#1 Slight clonk from back of car

Hi all
I get a slight clonk/knock when clutch engaged and drive is going to prop shaft pulling away in 1st and occasionally when I engage second I also get it.
It seems to happen when I stop and engage reverse too
It appears to be from the rear of the car
No clutch slip, gears engage easily, car drives well, no wobbles, prop shaft rear bolts to diff all tight, no rear brake noise, drive shafts bolted tight, wheels firmly knocked on
Any ideas??

Radius arm bushes(on the cups).
Pretty easy to do. The new cheap ones are crap!.

Interesting
I’ll check
The off side(right) just behind me has certainly been a little clonky since fitting!

As James mentioned, it's probably radius-arm bushings, but I would raise the rear of the car and look, wiggle and poke at everything. I once experienced some intermittent clunking in the rear of my '65, and it turned out to be a half-shaft U-joint bearing breaking up. I would have expected more drama from this, but it was just the occasional clunk.

Hi Moe
Thanks
I’ll have a good wiggle
It does sound a bit more like some slack is being taken up when I pull away from stationary either in forward or reverse

Hi i had the same problem it ended up being one of the driveshaft UJs no play could be found but when i dismantled the shafts i found the right hand inner joint had one cup that had collapsed no play could be felt on shaft when on the bench i had decided to replace them even though they were new when i bought the car 5 years ago
