Thought I would go deeply !! into why one side of my 2015 Journey Outback has a lot more negative camber than the other.After an hour amongst the black ants I found the rear cross arm of the A arm was not parallel in a horizontal line to the front cross arm with the bushes.(other side OK)About 3/16 out ,ie up on the outside hub end.Had it wheel aligned by a truck alignment place who said just about every Jayco with this JTech suspension causes him a problem.May take A arm out and see if it can be straightened

Not like you can give it bend with a press like a beam, why didn't they fit an off centre bolt adjuster on the arm pivot points be able to sort camber and toe easy enough then.
The knee suspension on my Coronal has no adjustment, spring may sag after 80K km and tyre will scrub, so reset springs or buy new ones...
Following your exploits with this as its of great interest.

Been talking to a guy I know at Pedders re making a camber off centre bolt kit .Not to keen as I think Pedders make the springs and supply shocks etc for Jayco.JTech Do not think it would take too much to bring the A arm back.Just time to pull a part etc.in between use.

Is the tyre wearing on one side? I would have thought a degree or 2 of camber would not be an issue - my ute had over a degree for a year before I got around to adjusting it...
My 2015 jtech suspension only has toe adjustment but I thought they quickly added camber. Doing toe adjustments is very easy at home - just need a $5, 1m long steel craft ruler and a length of straight aluminum angle from bunnings. Lay the straight edge across the tyre wall about chassis height and measure each side to the chassis rail. + or - 1mm is fine. I checked my adjustment with a laser aligner and it was spot on.

I suppose looking around various vehicles with a tape measure to find a bolt of similar size could be a mission then procure a few to mod, wouldn't be too hard as they would be using off the shelf bolt and bushes anyway ......................possibly have to make new hangers though, be a good project, not difficult just fiddly.....

I once made a slide rule of the large variety out of 1/2" square timber with an old tape measure stuck to it, was perfect for doing alignments on my old 4x4's, front wheels sitting on lino squares on smooth concrete so they would slip.......................no rock hopping now so hardly need to do it.

Can you elongate the inner bracket bolt holes (upwards I guess) then tack weld washers on each side. IE: replicate the outer toe adjustment bracket slot but for camber?

For what its worth, my 20.63 has only 1 of the 3 Jtec axles parallel to the ground, the wonky 3 being various degrees out of tilt one bad enough i took it back to Jayco fearing a imminent catastrophic failure. To my horror 9 of the 10 new Jtec vans on display were the same and a few worse. My caster is fine, my van has now done over 50k km; 30k km with the current tyres all km's with the leaning wheels. I dont have any obvious adverse tread wear.
