What did you use to seal them?

Search the archives and this forum. There are several threads on this topic. I filled the big gaps in my wheel wells with expanding foam, the smaller ones with caulk. No more water inside.

Used Dicor non-sag at the aluminum joint to the vinyl flooring (if you have it on yours). Then repainted the wheel wells and sealed the edge joints of the flooring and aluminum planks with 3m undercoating.

After filling the larger gaps there's still a tendency over time, weather, heat and surface movement for cracks to appear in the caulk. Taking a page out of why drywall seams are taped, I now embed fiberglass drywall tape or even fiberglass cloth in whatever crack sealer is being used. GK

We sealed our wheel wells with a spray on sealer.  Still noticed a little water when travelling during heavy rains, turned out to be water coming in where the water lines penetrated the floor near the water heater. We cleaned out the old spray foam sealer and carefully spray foamed the area again. This fixed the water problems.
