ok, so I have an update on mine. Today I jacked her up and had a look underneath. The exhaust looked like it was hanging pretty close to chassy and diff and it moved a lot (up and down). The mechanic actually told me that the exhaust had been checked and there was no prob? In his defence, it did suddenly start knocking again after a trip to the coast. Anyway, I cable tied the rear muffler and the centre muffler tighter upwards for less movement. Second thing I saw was the bottom of both shock absorbers had small damage where a protruding bolt was very close when jacked up must have been hitting constantly whilst driving. I taped some soft rubber foam between the gap. Now when I drive her there is absolutely NO knocking at all. I will obviously look at more permanent solutions in the future, but in the interim they should hold up and continue to work, The handbrake cable theory sounds plauisble too because when mine WAS kocking, I could feel the vibrations through the handbrake although I did not touch my handbrake and the knock is gone... Hope this solves it for you.

I have similar thing in my 07 bf f6 sedan. It's lowered with adjustable coilovers and I have had everything checked and apparently all the bushes etc are fine. I have a squishy squeek sound when the car goes over every bump (apparently that's rubber suspension bushes after you have lowered car?) but I also have a metal on metal knock sounds which is really loud, constant as I'm driving and I can feel through the handbrake and through the floor above the driveline area like it vibrates through the car. Maybe mine is exhaust??? I don;t know though because it just happened all of a sudden and I'd already had exhaust mounts bent to stop it touching the diff last service... Also had diff and control blade bushes replaced. These weird noises in these cars are starting to annoy the sh*t out of me... I love falcons but I also hate them! Any further updates on yours???

Will do. I actually have two ideas after some further research. a) Could be wheel bearings since I have lost traction on more than a few occasions and done a drift day. I will get them looked at when changing the bushes. b) Could be the new tyres. I have kumho ecstas which I have been told are good but noisy. SHould be getting things done in the next couple of weeks so stay tuned.

Hi guys, I'm hoping this is a brakes issue or something related. Car is 2007 BF2 typhoon with 40,000km. Just recently I've started noticing a groning/droning noise (don't laugh at my explanation lol) which echoes through the car every so often whilst slowing down about approx 10% of the time. The majority of the time is under brakes at lower speeds when coming to a halt, however, it is sometimes apparent whilst slowing down without applying brakes which worries me. Sounds like it comes from the rear end. For your info, my rear end bushes are gone and I'm replacing them in the next few weeks. There is no issues accelerating or any other driveline issue evident other than the diff clunk due to bushes. Brakes look good. Any ideas? Cheers!

Thanks guys. Intreresting points from both sides. I might just be safe rather than sorry and wait untill I am ready to retune until I go bolting more performance parts on. Cheers Henz, I didn't know that the dyno can overstate the power figures.

Yes, unless the figures on the chart lie... They did 3 tunes, the top two both over 300rwkw. See attached image. The air/fuel ratios are good too. Extreme Street Performance in Queanbeyan NSW performed the tune. Grant does plenty xr and typhoons and the car has no spikes or issues to report after running this power for approx 4,000kms. So the consensus is a retune. Cheers guys, I will definitely consider this prior to making any more mods.

Hi Guys, My BF2 F6 is currently running standard intercooler and piping. The car has been flashed with the stock cooler/exhaust so I was wondering if I replace the standard intercooler with a bolt on larger core intercooler (stock piping) would I need a retune or will the computer learn it? From my limited knowledge I'd think not because its a variable that is regulalrly controlled by the outdoor temperature anyway. Just wanted to double check. Also, what if I added a dump pipe and high flow cat to the equation? I've been running considerably high power for some time now (at 323rwkw) with just larger injectors and want to cool things down and increase flow etc so that I don't lose out on hot days but don't have the bank balance to go all out thanks to upcoming replacement of some dead rear end bushes... :( Your help would be appreciated! Cheers!

No, its an auto. Extreme Street Performance in Queanbeyan. They have tuned a lot of these and have some tricks to make good reliable power on stock set ups that comes on nicely. Question, will the fitment of a bigger aftermarket intercooler, dump pipe and high flow cat always = need for new tune or is the ecu capable of learning the increased ability to breathe?

My BF2 typhoon made 323rwkw with just k&n panel filter, injectors and tune. Also had a gearbox tune done. Everything else is stock, including cat. Boost comes on nicely so far far so good.

Yeah, 100%. I was driving around last night and today and listening carefully and there's a click now most of the time when gears change. I don't recall hearing this before other than when I used to put it into reverse, once it engages gear. The other weird clinging noise has not reapeared since Friday night after driving it hard. Hoping that this is just a normal weird ford noise. Bloody fords, always doing some weird sh*t to make you worry!

Cheers, although that's an odd diagnosis... where's your's coming from, front or rear? Mine sounds like it's coming from the front half of the car. I said it sound like a metalic noise but now that I think of it, it's more like a clink similar to when you drag a cermaic tile or tap it against the ground. I looked up a youtube video for clunking axle and it sounds nothing like what I can hear. The thing that worries me is that it's on take off and change from 1st to 2nd (although only occasionaly).

Hi guys, Ive been searching the driveline threads but can't seem to find what I am looking for. I'm basically new to this even though I joined a long tie ago (sold the old xr6t ages ago and just bought typhoon). I own a 2007 BF2 typhoon with the ZF6 auto. It has 38,000kms and have had the ZF tune for approx 2000kms (325rwkw). Just like most others, I have the same diff bush thud issues and alos experience the delayed downshift to 1st gear when going up driveway or rolling to a stop and accelerating just before I stop. These are annoying issues but I have adjusted my driving style to suit. The issue I'd like to raise is an odd clink, almost light metalic type sound that is occasionally noticeable when moderately accelerating from a stationary position and sometimes heard when shift from 1st to 2nd gear is made. Yesterday after giving the car a bit of a hard with a full car load taking some guys to a formal and doing a few o-100km/h high rpm shifts and a burnout in manual mode it was more prevalent. Has anyone experienced this? I don't know what it is, there I no whining noises or anything like that. The guys at ESP performance said that the car was one of the best condition they've had in the shop and was very smooth and like new so I doubt I could have done any severe damage in 2000kms as I don't always drive it hard. Cheers, Zeljko

Thanks mate Yeah, CV's weren't something that I thought about much until it just happened. Apparently mine went because my car is so low at the back , and this caused unnnecessary stress on the components (ball cage etc). Theres a few threads on the site regarding stronger CV's that would be worth a read. Of the top of my head I only know the power is 325rwkw. Not sure on torque. Power curve is pretty rapid though.

Rebuilt the T5. I found out that it was a clip that broke that caused me to lose 5th, and apparently the box was in really good condition. They seem to think that the power had nothing to do with it even though they shouldn't be able to cope that power! Couldn't afford the T56, anyways, I'm still selling the car.

Thanks guys, Will do. I have a mate whos a mechanic coming to have a look this arvo and will probably fix it this week. I need it back for Bathurst!!! lol! Unless it's something more major, I should be right!
