Okay, this may seem like a Captain Obvious question to a lot of mechanical types, but at highway speeds, the Serious Satellite shimmys. I'm getting new tires mounted all the way around, but I'm kinda wondering if I don't have a lower arm bushing problem.

Any suggestions?

And please, it may seem obvious to you, with my memory, it ain't so obvious these days. So take it easy on an aging old Mopar Ass. ..

possibly motor mount??? that's what was wrong with mine...passenger rubber split in half

Same thing happen to me in my Satellite. Like you pointed out, it could be many things, but it was my tires. I would get to about 65/70 mph, and the front end felt like it was about to blow apart. The side wall on one of my tires was bad. I put on a new set all around, and I took it to over 100 MPH, smooth as silk .

CHECK ALIGNMENT AND WHEEL BALANCE.

IF IT CONTINUES PAST THAT.

CHECK BEARINGS AND SUSPENSION COMPONENTS.
