2011 navigator 5.4ltr
I replaced my steering rack because it started leaking but even before that the cooler line came off..
Anyways u ended up replacing rack because the seal leaked then I replaced steering shaft which made a very little difference almost nothing so I asked the mechanic to take it out because I'm not paying for his experiments
Then I replaced upper ball joints(control arms) both sides.
They were not so bad but not so great either
The lower ball joints were replaced four months ago but economy class because the mechanic was an idiot and he charged me $800 for upper and lower basically he robbed me.
Does anyone have the same issue
I got winter tires I don't think that is the reason.
