those rear axles usually hold up fairly well in the Explorers so I doubt it is a broken gear.
Does it do it turning both directions left and right what speed and throttle or no throttle?
Well so far have only driven it on a 5 minute test drive which is where I encountered the ratcheting effect the most due to the cornering in and out of driveway
And then a slow and easy ride 45 minute ride up m-24 ....white knuckle affraid something was going to break (rear axle ) or fall off ( maybe front wheel unit bearing ) ...so very easy driveing ...since this vehicle has sat for about 1 year before PO acquired it and traded it off
noise is definately when you put a load on it..while cornering ..1/4 throttle or more to get the tire to spin ...then noise starts and chatter feel happens
while driving straight it almost sounds like a bad front unit bearing buzz....which i have yet to verify or check into yet at this point
I simply am not used to this gen explorer and donot have any experiance with the axle that comes in it
I have had a 92 8.8 and it dint even come close to making any noises at all
I will drive this again on the road tomorrow once I get my Plate & insurance on it
