I went up north last week to pick up my wife and the roads were icy on and off, so... I engaged and dissingaged 4wd Hi - while driving @ 100kph. there were no noises or grinding when engaging or dissengaging at that time and the 4wd was working.
Today I tried to engage it while driving at about 30 - 50kph and it just made the worst grinding noises I ever heard. I had to stop for it to engage. Did I wreck something when engaging at highway speed? It never did this before. I know I need to stop for 4wd low but wasn't aware of 4hi. I had posted in the summer about a vibration at higher speeds when the hubs were locked and found the cv boot on the pass side was split and it only vibrated with the pass side hub locked (problem found?) could the vibration have caused something? Anyway... do you 4wd gurus have any ideas? Of course you do, that's why I post here <img src="/forums/images/graemlins/nana.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />
