This is on a 2004 FX4 (has a 2'' leveling kit):
Just wondering, I think I will need to replace one...noticed today doing sharp jerks from left to right, I could feel a knock and hear a clunk in the front end. (Weird thing, when in 4x4, its not as bad). I figure its constantly under constraint so wont move as much as when in 2x4.

Very cold today; -26C first time this season, maybe had something to do with it also..

So I'm just looking for a ball park figure for prices...or Hrs of labour.

Later guys!!
