LOUD CLUNK noise from rear when pulling off, any ideas?

Is the handbrake integral with the caliper or are they separate shoes? My Celica was similar but went when I changed the discs and rebuilt the mechanism and new shoes.

Anyway this thread is a little pointless. It is a brand new car so let fix or repair daily deal with it ;).
 
I guess Ford are likely to wash their hands of it considering the problem is almost definitely caused by the modification work done to it.

Not only that but they aint gonna have much more of a clue, easier to just tighten everything down myself and if it still does it and I am confident its the differential itself well then they can fix it.

But I am feeling it is as suggested a lose bolt allowing either subframe or differential movement.
 
I'd check the driveshaft nut/bolt that holds it in the hub. Focus st's are known to click like that and ford glue the shaft in place to stop the noise. Replace the nut or bolt and torque up to see if that cures it.

Yep Fuzz suggested I check this, when I take it mates garage tomorrow we can check all these suggestions and if we find the issue will share what fixed it. :)
 
Too many things to really diagnose from a forum post, I would just start stripping stuff down until you find something loose/broken. I once had a similar noise from a brake pad.

The 350Z suffers from this, prop shafts - sounds as though it could be the same, especially if you've been tinkering :p

The Mustang as standard has driveline noise and thuds, just part of the design.

This is something other than the norm gonna check:
- Subframe bolts (Feeling this is main culprit)
- Caliper bolts
- Hub bolts
- Differential bolts
- Rear ARB
- Rear pads


In normal driving it hardly ever does it, on the rare occaison it might do it when on power over some rough bumpy roads, just a solid clunk which is making me feel subframe bolt or when pulling off sometimes or easy it moving forward and backward and letting clutch out quick.

So I feel its a bolt lose or not torqued properly as whatever it is does not seem to be getting loser if makes sense. Main thing is car drives fine so its not resulted in having to park it can still use it daily but taking it garage today. :)
 
If your prop has ever been removed whilst doing the rear subframe work, make sure the angle of it is to factory specs.

If not my money is on subframe being loose and the diff hitting the chassis from the extra movement it now has.
 
I had an intermittent thud problem like this on my Fiesta ST when pulling away, slowing down, going over bumps etc. Spent ages trying to find it but nothing. Turned out to be one of the front brakes :/

Also found a loose rear engine mount while investigating though!

Ford are quite good at not tightening bolts and hoses properly it seems. I've seen quite a few posts on owners club forums from people who have found stuff hanging off new cars, boost hoses coming out etc :P

Hi there


Took it to local Jaguar specialist, went forward, backward, CLUNK! They were like we know that sound, its your hub bolt (big one in centre 32mm socket) and the splines moving. Common problem on the XF supposedly which had a recall issued for it.

Anyway they whipped rear wheels of and check to see if hub bolt was lose, it was not but it did tighten a further 5-6 degrees on each side.

Clunk now seems to be gone. :)


They said if it comes back what Jaguar did was to glue the shafts using loctite into the hubs to stop the random clunking, about 1hr work per side but they said Ford would sort it under warranty, so if comes back just take to Ford.

Glad was an easy fix, drive home was incredible fun, race mode engaged. :D
