Hello, I’m looking for a little help with my 2011 F150. I had the rear dif and gear box oil changed at a dealership and a short time later, I started noticing a slight shutter when starting off from a full stop, but only with the front wheels turned. It sort of felt like the four wheel drive was still engaged. So I though the front hubs weren’t unlocking, but I checked them and with the engine running, the front drive shaft is free wheeling. Any ideas?

If you have the limited slip rear, you are most likely feeling the clutches chatter. The dealer may not have put enough limited slip additive in when they changed your gear oil.

Saleen. Thanks very much, that makes sense as it started right after i had the fuild changed. I’ll go back to the dealership.
