Brendan Donating Members 19 Member For: 17y 9m 2d Gender: Male Location: Central QLD Posted 11/06/12 08:28 AM Share Posted 11/06/12 08:28 AM So have spent the last 6 hrs going through every post in driveline forum which may relate to my problem, and also smashed google, but can not work out what might be the problem with my car.Have an 06 BF XR6 T with a light vibration coming from somewhere in the rear of the car. It does not start until about 95km/h, but does not start straight away, e.g. get onto the motorway and accelerate to 100km/h and after maybe 15 - 30 seconds it starts of lightly and slowly progresses to a very noticeable vibration. Interestingly, at about 120km/h it goes away regardless of how long I have been driving.This problem started after a 100km drive from central qld to brizzie.There is nothing coming through the steering wheel but does somewhat through the gear stick and seat.So far I have had the following done from advice trying to fix the problem.new mags, as 3 of them where bucklednew tyresNew pedders suspensionPark break adjustedAlso take into account, before the vibration started I had the diff bushes replaced because they where f'd, as they do (vibration didnt start straight after this though)... which bought up lots and lots of continuous clunks at low speeds which was the diff f'd which has also been completely rebuilt, but as I couldn't afford the rebuild straight away, it was carried out after I drove to brisbane, so this problem arose while the diff was f'd, but remains after the diff rebuild.This is professionals (but not ford service) giving me this advice and this f'n vibration is still there, and dont know where to go from here.I just want to gather some peoples opinions before I bite the bullet and take it to ford and say I don't want it back until its fixed.Thanks for your help in advance! ...if you can lol.

Or could they fall off, even? Coz im pretty sure the problem wasn't their when I started my trip but when I got on the smooth highways of brissie it was really noticeable.

Also if the diff has been rebuilt the tailshaft will need on car balancing... I would get ford to balance your tailshaft... Removing and balancing at a driveline shop wont work either... Not sure if anyone bar ford has the correct equipment to balance our tailshafts, iv done heaps and its quite an involved process Edited 11/06/12 09:07 AM by bionicxr6t05 2 Link to comment Share on other sites More sharing options...

Thanks heaps mate Link to comment Share on other sites More sharing options...

The cost involved is labour+ weights which are pretty cheap, best case scenario should get away under 150 bucks... Link to comment Share on other sites More sharing options...

Ford mechanic took it for a drive. Told me what it was as soon as the problem came up. Had it fixed the next day. Tail shaft balance. Link to comment Share on other sites More sharing options...
