Synergie recurring problem

[citronut]

when we got my daughters synergie it had a loose N/S front swivel pin,
which we ended up fitting a second hand hub that seemed to be ok and got it through the MOT,

flippin things gone loose again, seems to be a common fault on these,

so apart from welding the hub to the swivel pin what is the long term fix

[Stewart(oily)]

Is that the lower balljoint ? is it the non taper type with a pinchbolt ? a la ZX ? If so I would be quite tempted to buy a nice new strong bolt and tighten to four white knuckles.

not bought a nice new strong bolt yet, but did give it a bit more with my 2 foot knuckle bar

trouble is if you give it to much welly you could fracture the cast iron hub

[citronut]

nudge nudge

has anyone ever permanently fixed this fault,

short of welding the BBBBB ball joint to the hub

I am probably wrong but i think there may have been the possibility of 2 different ball joint pins. The pinch bolt as far as I remember is an M10 8.8 bolt. If you want to be able to really welly it up replace it with a 12.9 bolt. They usually come in socket cap format.

thanks for that,
but i would not feel happy straining the case iron hub/pinch clamp to much, as it then risks fracturing it,

bin thinking why it keeps recurring,
it might be the lower swivel has worn into its cup/seat to much, so struggles to rotate with the steering being turned,

any more suggestions
