cv boots torn
Posted to Technical Theory Forum on 8/28/2012 8 Replies

I've been in a bit of a discussion about the cause of frequent torn outer cv joint boots on a customers car. A new axle assembly was installed and a few weeks later the customer comes back for routine maintence and notice the new axle boot torn. A new axle is installed under warranty. Now a few months later the car comes back for another repair and again notice the same axle has torn the outer boot again. A coworker states that the number one cause of torn boots is from faulty motor mounts. That rear drive vehicles with cv axles dont tear because of no movement. I say its because front axles not only have suspension movement but also constanlty are extending from turning of the steering direction also where as the rear just move independantly with the suspension. Any feed back on this subject is greatly appreciated.
