Ok so i own a 97 wrangler sport, ive found it has a shimmy, but only some times. Some days, ill drive it and it likes to shake a little bit (small shimmy in the wheel) at around 55 and up, but if i slow down or stop it will sometimes go away and sometimes it just goes away on its own, and it isn't always the same intensity of shake... And it has always shook pretty good at higher speeds like 70-80. The fact that it goes away sometimes leaves me baffled. Any ideas? Oh and I've checked the track bar and steering up front (where the shimmy seems to come from).
