I'm at my wits end trying to identify the source of a rear end persistent squeaking - admittedly after about 7000km of offroad travel with canopy on the back and towing a camper trailer.
Have ARB (OME) suspension kit fitted, plus air bags, but can't see anything obvious that is remiss with this.
Sounds like metal on metal, and occurs when driving now on bitumen (but maybe I was just not hearing it on the gravel).
Doesn't appear when first starting off, but after getting underway for 50km or so it comes back and is there for every minor undulation in the road surface.
But of course I can't hear a thing when walking alongside the vehicle at slow pace with the Mrs driving, and can't demonstrate the problem to a mechanic.
Any ideas ???
