I have taken it to 2 ford dealers and both have advised that is has approx 45mm of backlash and that anything under 50 is acceptable. It also is a little noisy around the 100 mark as in whining. The car has only done 58,000ks Does anyone know a dealer that I might have some luck with getting it overhauled or replaced. Link to comment Share on other sites More sharing options...

I had the same issue as yu and could not get the dealer to fix it as it was not over 50mm of freeplay. I then went in to complain about diff whine... well what do yo know.. they replace the diff for diff whine but not for the clunk that your talking about.. so what im trying to say is complain about diff whine and how its making you mad Link to comment Share on other sites More sharing options...

Movement in the driveline as a whole can be a combination of a loose clutch hub right through to CV joint wear and only qualified driveline experts can tell the differance.

We want to use the factory auto transmission cooler so factory brackets and lines will be used as well. Mal Link to comment Share on other sites More sharing options...

We have found that the centre bearing is positioned to high and if you get the car or ute on a hoist and have a close look at the height of the centre bearing and then take a look at the BCD coupling (rubber drive coupling) you will see that the rubber is stressed. By spacing the centre bearing down (normally by about 6 to 8 mm) the stress is relieved on the coupling and NO more vibe. Mal Link to comment Share on other sites More sharing options...
Adam Here since the start...
