Leveling Jack Problem 1998 30' Land Yacht

[gcox2204]

Looking for help with this one. the Land Yacht has Big Foot Brand by Hydra leveling jack system. We have had the unit for a couple of years without major problems. However on a trip to Mass. from PA, the right front pump system for the right front jack broke (How I don't know) we did hear a loud bang and I looked to see if we hit anything and nothing was in the road, the coach continued to handle OK, until I made a right turn off the toll road. Ultimately I found out the pump system for the jack is mounted inside the right front wheel well. After the bang, the tire now rubs against the unit. I replaced the pump assembly via a local RV dealer, and they reported nothing else wrong.

The wheel has since continued to rub against the pump unit, and of course it now no longer works. The only conclusion I have is the front end has dropped, as the tire never rubbed before, though it was probably very close. I checked the springs and undercarriage as best as I could and nothing appears broke. The air bags inside the coil springs seem to be inflated, but my knowledge stops there. Any Ideas on what is wrong??
