shortening driveshaft

Post by greasemonkey060 »

has anyone had any experience in doing so???

i lowered it so much, im adding 4 degree shims to change the pinion angle so its not so drastic, and so i wont blow any u-joints.

This is one of those "shop jobs" where the best thing to do is take it to a shop and let the pros do it. The shaft needs to be cut at exactly a 90 deg angle, the yoke has to properly aligned, the welds needs to be right so the shaft doesn't fly apart. and it needs to be balanced.
Take it to a shop. :wink:

HEY no one ever answered the question about a one peice drive shaft being benificial, because I worry about two peices moving me. I'm making my rear limited slip next week and just wondered if the is any advantages.

Keep the two-piece shaft. It'll more than handle whatever you throw at it. However, converting it to a one-piece shaft will not only require a new transmission (since the one piece shaft uses a slip yoke instead of a bolt-on yoke), but the new driveshaft would end up being pretty long, and thus harder to balance and keep balanced. SWB trucks use a one-piece shaft, but there's an 18-inch difference between them and the LWB versions, so they can get away with the one-piece.
