I have a Ford Explorer Sport Trac 2002 and need to know what the knocking sound is coming from the front passenger wheel area! It started off with the truck making a squeaking noise when i was driving over uneven roads or driving up the parking garage basically whenever the front two wheels were on different levels. The squeaking was on both sides of the truck front wheel areas. I figured the bolts needed oiling (Sorry I'm blonde!) or that the suspension needed new springs or something like that but now I have a knocking sound coming from one side, the squeaking is not so bad now I have a knock!! It doesn't really make a knocking sound when I turn the wheel left or right, it will knock when I'm just driving straight and I don't think it is as bad when I'm doing 45-50mph but don't rule that out! It has gone from me noticing the knocking a week ago to being loud and a little worrying! I would say it has worsened 60-70% in a week so I probably shouldn't be driving it until I get it looked at!? I would love to have a rough idea before I go to the shop, being a women I feel that some mechanics, not all, but some will tell women anything knowing we probably have no clue if they are right or wrong! I don't want to show up green and end up handed over all my green for a loose bolt! Lol So anybody have any suggestions?
Do you feel it in the steering wheel? if so it could be the intermediate steering shaft. If not it could be a sway bar link or bushing.

This is the problem with suspensions problem of the car or major problem with the engine in the car get it check by the dealer as this may factory defective part install as this car is still under warranty.........................................................

Have a mechanic check lower control arm bushing at the rear of the control arm.It is a horizontal bushing retained by a vertical bolt clamping it to frame.The tire will move more forward and back more than it should during braking. canuck mechanic.

This is a big sign that you might have a spun rod bearing if it's coming form your oil pan. Use a screwdriver and put the flat tip end on the oil pan and the plastic end near your ear like a stethascope and if you hear a knocking it's probaly a spun rod bearing or a bent or warped wrist pin on the bottom of your piston. So some good advice is to not run it anymore until you get it a mechanic to fix it. If you want to do it yourself you have a job ahead of you but refer to an Haynes Auto Repair Manual and you will have fun doing a job by yourself. I hoped this help!

I had a noise that I also heard off and on... I thought that I had possible leaf bushings getting bad. Found out all it was, was a couple of loose fender bolts that had come loose from rough roads.
