I am running an S-15 4X4 front end and I keep getting a vibration from the C.V. shafts. I install new ones, and a month later, they vibrate yet again. Upon inspection, the side facing the diff carrier seems to be bulging. Warrantee is great, but I really would like to know if a better solution is out there.
Ha ha, you are a funny man!
It sounds like the axle is too tight lengthwise and binding up the joints. Like the shaft might be too long.
I know your ride height is a little lower with the SBC, maybe the shaft sits different now. I would shim the axle housing up and away a little to try and gain some distance. Another option would be disassembling the CV axle and having the outer flange turned to allow the axle to fit a bit farther into the hub. Or machine the backside of the hub to do the same.
Hey Grinder; that is the same thought I had so I took the shaft off at the diff and found that I had about an inch free play even when the hub was horizonal with the diff, so I doubt that is it.Quote:

Now, there is about a 1/4 inch room in the centre circle of the shaft where it mates to the diff. In other words, the mounting flange has about a 7 inch diameter which is recessed, and then there is a 5 inch circle which fits into the diff flange, however the center does not make contact with the diff, this is direct from OEM. So I am wondering if I made a 1/4 inch plate to try and put pressure on the center of the shaft housing so as to give it support, if that might be a good idea or a horrible idea. Me thinks bad.
