I bought my bronco about a month ago and thought I would have no issues for awhile. Previous owner took good care of it and did a lot of work on it himself over the years.
I am not overly skilled mechanically, but one thing I felt I could handle was changing all the dash and cluster lights bulbs to LED. Went fine and looks great. The day after my ABS light came on, and at first I thought maybe it was tied to LED's as those seem to cause other issues. For instance, I replaced my headlight bulbs and turn signal bulbs with LED. Headlights fine, blinkers fine when I did front. Once I put them in the rear blinkers stopped working, so I removed them. Doing a lot of google research I couldnt find anything that showed a correlation between the 2(LED and ABS light)
Finally took to a mechanic who has the correct OBD1 reader and was told I needed to replace the sensor on the rear differential. Once replaced, it went off, but came back on shortly after so I took it back.
The mechanic stated he would try to further diagnose. He thought there might be some metal flakes/shavings in the differential and that the sensor had a magnetic end, that they could be sticking too and causing issues. So he pulled it, and cleaned it to put back. HE told me if that cleared the light, then he would drain/refill the differential. He said when it was in the air, with engine running and in gear (tires moving at about 20mph) that the light went off. But when he hit the brake, it came on. He was behind at the shop and had my bronco for 4 days so he called me to come get it. He didnt charge me, but said he was at a loss as to what it could be. (never did drain/refill differential) When I drove it home, the light was on, but at one point it went off for a few seconds, then came back. Anyone else ever have a situation like this and can help lead me in the correct path? I do have an appointment next week at a Ford Dealership service spot, but not feeling overly enthusiastic.
