    Blend door rotation question

    Last spring, my actuator started clicking, so I unplugged it and, thinking it was a problem with the blend door, I got the doorman replacement. Last week, I decided to replace it. First, I took out the actuator and it looked fine. Check the top of the door where the actuator fits in, and it...

    5.0 engine ticking question

    Now that things are starting to thaw here, I took some time this weekend to replace the passenger exhaust manifold. A few months ago, I picked up a pair of used cast iron manifolds. Finally, pulled the passenger tubular manifold off yesterday, and, found a series of fissures on the #4 exhaust...

    5.0 engine ticking question

    I replaced the offending lifter with a new one, and I still have an issue with the #4 intake being loose. So I am guessing that the cam has some wear on it. Could I go to a slightly longer pushrod, like 6.30 to compensate for the cam wear? Might need a longer pushrod and shim to get the...

    5.0 engine ticking question

    OK all, I am back at it! Searched for the source of the tick, including listening as best I could for an exhaust leak, but it just sounded like it was coming from the passenger side valve cover (using my stethoscope). Sounded like a bit of a rattle along with the tick around number 4 cylinder...

    5.0 engine ticking question

    I have the tubular type manifolds. I have heard and seen a few cracked cast manifolds, and they were pretty obvious sounding. Will the tubular manifolds on 5.0 really sound, to me at least, like a mechanical valve train issue? The noise does change, going from fairly loud to almost quite, but...

    5.0 engine ticking question

    I am definitely going to check the rods for straightness, along with length. Don, the rockers are stock. I thought I could just bolt and properly torque the rockers, but have read, I think on the corral, that you should rotate each cylinder so the valves are closed, then hand tighten, then...

    5.0 engine ticking question

    Just got a stethoscope and went through the engine. I don't really hear much noise other than what seems like normal rotating valvetrain sounds when I stick the end of the stethoscope on the head and valve cover. However, one of the injectors, right where I thought the bad lifter noise was...

    5.0 engine ticking question

    I've got a GT6. They come with a lump of a straight six. Sounds nice, but is too long for the chassis, so sits forward and high, at least as they came from the factory. The 302 fits perfectly, weighs less, and lowers the center of gravity. Always wanted an MGB-GT, love the looks of them...

    5.0 engine ticking question

    Perhaps not the best pictures, but here are the rollers I took out. Most have some lines/scoring. I did prime the new lifters by keeping them in fresh oil overnight. When I started the motor, I expected some lifter noise as the oil pressure came up in the lifters, but other than the one tick...

    5.0 engine ticking question

    OK, a question for the 5.0 experts on this forum: I had a lifter that collapsed and would be pretty loud on startup, but then would quiet down after a bit, but not completely in my 98 V8 explorer. I did drive it like that for a while, maybe 2-3k miles. So, I figured I would replace all the...

    Dash issues...

    Concerning the radio, it seems to be an issue with most of the Pioneer radios Ford used in that era. My 98 had the same issue with illumination. I got a slightly newer "Alpine" unit from a Lincoln as a replacement, which works with my steering wheel buttons, CD changer, and Sub. I just...

    How many miles on your 2ND GEN EX?

    I just looked at the odometer on the way into work this morning, it was right at 373,734 miles. Has its issues, but I drive it most days. Pretty sure the transmission has been replaced before I got it as it shifts way to smoothly for that mileage. Engine runs pretty well, but I need to change...

    Tighten your caliper bracket bolts!

    I just went through some brake rattle noise issues after changing my pads. Turned out that one side was missing the anti rattle clip which I didn't notice when putting the new pads in. That took care of most of the noise in my front end, along with a bit of brake jutter, but the caliper still...

    AWD transfer case issues/noise

    After doing some research, I am going to pull the front drive shaft out again, and take the u-joints off and apart to inspect them, and at the same time, I will check the cardan joint. From what I can tell, there is a ball/cup inside that can wear and make noise.

    AWD transfer case issues/noise

    Well, time for an update.... I ended up replacing both carrier bearings and outer differential bearings on my original front diff. I did not touch the pinion bearing as it felt quite nice. It turns out that the carrier bearings were very worn with pitting on the races. I carefully set the...

    AWD transfer case issues/noise

    OK, thanks for all the help guys. I think I am going to go ahead and pick up a good used diff. I might rebuild my existing one at some point. It doesn't seem too difficult. I pulled the carrier out, and placed it on my bench on the carrier bearing side and when I spin it, I hear the exact...

    AWD transfer case issues/noise

    Just called the only local yard, and they have 5 diffs. Price is $210, which includes inspection and reseal. They will not sell one with bad bearings or gears. That seems reasonable.

    AWD transfer case issues/noise

    Don't all the non-AWD explorers have the vacuum servo stuff on the right axle shaft? Or do they control the engagement in the TC?

    AWD transfer case issues/noise

    OK, decision time. I've inspected the front diff, and it looks like the carrier bearings and pinion bearings are fairly worn, along with the side axle bearings. The result is a pretty sloppy pinion to crown interface. The good thing, the gears all look good, and there wasn't any real metal in...

    AWD transfer case issues/noise

    I now have the front diff out. There is an excessive amount of backlash, but the wear marks look good on the crown teeth. The spider gears feel tight. I am pretty sure that the passenger side bearing where the CV shaft slides in is bad. I don't hear any noise in the bearings inside the axle...

    AWD transfer case issues/noise

    OK, I am still chasing that humming grinding noise that was still present after removing the front shaft and replacing both wheel bearings. I put the explorer up on jackstands (still no front shaft), removed all tires, and started it up and put it into gear. Then I went around to listen for...

    AWD transfer case issues/noise

    I did check the front diff a few months ago, and it seemed clean, but I'll check it again, maybe even change the fluid. The only real leak in the area is coming from the oil pan, and that is really bad.. What do you recommend for the front diff? Now, shouldn't I be able to hear a bad bearing...

    AWD transfer case issues/noise

    So, I have been driving without the front drive shaft for a few weeks (not every day), and the noise is still there. I feel like it has to be the tires, but I am not in a position to replace them at the moment. I did rotate them, though. They are M+S tires with cupping on the inside due to...

    AWD transfer case issues/noise

    Quick question, would I be able to spin the front output shaft off the TC (front driveshaft removed) by hand while the transmission is in park, and the rear driveshaft is still installed and the park brake is on? Right now, I can move it a few degrees back and forth, but it kinda sticks at...

    Thank you, thank you, thank you!

    I agree! Lots of great info here from simple maintenance to extreme mods.
