I centered the trans tail shaft in the frame and bolted the cross member to the trans mount. I found the the cross member to be off center by almost a half inch. I then measured the pinion center line on the rear axle and discovered the pinion is also offset a half inch between the brake back plates.
What's going on here? Do I offset the tail shaft of the trans to match the rear end?
???

(till you calculate total universal joint operating angle) The most important part is having the centerline of both the transmission and the pinion be parallel. Basically you put the engine wherever you want, but be sure the trans output shaft and the pinion are parallel This tech tip has links to manuals that will explain it all in detail. http://www.stovebolt.com/techtips/driveline/setup/index.htmlGrigg | | | | | Joined: Feb 2000 Posts: 5,228 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,228 | Follow Grigg's advice, it will work just fine. U-joints need some angle to work right, ever look at a long straight truck or box truck? The driveline goes up and down at each joint.
If the transmission tail shaft is pointed down 3 degrees, the pinion should be pointing up 3 degrees, or close to it. Side to side as you have isn't much of a problem, its most likely only a degree or so off. Joe | | |
