Vibration

[northyorkspaul]

Hello all......just joined the forum,Paul north yorkshire...I have been restoring a minor 1969 reg,over the last 6 years haha.getting there now but I notice a vibration ar around 50 mph this is slightly worse on the overrun.....someone said it may be the diff,I am going to check the prop ujs but dont think they are that bad.Does anyone have any thoughts?.....just thinking someone may have an idea!......thanks.P.

Welcome to the forum - start with wheel balance! Then look for worn u/js on the prop shaft and some have found the rear axle 'perches' that the rear springs fit to - have rotted badly allowing the axle to rotate so the prop shaft can't run as it should.

Also check the prop / diff flange for run out.....
