So, the other day, my xj started making a little hop, or clunk, every now and then in the front end while it was in 4x4. I took it out of 4x4 and drove on the icy roads in 2wd, just in case. I figure it's a hub thats going/is bad, am i right in my assumption? I mean, i already bought a new one, so i hope i'm right.... Btw, it's an 88 laredo, 4 inch lift, 33's, 4x4.
