two issues- '03 Wrangler rubicon, factory MTRs 1- at low speed (less than 10 mph) the vehicle exhibits a side-to-side rocking motion sort of like one tire has a large flat spot. I've rotated and checked them, nothing obvious.
2- around 50 mph, front end shakes violently, settles down a lot over 55, and is almost unnoticeable at 45mph or less. this started happening about the time I noticed the steering wheel returns to slightly left of center, and must be in this position for the vehicle to stay straight. Alignment seems ok best as I can check, and haven't found anything loose in the steering system so far. Anything else to check?- charles
