Has anybody experianced this type of problem? I have a 97 Expy.w/5.4 ltr 4x4 auto trans. After driving for about 10-15 miles and after coming to a complete stop,when i accelerate and turn left or right the suv gets a weird shudder that goes away. I didn't notice it on a stright out pull. People told me it could be the fluid in the rear needing a anti-slip additive. If anybody heard of this problem let me know. Thanks
