low speed rumble
Hello to all:
I'm new at this so please bare with me. I have a 1999 EB Expedition (94k miles) with A4WD, 4WHI, and 4WLO options. I get a low speed rumble which seems to be originating from the front end. The rumble occurs from a stop to approx. 20 mph and 20 mph to a stop. I replaced the front diff. with Mobil 75W/90 (owners manual recommended wt.) synth. The rumble stopped for about several weeks only to return. The front CV joints do not make any noise like clunking or clicking typical of CV joints while hard turning. I recently bought this used so I don't no the maintenance history, although I'm sure they did not change the diff. fluids as recommended. Any thoughts would be greatly appreciated!
