Greetings from San Diego. I am new here and I hope I am doing this correctly.
Last weekend I replaced the right front axle (passenger side) on my wife's 2002 v70 T 5. I took it for a test drive on a road that was curvy and it seemed fine. I drove it the next day and noticed when I accelerated on a straight road the car pulled strongly to the right. The alignment was done a bout 6 weeks before that and I didn't experience this torque steer before the axle replacement. Anybody know what I did wrong? I bought an EMPI axle from IPD they were helpful in that they verified that that was the correct axle.
Thanks

 

Axle metal softer than oem axle, allowing more twist than original would be my guess

 

Me too. That's a brilliant guess. It is also one of the reasons one NEVER replaces CV shafts one side at a time.

 

I seriously doubt the replacement axle is flexing THAT MUCH......if THAT WERE the case the replacement axle would break after a short while... IMO

 

Your car only provides output to one wheel at a time, be that the L or R, torque is the effect of that drive wheel having traction and pulling the car forward from one side of the car, not evenly, as if both wheels were doing the pulling, hence the directional pull. The drive wheel is accually trying to pull ahead of the non drive wheel because it has traction and is doing all the work, the other wheel is just along for the ride. The reverse would be true as well. If you had brakes only on one side of the car and applied them the car would pull towards the braking side. In answer to your question, your car hasn't changed it's torque steer charicteristics because of the new axle, you just took more notice of it.
