Title: coupe 2.0 drive shaft spacer on 1977 Post by: mantagtj1981 on September 16, 2019, 09:08:12 PM im in the middle of a restoration 1977 mk2 2.0 coupe manual, i noticed on one side driveshaft there was a 5.5mm thick alloy spacer which seemed to i think take up slack between the outer cv joint and the shaft .
having checked the drive shafts are same length infact , so i cant see why you need this spacer it looks like someones fitted it . infact i cannot get the small spring round clip to sit behind the cv joint with the spacer fitted . has anyone noticed this small spacer on there cars? i m sure that perhaps both sides should have a small spacer to take the slack up.

It’s is a spring steel washer to provide preload to prevent the joint ‘chattering’ on the shaft during rotation.
To fit the circlip you will have to apply a little downward force to overcome the preload the spacer is creating. It has to be like that or eventually there will be premature wear on the driveshaft splines/joint or both.

When you pull the joint off of the shaft the preload washer often stays in the old boot hidden in the grease and gets thrown away unknowingly.
I’ve only ever seen curved spring steel washers used in beta/thema/croma/monte driveshafts but I guess there can be other types.

And that's to sit over the spring circlip to keep it in the groove whilst you insert the shaft into the outer CV joint?
