I understand what you are writing.
It seems to me the nose of the Expedition is still a bit high as is the front of the trailer.
This is after the latest change the dealer made: full ball cant and IF I have the bars really tight--that is narrower to the frame--not parallel, it is better than it was before I complained.
Before (done by another dealer) the Expedition really went skyward in front but the trailer was level and the ball was not at maximum cant....think it was on 4 on those concentric (sp) washers.
If I were to work on this myself, I will have to buy bigger wrenches
Nothing I have goes large enough for the taps/nuts on the bolts.
I could take it to another shop, I guess...... I would like to know what really is wrong.
If I lower the ball (have bar with lotsa holes/choices) one hole leaving the ball at full cant, will I achieve anything.
To me this is like a rubrics cube. The Expedition must have very weak rear springs....I don't have the air-bag system.
I understand the principle but what do I do first.
