Assuming you had your WDH set up before, for proper weight distribution, then all you should need to do is get the WD head/ball back to the height it was before.
The typical answer when something needs to be adjusted, is that you have to go thru the measurements again. But in this case, I don't think that applies. Of course, it would not hurt to check your front wheel well measurements again...
