2TrakMind Posted December 9, 2009 Share Posted December 9, 2009 I replaced my auto locking hubs with manual hubs a year ago, when the autos went bad. 4WD worked fine last winter. I haven't had it in 4wd since the snow thawed. The other day, I locked my hubs (without engaging 4wd)and began driving. Immediately, there was a metallic sounding clunking that increased in speed as I increased my speed. I tried to engage 4wd, but it doesn't seem to engage. If I go in reverse, there is no clunk, and 4wd seems to be locking. Any ideas of what this may be? Thanks! Link to comment Share on other sites More sharing options...
Precise1 Posted December 9, 2009 Share Posted December 9, 2009 Disassemble the hubs to inspect and make sure they are engaging properly. You may have crud in there from last year... Clean and lube everything and reassemble/test. B Link to comment Share on other sites More sharing options...
MY1PATH Posted December 9, 2009 Share Posted December 9, 2009 have you lifted the vehicle at all but cranking the t-bars? IF its too hight the cv's will bind making a similar noise. Link to comment Share on other sites More sharing options...
GrimGreg Posted December 9, 2009 Share Posted December 9, 2009 Yeah, I was gonna ask if any of the rubber CV boots were tore open, if so they are probably dried out and bound up. Link to comment Share on other sites More sharing options...
2TrakMind Posted December 10, 2009 Author Share Posted December 10, 2009 I don't have a lift on it, but do have one torn CV boot. Maybe that's the cause. Thanks for the input! Link to comment Share on other sites More sharing options...
