I’ve got a 95 L400 with a 4M40 in it. There was a terrible noise coming from the fan/belts/pulleys the other day. I couldn’t tell what was causing it just by looking and it seemed to go away after driving it home. I’ve taken off the belts and the fan. The fan looks like it was rubbing on something but I’m not sure if this was the main cause of the noise. The idler pulley for the AC is very loose/wobbly, but that might be due to having no tension on it with the belt off. I’m wondering if the crankshaft pulley might need to be replaced. If this went bad would it make noise? Could it cause the fan to rub against something? Is it pretty obvious if this pulley is bad? Not really looking forward to removing this, but everything else I’ve taken off already hasn’t been fun. I would have taken if off already, but my sockets seem to go from 19mm to 24mm so I need to find a 22mm.
Thanks,
