Hello. Yesterday I replaced the front left hub assembly on my 2003 Explorer due to a bad bearing. I thought maybe the bad bearing was also the cause of the clunking and binding coming from the front end. Wrong. After replacing the hub assembly it's still doing it. It appears to be fine when driving straight. It only does the clunking and binding thing when making a slow turn. In drive and reverse. Also, the 4X4 High light will flash off and on maybe 8 times then go off. I'm not sure what to check first. The boot on the CV joint looked good, no cracks, but is it possible the joint is still bad? How can I check it? Or am I looking at something more serious? This is a V-8 with Auto. 4X4 with 91K miles. Any input would be greatly appreciated. About 3 weeks ago I changed the fluid in the rear differential. I used Royal Purple and the Motorcraft friction modifier. I have a 45 axle code.
