Clunk From Rear Of The Car

[AlexCim]

From this thread - http://www.skylinesaustralia.com/forums/in...opic=92969&st=0

So what I did was this.

Jacked the car up on 4 stands, removed the rear wheels and...

- When rotating the drive shaft from next to the mid muffler, only one wheel turned (one warped brake disk causing slight rubbing)(on another note, could this attribute to poor fuel economy?) but there was basically no slack at all. I also used one hand and held the hub softly and then turned the tailshaft to see what the delay was, almost instant.

- Then i looked forward, there was a 1-2cm turn distance delay from turning the tailshaft to when the front wheels started to turn, could this be an issue?

- The ammount of free movement in the uni joint was 1mm, MAYBE 2mm. It was almost nothing.

So then I got thinking

- I went around to the drive side (kinda where the noise comes from) and i pulled the axle IN towards the car (ie away from the hub). Let it go softly and it made a clunk clunck clunck noise, as if it wasnt greased or something. Tried the same on the other side and got much more a muffled thud thud thud noise. Can someone try this on their car and tell me if when the axle is pulled away from the hub and let go it clunks or thuds?

- Didnt do the fronts, but i tried to move the front axles and they wouldnt budge. So i ticked them off and went on my way

- Also, I got someone else to turn the other side wheel in the same direction as me at the same time as brad suggested about it being open. There was again, almost no slack between when we turned it and when the tailshaft started moving

- Oh and, i sat in the car and got my friend to pull the axle in and let it go/repeat, it sounded almost identical to what i was hearing when turning tight corners. THOUGH, dont let that sway you. I am sure heaps of things sound the same.

- Turning the tailshaft back and forth more quickly didnt produce any results either.

It was good to get under the car and play around, missed being under there

Oh, Also, here is something to think about.

The noise only comes when I am doing slow/tight turns, this means that there would be weight on/off one/more wheels. I am leaning towards the idea of it being the CV joints in the rear driverside wheel. Best to probably just replace all of them at once if need be no?? (as in, they are the cause)

Also, the reason that i tied in SK's suspension kit with the noise (its different to the clapping i was telling you about SK) was probably because lowering the car caused the extended wear of the joint to become more audible. Specially with the subframe lock kit too! And the only thing i had changed, apart from the fact that i ignored ride height, was the suspension, so i thought it was to blame!

Am I on to something here? Anyone else got any other ideas?

I was sliding in and out the axle (at the top of the pic)

It was making a clunk inside the hub somewhere, here is a picture of the hub from FAST

i've got the same problem as you guys, usually happens at take off and 2nd gear when turning. if someone knows how to fix this, help would be appreciated.
