Question about Cars & Trucks
I have a 1998 ford explored and when ever Im going up a hill at about 55-65 mph there is a pinging noise?
Too low octane fuel usage..overdrive not shifting out so engine is at lower rpm for the demand..

ISSUE: A "knocking" noise at start up for up to 2 minutes from the left hand front chain cassette area may occur on some vehicles. After engine shutdown, the tensioner oil supply gallery empties. The noise may be due to air entering the left hand tensioner when the engine is restarted.
ACTION: Replace the left hand camshaft tensioner with a revised Tensioner Kit. Refer to the Instruction Sheet within the Tensioner Kit for service procedure details.
WARNING: THE XU2Z-6K254-AA TENSIONER KIT IS FOR INSTALLATION ON THE LEFT SIDE OF THE ENGINE ONLY. INSTALLATION OF THIS KIT ON THE RIGHT SIDE OF THE ENGINE MAY RESULT IN ENGINE FAILURE. IF A TENSIONER IS NEEDED FOR THE RIGHT SIDE OF THE ENGINE, USE KIT XU3Z-6K254-BA.

what year is your explorer, if it is a newer one say within the last 10 years it could be from either the rear end or it could be from a hub bearing in the front end. these have problems with hub bearings going out.

change the fluid and filter in the transmission ASAP and that should take care of your problem. if you drive it too long like that you may not be able to save it.

The clunking noise could be coming from three different areas. Either the front or rear differentials could make that noise along with the transfer case. I would initially be looking at the transfer case as the culprit since you mentioned the 4wd light coming and going. My thinking is that the 4wd engagement solenoid is malfunctioning and trying to bring in the 4wd, then releasing it. The only good way to check the function and noise for this is to put the car on a lift.
