Hey guys and gals. I have a 2003 Tahoe with 180,000 miles. Recently I had a wheel speed sensor on my front left go out. I havent had to do a wheel speed sensor so I am not even sure how to do it yet. I got a quote at my trusted mechanics shop of $250 or so. I can get it from rockauto for 30 not including shipping. Which do you guys think is more worth it? Pay to get it done, or Do it myself?
