Lean to the right

[PeterBo]

I have a RHS drive 1929 Phaeton and it has a significant lean to the right (drivers side) of about 1 inch lower body on the right. I have tried greasing front and rear springs, adjusting U bolt tension and order of tightening as described in other posts. The problem is a bit improved by doing these steps but not sufficiently. I now notice some contact between the right front wheel rubbing on the right side spare wheel well of the right fender!!

So, my question is, "Why can't I jack up the front of the car by the chassis and then release the front Spring shackles and the U bolts, remove the front Spring cluster and simple reverse it and re-insert (that is, the left side of the springs becomes the right side and vice versa)".

The attached image shows the lean.

Thanks, Peter
