U Joints Or...?

All,

Currently tracking down the source of a clunking/clicking noise from the rear of my '75 spitfire 1500. Here's what I have found so far:

1) The sound DOES depend on speed, i;e faster speed = more rapid sound
2) I only hear the sound when decelerating

These points lead me to believe it is a UJ issue, however the sound does not seem to change as the car goes around a bend, as bad axle UJs would.

As shown in the pictures (hope I posted those correctly), each UJ has one snap ring that seems to be rubbing on the UJ, creating a shiny ring. Perhaps the experts of this forum could shed some light...

Thanks!

Might have to get a screw driver in by the u-joint and pry it around a little to check for movement. A joint on my axle was missing most all the needle bearings in a cap and I didn't even see it till I moved the axle while holding the yoke and noticed the movement.

I would say the chances are 10-1 it is the UJ

Thanks for the input, gentlemen. I'll see what I can find for movement with the screwdriver tomorrow AM.

If the bearing cap and the retainer clip are moving against each other you have an issue. There is no reason for them to move, in fact the bearing cap should be snug enough in the joint that it will not move.

I had a loud clicking sound when turning.I replaced the ujoints ,axle bearings,seals etc.Still clicked.Pulled the diff and found the spider gear thrust washers worn badly. I replaced the thrust washers and the clicking went away. the rear seemed quieter also. I have been unable to find these washers since.If anybody knows of a source for these washers please post them!

That bearing cap is locked on the cross and turning in the yoke, which is now junk. (bearing is supposed to be a light press fit in yoke)

Pretty sure SpitBits had the brass/bronze thrust washers

Thanks, I had missed that from #6, was trying to relate UJ cups to thrust washers, and coming up empty.
