Leaning Truck ?

[mhicks]

My son's pickup is low on the passenger side. He has had it about a year and we made atrip to Arkansas a while back and he followed us and we followed him. We noticed that the passenger side of the truck is leaning. We measured from the ground to the highest point on the fender openings and it is about an 1 1/2 lower on the passenger side. He installed new 3/4 ton springs under it and it is still low on the passenger side. We haven't gotten under it and done any measurements yet. Any ideas on what this could be? The bed and the cab are both that way. Thanks.
