I own a 1998 Explorer with about 170,000 miles on it. My problems began with a high speed whine. The noise occurred when above 40 mph and your foot was removed from the accelerator.
Stegall's Transmission Shop in Greenville, SC rebuilt the transfer case. They did a great job and answered tons of questions about it and my other 4WD. The problem was a bad shift motor which damaged the range hub.
Well, after the transfer case was rebuilt, the Explorer began to make a popping type of noise when climbing a hill (under load) - 30+ mph. The noise has not occurred except for climbing a hill. The majority of the time, the noise occurs when you lift off the gas then get back into the gas hard … like climbing a hill with a curve (in the throttle, out for a sharp curve, and back into the throttle and POP - as if something is snapping back into place). Sometimes, the noise occurs when you are in the throttle the entire time on a hill. I have never heard the noise while driving downhill or on flat terrain.
The Transmission Shop (Stegall's) completely rebuilt the transfer case (replaced all of the guts at no charge to me), but the noise still occurs. Then they replaced the transfer case with another rebuilt transfer case to rule it out the transfer case as the problem (again at no charge to me).
The rear diff was checked satisfactory with no issues, the front drive shaft was pulled and the mechanic thought that the front diff was the problem…well, $450 later, the popping noise is still occurring…
The explorer seems to steer just fine and is not a suspension issue - I think. However, I did put new shocks on it this past summer (after the transfer case rebuild)...but I don't remember if the shocks were installed before or after the popping noise began...
Any thoughts? Thinking about pulling front driveshaft again and driving it myself to see if noise still occurs (I know the vehicle better than the shop and know how to make it "do" the noise...).
