Hi Everyone! I've got my hands on a 1999 Explorer and I've been working on it for a few months now. I've found an issue that I just can't pin point. When the car is in 4x4 Low and you turn left or right towards the locks, it has a terrible clunking and knocking noise coming from the front end...

2016 Explorer Limited 2WD, ~38,000 miles all city and highway I have a "thunking" noise that could probably also be described as a popping noise while turning at very low speed. Essentially when turning out of my driveway. It doesn't happen every time - maybe 1 out of 4 or 5 times. I don't...

I have a neglected '94 Explorer with a 4.0 OHV engine, my brother and I are rebuilding. My issue appeared after fixing warped heads. A loud, almost a tin can clacking sound started somewhere on the drivers side of the engine. We've also changed spark plugs, wires and the ignition coil, but...

So I pulled my 4.0 replaced the timing chains, oil pump, water pump & the passenger side head. I had to replace the head because it developed a crack and started sucking coolant. The truck has 215k miles on it so I decided to pull the engine and replace the head & timing chains.. It's a good...

I'm having a very faint rattle/chattering noise suspected to be around the left side of the engine more towards the back, but it could possible be in the front. Definitely more prominent on the left (passenger) side. It doesn't sound severe enough to be a timing chain, and it doesn't sound...

Hey, so problem after problem that comes up on my truck, I try to address each one accordingly.. Recently I've been having an issue where the car is surging very frequently and rhythmically. At a complete stop in gear, the car surges "vroom, vroom, vroom, vroom" and the RPMs quickly...

Hi there, current issue with the truck is... There is a knocking sound, seemingly coming from the bell housing. Background is: I traded a van for the ST, ST ran like crap, changed plugs and wires. Plug on driver side rearmost cyl. broke, shoulders and all. Shop removed threads and...

Hello, My 1992 Eddie Bauer Explorer's engine purrs along perfectly when the vehicle is in neutral or park. When I put it in gear (and the engine is warm) there is a knocking sound from underneath whenever I have my foot on the brake. When I start driving, it goes away. It doesn't happen...

Hey, I've got a recently acquired 93 explorer xlt and at idle there is a knock that is on for a few seconds then goes completely away for a few seconds, and then back on again. The guy that owned it before said it was a sticky valve, but i dont understand how it could knock one second and be...

I've never posted before, but have found a ton of helpful info from you guys!! Anyway, here goes... I have a 1997 ex with the 5.0 and awd. The problem is a serious clunking / knocking sound from under the front end. First thing I thought was the driver's side cv joints. The noise would start...

I drive a 1991 2-Door Manual Explorer. I was driving around the other day with a buddy and we rolled down the windows. This was when I started to hear a clicking noise as I accelerate. It usually happens in first or 2nd gear, but really as long as I am above 2500 RPM's I can hear it. It is not...

I have a 91 xlt 4.0l v6...when I put my foot to the floor it makes a knocking/pinging noise...I was wondering what I can do to fix this? I am filling it with regular from chevron so its good gas...can my intake have any input on this? lack of octane? Thanks!:us:

Just recently has my car started clicking and I am pretty sure I have narrowed that down to be the a problem or a leak with the Cat. However, I was driving home today and my engine started "knocking". The knocking got louder as I would excellerate and I could kind of feel it in the gas pedal...
