Well I had my truck in for a new ring gear and pinion because it was howling pretty good at highway speeds. They changed the gears and now I have a gigantic vibrator!! It shakes fairly severly between 60kph and 85kph, enough to shake the cd's and change around real good. Now just waiting to see what happens, can't get any answers from them at the moment. I hate to say it but Ford is on strike three with me now!

 

it might not have to do with the gear change, it could be that they didnt bolt the driveshaft back up in the phase it was originally in. It can only be 1 of 4 positions, so they should be able to get it back where it was.

 

Thanks, I am going to mention that to them and see if they will try that.

 

had the same issue after the clutch pack change...after third time back,they had to put in "spacer kit" . but is finally ok.good luck !

 

It's good to hear that eventually they can fix it, I talk to them today to see what they will do.
