about 12 years ago we had our mechanic install a 3 inch left on the 98 xj...which was kind of a mistake because he never works on lifted vehicles. i'm not sure what all parts were changed, but i have recently come to realize that the stock swaylinks were left on, so the sway actually lays flat. well the bushings are shot too which they need replaced for sure. I was more curious about the lack of any angle and the impact it has on the highway. could this cause the ever so slight wobble at 50 mph?

Thanks in advance

 

It would not cause a wobble, that could be any number of things, but the first place to check would be if your track bar bolt is tightened all the way. You want the sway bar angled about 10-15 degrees up to get maximum performance out of it, which could be achieved by getting longer sway bar links.
