Hi mate.
Undo the clamps and bolts, slowly drop it down on a jack with a block of wood.
You would only have to drop the subframe enough to get the bar through, then you can slide the bush into the location after, from the side. I was really unsure of how much I could slacken subframe bolts without them dropping out lol
I fitted poly bushes to mine, which did not slide in well, even with shed loads of copper grease.. Rubber bushes maybe easier to fit than poly.
Go for it bud
