SAFE Drive shaft angle

Postby Collers9640 » Sun Sep 27, 2015 5:24 pm

Does anyone know what the proper drive shaft angle/slope in degrees is for the W250 and what's the max angle/slope.

In terms of proper driveshaft angle, there relative to one another, in relation to output/input ends of the shaft.
For single carden ujoint setups, like our rear driveshafts, the rear axle pinion end should be equal or 1* less than the tcase output angle.
For double carden, or CV ujoint setups, the rear axle pinion angle should be zero, as in points right at the CV setup, the pinion yoke having the same angle as the driveshaft.

If you Google ujoint angles, there's aton of links and articles about angles, setups, and pictures.

For maximum angles, all depends on your size of joint, but usually they last longer if the angles aren't as severe. Wish I could remember where I saw it, but Spicer had a chart that listed different ujoints and there life expectancy at different angles

It's a little bit of a complicated thing to read about without some sort of visual reference. You will want at least 1* angle on everything for proper lubrication of u-joints, and no more than 3* at intersections. This video will explain a lot, it's a pretty old and dull video but does a great job breaking it down.

Buy an angle finder from any hardware store ($10-$20) to measure your angles. Just make sure when you're taking angles that the truck is on a level surface. Make sure to keep track if the angle is UP or DOWN. Most of the angles should be down if it's correct. The tool looks like this:
