Ron Gaul, Longmont, CO, 1971 Dodge Challenger 340
I was told when replacing the driveshaft in a 1971Challenger, that I would have to reset the pinon preload. Is this true, andif so, why? Thank you, Ron
Ron, this is NOT true. That caveat only applies if you swap the pinion yoke(flange) on crush-sleeve type axles. Even then, you just measure the turningtorque and make sure it remains unchanged when you swap on the new yoke (orpinion seal, etc).
