Hey guys. I'm having harmonic driveline vibrations in my '07 Manual typhoon. But first a run down on the history of the car. Bought in 2011 with only 17 000 ks, and had stuffed diff bushes from the get go, that was fixed firstly by ford. They lasted about 5000ks and were pooched. The next diff bush endeavour was done at an independent shop and all three bushes were replaced with nolathane polyurathane (or however you spell that) bushes. Now.. this uncovered the first vibration! turns out the tailshaft was out of balance quite badly, and wasn't noticed previously due to the bushes soaking up all the vibration, and was noticed after due to the solid bushes.. (also explains why I went through the factory bushes so quickly!) So that was fixed and my car was the best its ever been. After about 10000 ks of worry free motoring I went chasing horsepower. Some blingy bits, some supporting mods, a clutch and a trip to Monsta Torque and my F6 was comfortably producing 384rwkw. At this stage I started to have wheel hop issues. A few really bad 1st gear axle tramp launches at the drags and I figured something wasn't right, shortly after that I snapped a halfshaft.. Due to being recently back from an overseas working holiday and en-employed I just chucked a high k's second hand half shaft in it so I could drive it again. whilst doing this I noticed the the diff bush housing on the k frame was tearing!! MY POOR BABY! Also noticed was the beginning of this latest vibration that I'm having. I was convinced it was something to do with the rooted cradle, or a sh*tty CV from the high k's half shaft, or the other halfshaft about to let go as well. So after getting some money together again I forked out and went silly. Coilovers all round, swaybars front and rear, IMS twin bush diff hat and a matched pair of low k's halfshafts. All done in the back shed by yours truly. I thought for sure this will solve my wheel hop and vibration problems for sure! AND IT DID! solve the wheelhop issue... but not the vibration! I was convinced it has to be tailshaft as everything else has been changed! (diff was inspected and was fine). But then when I was driving it today I noticed something. you see before hand, I thought the vibration was totally linear with ground speed, MOST prominent with downshifting, engine breaking and seemingly consistent around 100-120kph. But TODAY I noticed around 110 in 5th gear the vibration is quite loud/prominent, but shift to 4th or 6th with the same load and it almost disappears... So now I'm thinking I have a on-its-way-out T56 that's causing the suspected vibration.. Thoughts? Sorry about the Novel just trying to supply as much info as I can, I appreciate any input or suggestions! P.S If anyone's been thinking of doing the IMS diff hat, DO IT, its so worth it. Cheers.

hey guys! My wife's v6 terri has done just over 180,000 kms and its vibrating and shuddering worst at 60-80 kms around 1500-1700 revs. its shuddering sending the rev count low losing power, then spiratically goes high again to regain it. This is the first real problem we have had with it. ive previously changed transmission oil and filter, engine oil and filter and brake pads. I know the drive belt does need changing. Any ideas? I'm hoping a mechanic won't rip me off to much if I get some ideas or if easy enough I can do it. Thanks Sam

Hi, Looks like a lot of people having the problems was having until now after just going back and back until they here'd what I was hearing and feeling. If anyone has some info. I might need please feel free to as I'm get a little confused with it all. I dropped my FG XR6T 2012 30k km of at ford service to have them look into some clunk creeks and vibration I've notice, they have had it for 3 days and Im picking it up today. So far they have told me that they have done a wheel alignment, check and tighten the handbrake and machined the disk but I'll have to go back in 1.5 to 2 weeks as they have ordered in from Melbourne and new tailsharft and diff bushes. All under warranty as I paid for the hand break and alignment last time I dropped the car of. So what do I need to know when I pick up the car today. And is there something I sould get them to check or do when I take it back to get the tailsharft and bushes done? Also so can someone tell me how many diff bushes there are? Thanks
