I never notice it on turns. Mine shudders when the engine is fairly cold and under a very small drag. For instance I am going up a small grade with just enough accelerator to maintain speed. If I accelerate more it stops. I have frankly not been able to figure out what is causing it. I ran across this thread and wondered if that may be my issue. Thanks for any advice.

 

Doesn't sound like the limited slip causing the problem, but at the miles you're at may as well change the fluid.
Have you changed your plugs? If not they were due 30,000 miles ago

 

I have not changed the plugs. The prospect of broken plugs that I have read about has prevented me from doing that. Guess I had better get it in

 

Have fun haha. Ya those should have been done at 60,000. I was lucky enough to have mine done before I bought my new truck.

Also motorcraft only. Unless you wanna try the champion one piece.

 

I think I will let the dealer do this job.

 

Good idea. Make sure to run some Tecron in the gas for a few tanks before bringing it there to help bring down the chance of snapping the plugs.
