Explaining driveshaft angles

[Limey57]

The video is only just over 2 1/2 minutes long but manages to explain things better than endless conversations or paragraphs in a book could ever do!  I knew the basics but after watching that it really brings home the importance of phasing driveshafts.  I guess a lot of folks on here know this, but for those that don't:

Gary, thanks for that link. It is extremely informative in a very simple demonstration! My first exposure to the concept.

For years I've been listening to people banging on about driveshaft angles and while I thought I understood it actualy seeing it demonstrated makes me realise I didn't fully understand it before.  I love videos like that.

Nice video.

Read alot (emphasize on ALOT)of stuff on driveshaft/pinion angles...learned more in that 2 1/2 minute video...thanks for posting.

   Thanks for that information.   There are lots of people that will benefit from it.  Jay

Thanks,
This is great reference info.

Thanks for that!!!!!  I thought I understood it as well, but that really makes a lot of sense, and will definitely make me pay more attention next time I mount up an engine and trans. combination.  I had no idea that the driveline sped up and slowed down.  Makes sense on why we sometimes have some bad stuff happening and don't know why. Thanks again.

Gary...I reposted your link to the video in the "Tech Link" area so we could find it easier later on. Thanks again.

I've always wondered what the effect would be. All you ever heard was don't make drastic changes. This shows you why. When I installed my Tremec I noticed the back of the engine was down a bit (possibly 1-2") but I never gave it much thought as that would be too much. I did see where a lot of guys were raising the hump of their cars but thought that was just over compensating.
I've never had a vibration that I could feel and my U-joints have always been good. This week when I took my driveshaft out to have the 1350 ends put on it the u-joints were good and they've had at least 30K miles put on them. There must be some degree of change that is unnoticeable. Wish I knew what that was. Jim

Normally about 2 degrees difference won't hurt anything, more then that starts causing problems. Ideally the pinion angle and the trans angle should be exactly parallel.
EXAMPLE:  If the trans is down -2 degrees the pinion should be up + 2 degrees..

   That's the way I have been doing it for years and it works with no problems.

I love demonstrations like this that teach without making anyone feel stupid. Straight and to the point.
