Hughsie Posted March 27, 2014 Share Posted March 27, 2014 Hey guys, I have just converted my mk2 escort from auto to manual. Took it for the first drive and I had some serious vibrations around 2-3 thousand revs. So I took the drive shaft down to be balanced and had all of the universal joints replaced while they were at it. Next drive and I still have vibration. Exactly the same. Any ideas? The only thing I can think of is maybe the gearbox isn't centered as I had a new cross member fabricated. Otherwise, maybe it's the gearbox? Help! Quote Link to comment Share on other sites More sharing options...
AllTorque Posted March 27, 2014 Share Posted March 27, 2014 It could be a pinion angle problem. Have a look here: //oldschool.co.nz/index.php?/topic/38050-pinion-angle/ Quote Link to comment Share on other sites More sharing options...
shaneo Posted March 27, 2014 Share Posted March 27, 2014 I have had this issue for a long time hard to find what it is. Was the gear box from a running car? Quote Link to comment Share on other sites More sharing options...
downtrail Posted March 27, 2014 Share Posted March 27, 2014 do they run a spigot bearing or bush in the end of the crank or flywheel? I forgot to put one in when doing an auto manual conversion once vibration like you wouldn't believe! Quote Link to comment Share on other sites More sharing options...
cletus Posted March 27, 2014 Share Posted March 27, 2014 is the vibration only when you are driving? or if you put it in neutral and rev it does it do it? Quote Link to comment Share on other sites More sharing options...
tortron Posted March 27, 2014 Share Posted March 27, 2014 i had a dud new U Joint go in the truck, double check? That or start thinking flywheel (should do it in neutral) or clutch/gearbox all the bolts done up in the drive train? how about the wheels, i had a hell of a vibration once, turned out the wheel nuts had backed off Quote Link to comment Share on other sites More sharing options...
Hughsie Posted March 28, 2014 Author Share Posted March 28, 2014 Vibration is only when driving. The spigot bearing is in and everything's nice and tight. Gearbox feels nice with clean changes. I think you're on the money ALLTorque. I had a guy come to have a look tonight and that was the first thing he picked up on. Because we used the auto crossmember, it dropped the rear of the gearbox down about an inch. So we're going to make up a bush for the crossmember and see how that goes. Thanks for the tips! 1 Quote Link to comment Share on other sites More sharing options...
