The lean is getting bad. I had the same issue with an explorer and replaced the leafs with new aftermarket ones and it leveled right out.

They say because of the gas tank being on one side, the drivers side leaf takes more abuse and wears out quicker.
However it happens, it is what it is I need to fix it.

Trying to get used springs is diffecult to get a perfect match as one vehical may take more abuse than the other.

Tortion bar adjustment will help the front end, but doesn't eliminate the worn leaf in the rear.

The problem I'm having is locating OEM leafs for a 2000. they only seem to go up to 94.

I didn't find a spacer made for this specific use, I would rather fix it the right way if possible. I suppose I could fabricate one or just ad a leaf to that one side.
