    oil pressure gauge dropping out, again, 2002 XLT 4.6L 4WD

    Also, 5. When you have the oil pressure sensor off, this is also a good time to hook up an analog gauge and read the actual oil pressure instead of the idiot light version. A pressure tester kit is about $30. This is another job that is a pain because of the limited space but if you have...

    oil pressure gauge dropping out, again, 2002 XLT 4.6L 4WD

    Just a few suggestions. 1. If you have the v8 and have not already done so, you will want to look at doing the repair outlined here, Have a 4.6L? Here's a problem I bet you all have... The first thing to go with this issue is the connector wire for the oil pressure sensor. I don't think that...

    brake dust shield fasteners

    I didn't buy these because the stick figure picture at the Ford site looked like the rivets you posted and not like the OE push pins. My dust shields were so roached that I ended up getting a pair of used knuckles from ebay. They were about $50 each and had intact dust shields with only a...

    Help identifying this disconnected cable

    I don't see the engine type listed anywhere in your post. Is this a 4.0L v6 or 4.6L v8? LMHmedchem

    4.6 loud shreiking noise?

    Hopefully someone here has had the same issue and will at least be able to post what the problem is. You mentioned checking the belt system. Did you make very sure that the bearings in all 3 of your idler pulleys are good? Do they spin freely? I would expect that you would be able to tell that...

    4.6 loud shreiking noise?

    If there is a leak in your exhaust at the manifold that is causing a loud noise, I would think that there would be a jet of very hot exhaust at the leak. The exhaust would have to be very accelerated to cause a loud sound so I think that you would be able to detect it. If you had a smoke machine...

    Dorman 4.6l intake coolant leak

    I have not had to do this repair as of yet but I have been thinking that it might be possible to tap the inside of the port and use a threaded plug. I suppose you could also use a die and thread the outside for a cap. Does anyone thing that such a solution would be possible? LMHmedchem

    Front End Grinding/Scraping Noise

    Does the sound sound like it is coming from one side more than the other? I would do the easy stuff first. I would take off the wheels one at a time and spin the hub with the caliper and rotor still installed. First look for the rotor scraping against a rusted/bent/broken dust shield or...

    shifting after engine work

    I don't know if others agree, but what you describe sounds like the typical problem that arises with these transmissions. The transmission flares when trying to shift from first to second and when trying to shift into overdrive. Much of the time it won't go into overdrive at all. This is caused...

    Weird electrical glitch - charging system malfunction dash light flickers - bad alternator?

    You can test your alternator (mostly) if you have a DMM. With the engine off, use a screwdriver to pry loose the red cap on the alternator. There are several designs, mine is just a flexible silicone cover. Don't do this with the engine running. With the engine running, turn the DMM on to...

    ABS Code C1233 Missing Input Signal Left Front

    The ABS sensor helps to detect if the wheels are moving at the same speed. There is a tone ring inside the wheel hub and bearing assembly. This is just a ring with teeth in it like a gear but wider. The sensor is magnetic and reads the teeth of the tone ring passing by the magnetic end of the...

    Rear Diff replacement

    If you get a used one that has not been rebuilt I would try to replace as much as you reasonably can before having it reinstalled. I would at least replace the carrier bearings/races, the pinion seal/bearing/race/crush sleeve, and ring gear bolts. All of this can be had for $125 or less for a...

    ABS Help!

    Is your truck RWD/4WD/AWD? You mentioned that you already had the front hubs replaced. The hub and wheel bearing is a single assembly on these so you have already replaced the front wheel bearings where you think the sound is coming from. Do you know what was used for those parts? If you have...

    Need to find some fuel injectors for my 03 4.6L that are not made in China

    You an get Motorcraft from Carid or Jegs, Motorcraft CM5184 Fuel Injector ($69.67) Motorcraft Kit 6F1Z9F593B Fuel Injection ($73.99) I don't actually know if these are new or remanufactured. I get 2 Ford part numbers; Motorcraft CM5184 and Motorcraft 6F1Z9F593B. One is probably the...

    2002 Ford Explorer XLT 4.0 Rough Idle at Times...

    You posted that you cleaned the IAC and the throttle body, not the MAF. Maybe you forgot to add it to the list? Other than running a can of Seafoam through the upper engine you seem to have ticked all the boxes for cleaning. I am not sure that Seafoam would help a rough idle. If your spark...

    Did you clean the MAF? The airflow sensor should be cleaned along with the throttle body or when you change out the air filter. Make sure you use the correct cleaning fluid if you do this. LMHmedchem

    Passenger window wont go up

    It's possible that the window is disconnected from the regulator or that the regulator is disconnected from the door. There are allot of parts that can rust and break in these things. If you remove the panel, you should be able to manually push the window up and wire it in place. By doing that...

    2005 Ford Explorer Rear Passenger side

    Some of the best body panels are made by Mill Supply, https://www.millsupply.com/auto-body-rust-repair-panels/ford/explorer/2005/ I have never had to deal with their customer service before but it has a good reputation. I would contact them with pictures and ask about the parts you need...

    Timing Chain Tensioners

    Also, sludge in some locations of the oil system can impede the flow of oil into the tensioners. When you changed out the tensioners, did you check to make sure that the port in the back where the oil enters the tensioners was clear? A partial blockage may be worse at low RPM which fits what you...

    2002 4.6L XLT 4WD Power Steering Pressure Switch (where is this thing???)

    Well that is good to know, but why does is it there at RockAuto listed under steering parts for my engine? That I can even understand somewhat, but even worse, why does a Ford parts diagram with that part come up under my Engine? LMHmedchem

    2002 4.6L XLT 4WD Power Steering Pressure Switch (where is this thing???)

    I was looking though a power steering part list today while putting together a list of parts for a friend. I came across, power steering pressure switch, STANDARD MOTOR PRODUCTS PSS4 there were a few other models as well. I also found the part at a Ford site for my engine, Ford 3F1Z3K215A...

    Oil pan bolts

    I would think that someone here would have replaced those bolts since I would definitely paint the pan and replace the bolts if I had the pan off for any reason. I more or less replace every nut and bolt that comes off of the truck now as I also live in the land of salt and rust. Someone may...

    Oil pan bolts

    I do not know the size of the bolts but if you can remove one of them you can take it to a hardware store to determine what it is. My guess is that it is something like M8-1.25. Also, my rule for many years has been to make sure you can access and break loose every one of those rusty old bolts...

    Running Rough

    I sort of doubt that miss-fires were being caused by the spark plugs needing to be a quarter turn tighter. I would think that the plugs would have to by very loose indeed for that to cause an issue. Such an issue would not likely be intermittent either. All that said, I think it is a very good...

    2002 XLT 4.6L 4WD brake line stuff

    I wonder if anyone here has a diagram of how the hard brake lines run around the frame. In particular, the long line that runs along the drivers side to the back is a bit confusing. Most of the line runs along the outside of the frame under the runner board and that part will not be a problem...

    Front Rotor & Pads Recommendations

    Sorry for my confusion. The PowerStop coated rotors are "Geomet coated". I am familiar with the Geomet coating process (it's just a zinc aluminum variant) but I don't recall seeing that term on products other than PowerStop. I wonder if EBC and PowerStop are the only manufacturers to adopt this...

    Front Rotor & Pads Recommendations

    I have never seen any dust on my wheels. This is not a vehicle that I put allot of miles on so I guess that may be a factor. It also rains and snows allot here so that may affect dust buildup as well. Dust is at least somewhat correlated with stopping power. A higher friction coefficient means...

    Front Rotor & Pads Recommendations

    Yes, that's fine. There are quite a few brake setups that use semi-metallic up front and ceramic in the back. About 70% of your braking happens up front so it's common to use front pads with better stopping power. The Raybestos Element3 rear pad set is only $28 and it probably wouldn't add to...

    Disconnected ABS Module; False Engine Failsafe Mode?

    RockAuto lists that Cardone does a return and rebuild service for the ABS control module you need. The service goes about $250 +ship. Cardone is not my first choice for auto parts but you may have limited options. I don't know how long the service takes. This is another site that advertises...

    Front Rotor & Pads Recommendations

    The Brembro front rotors are currently $74 +ship each on RockAuto. That is more than twice as expensive as the Raybestos coated rotors. Is there some reason they are so expensive? Does Akebono make pads that are not ceramic? There are none listed at RockAuto at the moment. There ceramic pads are...

    Front Rotor & Pads Recommendations

    When I have used the Raybestos EHT brake pads I find that there is no sound whatsoever, at least none that I can hear from inside the truck. I think they are very smooth and quiet and work very well. As with all brake pads, they should be worn in (burnished) according to the manufacturers...

    Front Rotor & Pads Recommendations

    You might want to consider a hybrid setup. RAYBESTOS 833H680014E3 Element3 Front Kit ($105.79 +ship) RAYBESTOS 881H680026E3 Element3 Rear Kit ($86.79 +ship) This setup has coated rotors and uses hybrid pads. In general, hybrid pads stop faster then ceramic pads but last longer then...

    Disconnected ABS Module; False Engine Failsafe Mode?

    It is difficult to track down what is needed without knowing more about your truck. The following should generally always be posted when asking a question 1. Year 2. Engine (4.0L, 4.6L, 4.0L Flex) 3. Drive train (4WD, AWD, RWD) 4. Trim Level (XLT, XLS, Eddie Bauer, Limited) It's a good idea to...

    Running Rough

    Whatever you decide to do, I would replace the spark plugs with the correct Motorcraft plugs and make very certain that the spark plug wires are connected correctly to the coil pack. The diagram posted by TechGuru is not what I would have expected for a v6, so check what you did very carefully...

    Running Rough

    ^^^^^^^ This is very good advice to pay attention to. If you can't get it running properly you may want to rethink putting any more into it. Do you have the ignition sorted or is it still acting up? It is always good to know about lower cost parts that people have had good success with. This is...

    Running Rough

    I would probably try to sort out your ignition issues before sinking allot of money into your suspension. At the very least, do as TecuGuru suggested and double check the order of the plug wires. I would probably also change out the spark plugs as well. As far as the wheel bearings go, there is...

    oil pressure gauge dropping out, again, 2002 XLT 4.6L 4WD

    Well I think I am done with this for now. I have come to the conclusion that the issue is that the oil pressure sender is overheating and this causes it to shutdown. I got information at another site indicating that the hot idle oil pressure should be between 25-30 PSI. Mine is above 30, so I...

    Running Rough

    I know it can be very frustrating to make repairs and find that the parts you used failed, or were the wrong parts in the first place. This is really just an unavoidable part of doing your own repairs, at least from time to time. It can help a great deal to post here before buying your parts...
