oriented u-joints??

[Crazy4408pac]

What is meant by this? And, how do I do it? Getting ready to install my new driveshaft. What's the correct pinion angle I should set it at?
Thanks

Only orientation I ever worried about was if the U-joint had a grease zerk, I made sure it was accessible (usually facing towards the driveshaft) if it was in the U-joint at an angle. As for your pinion angle...if you are using a stock, or available to your car rear end, the pinion angle should be fine.

I have an 8 3/4 rear. I just installed new springs.

The grease zerk must be installed under "Compression". What this means it that the driving member must push towards the grease zerk, and not pull it. As long as you push into the drilled hole all is ok, but if you pull away from the drilled hole, it can rip the joint apart.

So, how do you install it... Looking into the front yoke, the shaft turns CW, so position the zerk in between the yoke ear and the shaft ear. In the rear, you would position the zerk in between the shaft ear and the axle yoke ear.

Hope this is clear enough.

The orientation of the joints is 90 degrees, it's already that way on your driveshaft.
The pinion angle depends on your suspension, stock with no traction aiding devices should be between 5 and 7 degrees down.
The idea is that under hard acceleration the pinion on the axle will move up a certain amount (axle wrap), and you want it parallel with the trans output shaft under load.

You first measure the angle on the trans output shaft or yolk, then transfer that angle to the rear end yolk so they are parallel and go down 6 degrees from there.

Did the new springs move the car up any vs stock height? If not, don't worry about pinion angle but if they did, you might need to check it.

Oriented u-joints means they are made by orientials in china and they all rook-a-rike::naka:

oriented I think that this is in reference to a drive shaft with a slip in between the ujoints so you keep them in phase so they donot vibrate also the angles have to cancel each other

You want the angle to be about 2-3 degrees but equal (and opposite) from end to end. Use a good magnetic protractor and reference the U joint cups or a machined surface on the yoke.
