Cosmic point Mr. Pope and right on the money....

Might as well throw in another bit of u-joint trivia. The front driveshaft on a 4X4 that never gets put in 4wd will vibrate the u-joints out much quicker than one that gets used a lot." If ya don't use it, ya lose it!"

Working in maintainence for a large company for over 20 years with many driveshafts we always set them a various angles non were streight ever . Some section of a machine may have 20 or 30 shafts that move up & down all the time. Same rule applies.
