Hi,
I've read many many threads and I believe my problem to be the transfer case....none of the threads I read have my symptoms though. This all occurred in the last 10 miles
2002 ford explorer, 4x4, eddie bauer.
Here is goes......
The truck jerks/bucks while at a complete stop with the brake depressed. It's a thump, thump, thump
The thump gets better while driving and no brake being used
The thump is present in 4A, 4H or 4L
Unplugged the transfer case electrical and removed all 3 fuses.....same thumping, forward or reverse, 4h or 4l
All four wheels off the ground....thump, thump thump while brake depressed, let off the brake and the noise goes away.
I don't understand this - all wheels off the ground, brake depressed, the drive shaft is turning. I'm not familiar with this rear differential but I noticed is also has an electrical connection. It's a limited slip differential However, with vehicle off the wheels will turn independently - at other times it will engage the opposite wheel in counter-rotation which is what i expect.
Finally - transmission in park - the truck will roll sometimes but not all - leading me back to the transfer case.
Please help....
