Let me take a WAG at this . I am guessing that you have a truck with A/C and a single gas tank on the side that sits lower . I have had several of these and every single tank A/C truck I have had has leaned 1 to 1 1/2 inches to the right (passenger side ). My non air single tank 78 doesnt do this . My 77 long bed , my 35,000 original mile short bed I sold and several others that have come and gone , have all leaned . I also replaced the coils in my current 77 but it still leans . I am going to swap the leafs and coils from side to side . I believe that 30 plus years of supporting the added weight of the A/C and gas tank with fuel and doing it 24/7 weakens the springs . My problem is that I couldnt find a good source for new springs that was affordable . I have a set of new matched lowering springs that I thought about installing to see if the rear levels out . I have also thought about adding just one extra leaf to the passenger side to support the extra weight . If you jack the rear up to sit level with the other side , believe it or not the front will attempt to level out since the low side gets a little help and the front high side gets weight shifted to it and in turn lowers a bit .
