And like the shop told you to much idlilng.

When you idle especially at low rpms not enough cylinder temp is created and this allows oil to sneak past the rings eventally coming to rest in the turbo and then leaking out

Front end shaking----- Get a good three axle alignment. The rear ends have to be square to the frame and parrallel to each other and the front axle has to be parallel to the rears. And the rears have to be in line with each other.

I had the 45 to 50 shake and wobble. I knew when it would start and when it would stop. Some road types it would not do it. More or less crown, flat etc.

There was a alignment guy on Dave Nemo a couple years ago and he described this wooble problem to a "T" . He said that the rear ends are the problem. So I started measuring and using strings and got the rears allot closer and the wooble went away. Then I got a three axle alignment and the alingment shop got everthing to within a 1000ths of a degree. Truck is perfect now. One rear had to be moved 7/32"

Also take the top off your power steering pump tank and with your truck at a idle look inside if it is foamy looking you have air getting in some how and that might cause a wooble in your steering.

Hope this helps
