Got a question or two for you all. On cold morning upon start-up my 4runner makes a kind of thud sound which vary in loudness depending on how cold it is.

The second question is on cold mornings (again) when I start my vehicle up there's a bad vibration and when I reverse out of my parking space the vibration increases till I put it drive and start moving foward. It will also do this off on and while at idling.

Any idea what would cause these issues? The past 2 4runners I've had didn't have these issues.

Vehicle 2002 Toyota 4runner with 173,xxx miles

 

Have you greased the driveline zerks?
