Fabric joint

[Colin Reed]

I am sure this has been discussed before, but I am looking for info on what I may have done wrong on fitting.
This joint has only done about 500klms. Have I had the bolts too tight or loose? Are there different qualities? The drive shaft appears to be straight.

Hi Simon, When fitting a new one make sure the hex on the bolt is sitting flush against the riveted plate and not on the rivet heads this goes for both sides as it will put a twist in the fabric and produce vibration 
I would be inclined to fit the same type as it does look like external damage
This is not a Criticism just an observation from the photo
all the best colin
