After completing my wishbones, I have tried to assembling everything. I cannot seem to get enough angle between the top ball joint and and the Sierra upright mushroom insert when the suspension is down at its lowest point. Obviously as the suspenstion takes the weight, it will move up and will be ok, but I do not want the transit ball joint to, effectively, be the down stop for the suspension.

Has anyone come up against this before?

Is there a quick way round this, or have I cocked up on the design!


Any help appreciated. Thanks,

i had the same problem. the MK upper bone is pointed up at the end to combat this problem, but mine still 'bottomed out'. to aviod this, i let it droop, lifted it an inch, and then welded to shocker brackets in to stop it falling that low. Now the shock absorber is the ultimate droop stop.

RPS,

'Fraid you've cocked up on the design mate!

Joel is correct- the distance between the BJ holes on the Sierra upright is greater than that of the Cortina so the top wishbone has to angle 'up'. This isn't ideal anyway as you want the wishbones as parallel to the ground as possible at full car weight I believe.

I made my wishbones with the threaded tube pointing upwards- like the MK (and GTS if I recall correctly) wishbones.

if you look at the strut 'holder' on the sierra hub, you will see that its angled and not at 90 deg to the wheel.

you have to make your bones with the transit joint biased to suit that angle

take a look at pics of an indy, and you will see thats what they did.

the joint actually has quite a limited arc - and you may find that it is more restricted when you have steering on full lock

Bugger!!


I think I will come back to them later on when I have got the engine running. They could have been made better anyway, so I will now have the opportunity to get them right. All part of the learning curve I suppose.

Thanks,

never a wiser word spoken.
