Fsti drone
I don't know if any one has thoughts on this one , it's a fsti its on 140 k miles , on very light throttle between 50 mph to 70 mph ish , I get a resonating drone noise it's difficult to tell if it's transfer or rear diff I don't know if it is transfer or diff I'm assuming it is , as soon as I accelerate normally it goes away , it's only there on light throttle , it does not appear to be wheel bearings , it sounds like resonating rather than worn gears , I suppose it could be early stages of a bearing failing , the diff and box appear fine noise wise when it's been driven under acceleration , I've checked out diff hanger bushes they seem OK , the rear diff bushes seem OK , any thoughts please ?
