After waiting for a track bar bushing to arrive from RK since I thought that was the issue, it finally arrived and I noticed thread grooves starting to get cut into the original metal bushing sleeve. I replaced both track bar ends with 9-16" grade 8 hardware; this was all on Monday. Ill also add I only unbolted the track bar and rebolted it; I didn't mess with any of the settings with it (jam nuts etc.). Tuesday I drove it to work fine. Today (Wednesday) I was on the highway and I heard a chime and looked at the dash; the abs, brake, and tc light came on and the mph gauge dropped down then shot right back up to my speed. The tc light remained on and the other two went away. About 5 minutes later there was another chime and the same abs, brake, and tc light came on. During this one the mph gauge also dropped down then back up right away (the background of the instrument cluster was flickering also which Im assuming is from all the lights being on at one). I finished driving it to work and the tc light is still on. The steering wheel isn't off centered and all I did was replace the original 14mm hardware with 9/16" which seems to have fixed the wobble but now this happened today. This happened in the past before but with only the tc light, the steering wheel wasn't centered at that time and since I have gotten a front end alignment. Any ideas what might be the problem?
