At certain speeds you'll feel or hear a vibration, without even having to put your hand on the shifter.Mike In the past 30 days, my drive shaft has been shortened (don't know if a balance was done) due to a 4 - 5 speed conversion and I've switched differentials.The 5speed conversion was professionally done and my neighbor and I did the diff swap.

Island arcs. An island arc is a curving series of volcanic islands that are created through the collision of tectonic plates in an ocean setting. The particular type plate boundary that yields island arcs is called a subduction zone . In a subduction zone, one lithospheric (crustal) plate is forced downward under an upper plate.
The Hawaiian Islands were formed by volcanic activity. The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. Each island or submerged seamount in the chain is successively older toward the northwest.o, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed. The Hawaiian Islands form an archipelago that extends over a vast area of the North Pacific Ocean.
