Outer Limits 4x4 Board

hi
i have developed a rattle coming from the front of my 97 diesel pajero when i hit bumps, mostly on dirt roads. A couple of months ago i got one of those peders safety check things done and they said the front idler bar was loose.. still havent done anything about it.. could it be this getting worse..
thanks

hmmm????? what do u think? if it was loose befor and u didnt change it do u think it would get better or worse? think hard and youll find ur answer.
