Thought you guys might find this interesting. Swamping a drivetrain component is a surefire way to lighten your wallet...hard to beat the insurance installing an extension can give you!!
O my trucks axles I ran enough 1/4" fuel hose to allow for travel and in the end I use a piece of 1/4" copper tubing formed into a spiral that makes 3 revolutions
ending with the open end of tubing pointing down and secure it to the frame.So far so good.
