First post folks - what a great forum you have here, been lurking for a while and learning a few things about the Exploder, sorry, Explorer !!!
Anyway, would be good to get some help and advice on a problem I have please.
'98 UK spec 4.0 V6 auto - it's a truck I look after for a disabled friend of mine.
Has a rumble from the front end, which I originally thought might be a wheel bearing, but having checked them both - they're fine. The rumble has only recently started. We don't remember it starting quietly and getting worse, it just seemed to suddenly be there. Starts at a round 20 -25 mph, gets a bit worse up to about 40 and then just levels out in terms of type of noise and volume.
Rumble is there in 4wd auto and 4wd high. Not sure about it in 4wd low as the noise from the engine drowns it out, if it is there, when you get up to enogh speed that you would be able to hear the rumble.
I've just changed the diff oil and that didn't make a difference. Oil was slightly emulsified from a few dunkings while off road. This may have resulted in some damage to the diff gears, but was hoping that fresh oil would help. Eventhough it's emulsified, it still seemed reasonable - no worse than another 4x4 of mine (Mits L200) has often suffered without causing any damage.
I'm still trying to get my head round how the 4wd auto works - is it possible the control system is trying to engage 4wd when it shouldn't and is only partly engaging 4wd. The L200 has a diff actuator that, if the vacuum system is acting up, will try to engage the diff, even though the 4wd shift is still in 2wd, and then gives a rumble fromt he front diff, so I'm wondering i the Explorer is the same or similar.
Transfer box has good condition oil - was changed a couple years ago, but the truck is used so little, I'll bet it's only done about 10,000 miles at the most since.
Your thoughts and advice will be greatly appreciated.
