Message: <blockquote data-quote="Johnny Raptor" data-source="post: 5884" data-attributes="member: 2983">Yeah, I just had to mention the Lane Keeper because it lightly vibrates the steering wheel.  I leave it turned off on our Broncos; it’s annoying to me.A couple of other questions:Does the vibration change with speed or is it constant?  Since the dealer worked on the IWE, is it possible it’s in 4WD all the time?  It’d definitely feel weird on pavement if it is.  I know on my Gen 1 Raptor the IWE’s are vacuum activated, so if they lose vacuum they engage 4WD.  I don’t know if this is true on my Bronco Raptor, though.   Somebody else may be able to weigh in on that.Do you know if they replaced a damaged CV Boot or the whole CV half-shaft?  If you had a torn boot and lost the lubricant or if dirt/water got into the CV joint, it could’ve trashed it.  A bad CV joint could also cause a vibration.Not sure if any of that helps you out, but those are the things that come to mind based on the symptoms you mentioned.  I’m also assuming you aren’t running high pressure in your tires (like 45-50 psi) and that the alignment is in-spec and no other mods have been made to your truck.</blockquote>
