Sorry to revive my own thread but put new shocks in today and the clunk is now worse. Turns out I have to get diff bushes a lot sooner than I wanted too so they're going in next week and see how that goes!!

Okay well I had my rear muffler cut out and replaced with a straight pipe 2 days ago and I swear the clunk disappeared! It definitely was too much of a thud to sound like the exhaust but it is possible! But its also possible that the exhaust note was hiding the clunk so I can't hear it.

But more to the fact I had the diff bushes replaced this morning with Superpro and I found the roughest piece of road I could find and not a single sound! Problem solved lol.

So after all this I would suggest for people to firstly check the exhaust thoroughly! Ford, Pedders and myself all couldn't identify the knock and we all ruled out the exhaust but check it first!

Then after that do your diff bushes! Leave your control blade bushes and shocks for later (unless you want to do it all in one go) because they weren't the problem.

^^ Correct in the short term, not so much in the long term. As senna said, by replacing the centre with a super pro the stiffer bush puts more pressure on the side ones and stuff them, then you have to go and change them anyway so double labour.

When I got mine done I paid $240 for the 3 bushes and then $380 for labour (at ford of all places lol). Cheaper than I thought but still not the cheapest job. But UWNTM3 work out if you need your rear camber adjusted at all because if you do then the only available camber adjustments on the market require having the diff cradle dropped to replace the left side control arm. When you go back to Wholesale suspension talk to them about all this. It's ALOT easier to do camber kits and diff bushes at once or you'll double up on labour

I have a pretty vicious clunk from the driveline when coming off the accelerator after hard acceleration, assuming diff bushes but the zf 6 speed is not anywhere near as smooth as I expected....

Great thread gents very helpful will book into pedders
