Hi people,my 87 tdt just got some work done,i put new spheres in the back to help out give me a smoother ride,then i bled the system and i see no leaks,but my rear will sag for a week after i put a heavy load,i cant tell it it reloads by uitself or a long road trip will spring it,i was wandering if anyone knew what could be causing this,before i changed the spheres i had a bumpy ride but it would never sag after loading it up,but now when i go to costco and buy a lot of heavy stuff such as water cases etc it will sag for days.

Just guessing, sounds like a leveling valve. DId you bleed the system? Must be a bleeding proceedure (although the leveling valve should be self-bleeding, the dampers and spheres I don't know).

With appropriate safety precautions, you should be able to disconnect the level control rod and operate it by hand to see if the valve is working correctly. The rod is adjustable I believe.
