[QUOTE="DreamcastERA, post: 1763322, member: 34087"] I hope I'm posting this in the right place! I, of course, have developed an IWE problem. I've been hearing a rattling/grinding noise on and off at highway speeds for maybe the last 4k miles. I originally thought it was a loose bolt, and basically convinced myself o that when I found a very loose skid plate bolt. The sound was intermittent enough that I could go very long stretches without hearing it at all. When it did show up I'd go looking for something loose under the truck (I'd find a loose clamp or bolt every once in a while to throw me off) - I even had a shop try to replicate it but they could not. Recently I noticed that my driver side CV turned when in 2WD but my passenger side did not. I noticed this while investigating a leak from the diff where the driver side CV slides into the carrier. I determined that I have adequate vacuum and that if remove the vacuum lines, the passenger side CV will also start turning. This indicates to me that my driver side hub has been engaged (or partially engaged) for maybe 4k miles on its own in highway conditions. Which is likely related to my diff leak, which is pretty scary tbh - the shop that replaced my driver side axle seal commented that the CV seemed to have too much play in the diff; lo and behold, the new axle seal did not stop the leak. I'm taking it back to the shop that replaced the axle seal and they're gonna check to see if there's any obvious damage to the diff or wheel bearing. Im also gonna have them replace the IWE on the drivers side so I don't have to spin my potentially damaged diff all the way home. I'll update when I learn more, but I figured I'd post this here just incase someone else comes across a similar problem - or maybe if some of y'all have had a similar issue or any advice! [/QUOTE]
