Vibration When Turning

My 05 PSD has developed a strange vibration. It's very specific about when it's present. From a Stop sign or red light, if I turn right or make a sharp left and accelerate normally, there's a vibration or shuddering feeling for a few seconds. If I drive off straight or sweep the turn out, it doesn't do it. If I turn and go slowly till I complete the turn, it doesn't do it. As near as I can tell, it's coming from the rear. Any ideas?

I had that problem on my truck. Make sure it is not coming from the front. Ball joints were shot. I replaced them with BJ's that had grease fittings. World of difference.

Good luck.

It's not the ball joints. They're tight. I wondered about the limited diff so I pulled the plug. When I stuck my finger in to feel for oil, there was a hard ring of sludge around the hole. It felt a little low so I bought some oil. Next day, I pulled the plug and it had about 1/4" of almost solid deposit on it. I assume it's magnetic? I guess a trip to the Ford House is my next step.

Did you check your power steering? Might be something going on there that's keeping it from acting right.

Front end or rear?

front = 4x4? hubs unlocked?
rear = time for a diff. service?
