Do I have to use the dust cover off the stock flange on my new Yoke?

I have already installed my new drive shafts and I did not use the dust cover off the rear flange on the new yoke.

I have seen recently where some folks are using it, is this a must?

thanks

 

No, you don't use it, in fact it'll usually rattle if you do

 

yup, what mkjeep said

 

sweet... then i dont have to worry about it.....

I didnt think you did but have read a few posts where some folks did.
