Hey guys I have a 2003 Ba xr6t, with around about 360kw and 60,000kms.. I did the t56 conversion myself about a year ago and since then in the lower rpm range from about 1000 - 3000 rpm there is a vibration felt through the driveline... At first I though it could have been because I still have the old 2:75 diff gears.. But now It's sort of starting to annoy me lol.. Any1 else experience this with their car? I've heard from a few people that it's normal in the T56s but I just want to make sure..

Any help would be Greatly appreciated... Cheers Tam!

Tailshaft balanced?

im with worm..Sounds like the tailshaft needs balancing.. may need to go another turn around or get it balanced properly..Does it vibrate when you back off the power and roll..if so would be your tailshaft.

you need to work out whether it's related to engine speed or tailshaft speed for a start

Who does this guy think he is? ;-)

Oh sh*t

Sorry 3.75 gears lol typo error... Stuff 2.75 the thing would bloody move lol.. Yeh could be tailshaft I guess.. When I removed it I refitted it I marked it same position.. Nah doesn't do it rolling or when decelerating only under load in an gear say around 1000 rpm just near 3000rpm... The power is fine on the car still breaking traction in second and pulls away fine.... Any other suggestion on what to look for guys? cheers for that...

I`ve had the exact same problem with mine. . . My T56 was put in about 4 months ago and ever since had the same vibration you have in the same rev range. I have since removed the complete rear end and had it overhauled, I`ve also had a on car tailshaft balance done at ford, and still haven`t gotten rid of the vibration. The next thing to do is remone the box and send it back for warranty. . . I`ll keep you posted.

Farout really! Wow.. That vibration must b really pissibg u off lol, I'm really not keen on taking out the rear end Ay... Yeh gbox n flywheel area is the only other thing it could be I guess.. I wonder if others that had done the t56 conversion get it too... Because when I had the T5 in it didn't vibrate at all... yeh keep us posted thatll b great mate thanks..
