steer
You will feel torque steer because the car is in 90% FWD unless it detects wheel spin and then power will be transferred to the rear wheels as necessary. A duty solenoid C problem is usually felt at low speed when turning sharply, such as doing a slow figure 8. The car will shudder and hop slightly like a 4WD truck turning on dry pavement with the 4WD engaged (crow hopping).

Re: Torque Steer
My understanding of "torque steer" is that it's caused by "power" (rotational force) taking different length paths to get the wheels, the short path gets more force. The outcome is that the car tries to turn, normally away from the side getting the most power.
Front wheel drive vehicles often have this because they have a transposed engine and transmission (rotated 90 degrees), results in the transmission being on the side of engine, and closer to one wheel than the other. Subaru has a more balanced system power transmission system, with the transmission and engine centered in the car, and power travels equal distances to the wheels (left to right anyway, front to back is different but not so relevant to torque steer). So, how are you folks seeing torque steer? Or what is wrong with my model/idea of torque steer? If it was my car, would be looking for other causes, such as a stuck brake pad/caliper (I've had that before), worn out bear/stub axle (I've had that as well), worn out ball joint (I've had that as well), power steering issues, warn bushings, wheel alignment issues (is tire wear even), damaged CV joints (I've had that, but I didn't remember it effect steering on me), etc.. Cheers, Ian. |

The Subaru set-up completely eliminates the most common reason for torque steer, which therefore does not become a factor in respect of handling. Cheers, Trevor

Re: Torque Steer
Well, I noticed one day, when i took off rather suddenly, front wheel spin and it acted very much like a front wheel drive under heavy acceleration.

Re: Torque Steer
The transfer clutch is not coming on to drive the rear wheels. if you get a code 24, it is the C solenoid, if you don't get a code, it can be the transfer valve that the C solenoid works.
I would not let it spin the front wheels as the load on the front diff can break it.

Re: Torque Steer
I used to have lots of torque steer with my 1987 honda civic LX turbo - caused because of unequal length drive shafts .... running 20lb boost and water injection .... 1300cc clocked at 225km/h down the main straight of Pukekohe race track it was at times a wild ride, it was my DD and in the 12 years I had her I did 250,000km

Re: Torque Steer
It's already started a bearing whine. I'll double check to see what codes I have and put it up on stands , put it in gear to see how the wheels react. uh

Re: Torque Steer
When you run it on the stands, the rear wheels may rotate from the clutch drag, you may have to pull the handbrake on see if the rear stop.

The front wheels should be chocked or resistance applied, while the rear wheels are checked for adequate torque and the hand brake could assist in the regard. Otherwise the test as suggested, will disclose nothing more than that there is clutch drag turning the rear wheels.

However, what is the point of the test in respect of analysing a problem involving torque steer? I have never seen FWD models being criticised as having this problem. Indeed why should they?
