The shim between the inner bearing and the pinion is critical and if it's lost you need special tools to set the pinion depth. replace the bearings and seal with an new crush sleeve thighten the pinion nut until the sleeve crushes and you can't move the pinion up and down. Then very slowly tighten the pinion nut checking the rotational torque. You will need an inch pound torque wrench, when the preload is correct it should take between 20-25 inch pounds of torque to rotate the pinion. If you get it too tight you need to replace the crush sleeve and start over. Proper bearing preload and gear mesh are critical.
If this helps the sailsbury axle of a cortina details are crownwheel and pinion backlash 0.004-0.008" pinion bearing preload 0.001-0.003" collapsible spacer length 0.453-0.461".
A bearing backlash is what happens when the bearing loses motion or clearance. This tends to be caused by gaps that cause a period of non-motion.
Front Rear End? Does that make sense? Front differential? maybe? Low fluid, wheel bearing, choppy worn tires?

you have a bad tire or a bad wheel bearing i had this in my 2004 explorer twice, a tire,then a bearing the bearing makes more noise when turning right to left when traveling
the cost for driverside wheel bearing on my 2002 ford,explorer,xls-4door,4x4 was $130.00 at the advanced auto store locally. if your explorer is a sport explorer i have a front wheeling bearing that i will sell you for 75.00 still in the box. i missordered. other wise, specifie the model. good luck!
Depending on the vehicle, a diff bearing kit is a kit you can purchase that contains all the parts to freshen up a differential. This usually includes the pinion bearings and races, pinion bearing shims, pinion seal, pinion crush sleeve, pinion lock nut, carrier bearings and races, carrier bearing shims and a new gasket.
The bearing are sealed and can not be repacked.
Which differential bearings? Pinion bearing? Carrier bearings? End axle bearings?

I would suspect a defective universal joint on the driveshaft. Can also be a bad wheel bearing or axle bearing. And lastly, a problem with the rear differential. Check the gear lube level in the differential first.
