Click-Click From Right Rear Wheelend

Hello all-
A bit frustrated here, I just got my car (78 SC) back on the road after redoing the spring plate bushings and an alignment, and I now have a strange clicking coming from the right rear corner.

The sound is a click-click (in quick cadence) that occurs once per wheel revolution, in forward and reverse. I jacked up the rear end and spun the wheels by hand and there was no clicking. I ran my hand all around the inside of the wheel to see if anything was rubbing on the caliper or something, nothing. I push and pulled on the wheel to check the bearings and there is no perceptable play. Once it was down I thought to check the axle shaft. I was not able to feel any freeplay (torsionally or along the centerline) in the axleshafts.
I drove it up and down the street afterward, and the noise was still there.

The only thing I can think of: when I changed out the spring plate bushings, I did not remove/unbolt the axleshafts from the stub axle. Could I have unduly stressed the CVs by not doing so?

I did not notice the noise when driving to the shop that did the alignment, nor on the drive home. Someone pointed it out to me in the parking lot of the video store after a 40 mile trip on the highway. Of course, now I can't help but notice it.

Puzzled in MI,
Chris

Sounds like the CV joint to me.

Hi Chris,

This is the most amazing coincidence. I spent the whole winter rebuilding the chassis, including new spring plate bushes etc. I lowered the height to 24.5 rear and 25 front and then drove it down to a Porsche specialist for a 4 wheel alignment. The car felt pretty good on the 15 mile drive to the garage. The garage phoned me up to tell me the work was complete and did I know my RHS CV was clicking. I said I didn't, but that because it was the only part I hadn't replaced in the rebuild I would do it myself. Well, when I collected the car and drove it home, sure as eggs there was a load clicking on moderately hard right turns. I thought like you that the CV may have ben stressed when I ran the engine for short periods with the suspension disconnected. Well, to cut a long story short I replaced the CVs and the clicking is still there. I am racking my brains too what is the cause. It almost sounds like something loose underneath. The other coincidence is we are both from Michigan. Spooky! Where did you take yours for the alignment?

If you have solved the problem, please post the solution.
