Constant Velocity Joint ball hub & outer ring orientation - argh.
Reassembling my constant velocity joints, SC, circa 1978.
At CV joint disassembly, Warren's posted instructions state: "Please be sure that the chamfer on the inner splines of the ball hub and the larger diameter portion of the outer ring both face the driveshaft." (Page 13; Step 4 under "To assemble joint"). Questions about orientation of ball hub and outer ring: 1) On my car, ball hub sides are both chamfered - but obvious round score from concave washer edge, so driveshaft side is easy to figure out 2) "..larger diameter portion of the outer ring..." Huh? The chamfered side of the outer ring, or the flush (flat appearing) side, without chamfer? Note pics below:   These pics seems to show hub-chamfer/ring-flat combination towards driveshaft - is this correct? Many thanks for clearing this up for me. I am JUST at the point where I may be about to make a BIG mistake!

This looks correct
The first picture is the face that the cir clip rests on. (Front) 2nd picture is the shaft side (Back Side) If they are both chamfered either face would work ,I would imagine. I'm Not up on 78 Pcars

A thought - is the small green dot put on at the factory to indicate the side to face the driveshaft?
I will say it is not an either side thing - you have to be careful to install only the one side (larger diameter outer ball ring) towards the driveshaft.

oh my gosh!
What a coincidence, I just re-posted those pics on Rennlist. I originally took those top two pics for Pelican Parts. They are indeed pristine, seconds out of the box CV joints. I took those pics to show how to put them back together. Note: I've flipped them around and faced no dire consequences from doing so. Last edited by rusnak; 10-01-2010 at 12:43 PM.. |

They are quite instructive - easy to see the difference in the ball cage outer ring from one side (solid lip) to other side (flared lip). Given that the ball cage EXPLODED in my rebuilt shaft I want to be sure to get this right.
Did these come with any instructions on what side faced the driveshaft?

It looks like Warren's manual suggests the tapered side goes toward the axle, but I could be wrong. Like I said, I've flipped them around and the CVs have lasted 50K miles so far without any noticable wear. In fact, on the right side they are still quite tight.
I did noticed that the left side had pitting, but this was on both CVs. On Rennlist another person had the same thing. I am wondering if this is due to heat from the cat on the left side causing the grease to break down quicker. Also, it seems the consensus now is to put cv boot clamps on all 4 small ends of the cv boots. |
