If a leak it is large hence it struggles to lift to level 1 and 2 after that the leak(hole) closes and it will keep air ok.

let us know what it does at level 1 in jack mode,

I drilled out the dreaded pinch bolt last year on that side to replace a CV joint, so the operation should go pretty easy (removing the pinch bolt that is).

Is Arnott the best place to buy just one air spring? I just want original equipment type performance.

Thanks,
Doug
