Pulls to the right on acceleration

[jetjock46]

Hi,
I have a 2000 Expedition that I have had since new. It is and Eddie Bauer with the 5.4 and 4x4. My question is, when I accelerate it pulls to the right and when I decelerate, it goes to the left. It really is the worst when I am towing a trailer. I replaced the idler arm and that helped, but it still does the same thing. I was wondering if it has something to do with the auto 4 wheel drive system?
Any Ideas?
Thanks for your time.

This is gonna sound really dumb....But mine did something similar and the stabilizer pin on the passenger side was shot.

I dont kow the extent of your issue but mine was a subtle to slightly annoying tug.

Definitly noticable. Cant hurt to look.



Hell, it may have nothing to do with it.

maybe the shocks?

I'm not sure what stabilizer pin your talking about, but I will check to see if there is something that seems loose. I have replaced that shocks about six months ago with no change.
Keep those cards and letters coming!!!
