Ok a bit of a update with more photos (Sorry photo heavy)
The arm was on the correct way, here is a photo of the arm on the floor
I put the arm back on but this time with jack stands under the lower A-arms and lowered the lift so the weight was fully on the arms IE ride height. There just shy of 3" between the bump stop does this look right with a 1.5" drop spring.
Here is another photo of it sitting on the jack stands
Ok moving forward, the truck is on its jack stands, so now i tighten up just the clamps on the lower arms both sides. You can see how the sway bar wants to sit, there is around a 8-9" gap from it meeting the centre brackets, i have taken some of the strane up here with a strap.
I used the strap to pull the bar into place so i could get the nuts on the bolts and tighten them up. So now we have the sway bar fitted and still on the jack stands, the of the end of the bar is not parallel to the A-arm and it is stressing the outer / rear of the bush, you can just make out the gap at the bottom on the bush here.
As soon as i lift the truck off the jack stands and the arms move down just an inch the bushes pops right back out.
Here are some more photos of the bushes, clamps and brackets as requested.
So still not sure what the issue is, the sway bar just looks at the wrong angle, either the lower arm has got to go up more or the centre brackets have to come down more for it to work.
OR the sway bay has bee made wrong ? although it looks the same as the photo posted here.
