hey ive go the same problem at the moment on my 33. pretty much squeels on startup then goes away, but at night time pretty bad.
i did all the spray lubricant and tighten belts but still same, turns out that at night cos heater and lights on squeels heaps but at day with no lights on its fine. so to test starts squeeling at night so turn everything off except lights and is fine bit weird but yeah.
so looks like battery is shagged so gonna recharge it. it nothing changes with the squeeling looks like replacing alt!!
ne one else found this lol
