I have an 06 expedition that is a former police vehicle. I'm getting a vibration from the rear end when turning from a stop. Backing out of the driveway and then turning aroun. That type of thing. I believe it has an LSD. I've already replaced the differential oil and put in the friction modifier, but it didn't make much difference to this particular vibration. Any ideas what else might be the issue?
Thanks.
Thanks.
