I just came back from a long trip and during the 400 miles drive I started to hear noise coming from my differential - kind of like a constant high gear loud noise. I will hear this noise when I start to accelerate and it will only gets louder and louder as I go faster and faster. I had a pinion seal leaked fixed last week and I checked the fluid and it is full.
View 9 RepliesMy 1997 4.0 Rear Wheel Drive is making a clicking noise when it is put into gear or when it switches from drive to reverse and vice versa. Sound is coming from the back of van. Does not make noise all the time. Drove 50 miles last night with no problems and minimal clicking. Could it be U-Joints going bad? Or is this a different problem?
View 6 RepliesLast week I broke the pinion and spider gears in in rear end. Well Im getting a used rear end rather than rebuidling mine. What is the gear ratio on the 97 F150 xlt 4.6l 4x4. I figured they would all be the same but my tag is missing on my diff and I was told by an auto parts store that there were a couple different ones.
View 14 RepliesMy rear-end differential came apart and is not repairable. I have a 1997 F150, 2WD, 4.6L engine, 5 lug wheels. Which years have the same rear ends so I can scour the junk yards for a replacement?

View 4 RepliesSo I had the same , "noise" in the rear of my truck that i see other people having, at first I thought it was my tires, since I ran buckshots, so I switched over to street tires, and low and behold it sounded like I had buckshots still on the truck. So this thursday I pulled the diff cover off, and guess what i found!
The abs ring on the ring gear, was completely off , and the bolt that holds the pin for the spider gears was broken with just about maybe 3/8 to 5/16 of an inch left in the pin, right now i am still working on how to get that out of there.
also found a 1999 ford f150 2wd truck, 4.6 auto , that someone pulled a 1997 4.6 engine out of and put it in this truck and now it won't charge, and i think it's cause of the pcm needing to be reflashed. tested the alt, battery, everything is good, i just don't know if the pcm controls the charging system.
Pics will come soon of the differential destruction.
I have a 2002 f150 5.4 with 3.55 limited slip... For months now every time I hit a bump with the front right side there is a loud bang (sounds like a wore out bushing), and if I am driving slow at an idle you can here a thump every time the wheel goes around. And when I turn all the way it sounds more like a grinding sound.... The noise is getting very bad, what it is. I am very mechanically inclined but cannot figure it out.
Everything in the front end seem tight. When I lay under it if I get someone to spin te wheel the thump sound sounds like its in the front dif, kinda echoes through the front drive shaft but u joints seem good. I really think it's in the dif, and I'm hoping the banging noise I hear when I hit bumps is the same problem as the noise when the wheels go around....
I brought my 4runner in to fix a rear axle seal and to see if they could isolate a clunking noise I've been having. They said the clunking was coming from the rear differential (I believe him as that's what I heard, while driving or even just putting it into gear). They have yet to call me back, but any guesses here as to whether it is a bearing (my guess, as it is most pronounced on a bumpy road) or a cracked gear or something else. I've been driving with a clunk for about a week, but have various clunk problems for the last 80k miles ....

View 2 Replies2001 F150--V8-4.6-3.55--8.8. 221000 Miles. Changed front rotors and pads. Had scrubbing noise from right rear when applying breaks heavily. Changed rear rotors and pads. Still have scrubbing noise when breaking hard. I do not hear any noise when driving regular or when normal breaking. Differential fluid was a tad low. Applied fluid. Still have scrubbing noise. No leaks at hub seal or pinion. Bearings ? Maybe?
View 5 RepliesI have a 2009 f150 platinum and have been told both sides of the story now... that the front differential is sealed and need not be changed, and also that it is unsealed and can be changed. While asking this question I might as well lump in the rear differential as well. Are they both sealed or unsealed and need to be changed???
View 3 RepliesI need to replace the gear oil in the rear differential on my Ford F -350 and was wondering what the best sealer to use.
View 7 RepliesWell i picked up a 96 4x4 with the 4.0 a few weeks ago and been fixing stuff weekly that i find wrong. One thing i noticed was the rear diff was leaky but couldn't get the fill plug out so left if for now. Last night my wife was on interstate and it just started making a loud noise so she pulls over calls me. I get there and drive it and it makes a woowoowoo noise and it got louder as speed increased. She was 3 miles from the exit so i drove it about 15-20 to get it off interstate than another 2 miles to her sisters. We let it sit for a few hours and found a flatbed to haul it home, and when we finally got home i drove it off the flat bed and now it was making a loud clunky noise. Parked it in drive till today. Cracked open the rear and no fluid came out.
Inspecting all the gears looked good no metal in bottom so i went and got a new rear cover and 3 qt. of fluid. Put it back together and the woowoowoo was still there but seemed to slowly go away as i drove it around the block. So what else could be going on here or do i need to drive it and warm up the fluid so it circulates? I also noticed a sheeee sound like metal on metal when braking but i changed all 4 rotors and both pads last week but i noticed the brakes in the rear that look like drum brakes was bare but i assume that is only for the ebrake so didn't bother changing them yet. Could those be hitting the inside of the rotor and making the metal to metal noise?
I have a 99 F150 4x4 with the 4.6 Motor approx 150000miles. Transmission went out so I decided to try and replace it...
New/rebuilt tranny went in with no problem but something is not right. It will drive but seems like it is stuck in high gear and bogs the motor down. It is giving me error codes P1747, P0750, P0755, P0743, P0102. All the wiring harness is in good shape with no burns or other noticeable problems. Somehow the transmission isn't reading right?
When I bought this rebuilt transmission I was told it was set up for 2wd but he would convert it for 4wd. The only difference i noticed with the new tranny is the shaft coming out of the tranny, where the safety neutral switch is, has a diamond shape instead of the oval shape that connects the shifter cable. No big deal i think, just had to buy a new link for the shifter cable with the diamond.
Also on the passenger side of the tranny there is a nine pin plug. My wire harness from the truck has one pin hole that is opposite of the tranny. Not sure why. Do I need a new harness or wrong tranny?
I have a 2001 5.4 4x4 supercrew with 300,000 miles.. This truck is my baby. Recently when I start it up and after putting it in gear and begin taking off my engine is loud as if I am revving the engine without any indication in the rpms. I want to say it starts out on the trip a tad sluggish. Is there anything I can do to eliminate?
View 1 RepliesI have a 2001 Ford F-150 5.4L Supercrew that won't seem to shift out of 1st gear. This morning coming out of stop light on the way to work, the truck seemed to jerk when it was supposed to shift into 2nd gear. I was told by a friend that the speed sensor may be it?
So I took the truck around the block just so I can get a feel for what is going on. So the truck shifts into 2nd, but not past that. It seems that around 30mph the RPM's go up jump up quickly to 2k+ and no shift or increase in speed. I was reading up a bit on it and came across the possibility of a TPS?
Ok so I was going to just swap the whole rear end from drum to disk but it looked to be too much difficult;t. So the rear I have has 278,000 miles in it and its starting to make noise we were thinking about swapping the gear from the disk to the drum because the disk rear has 140,000 miles on it. Both have a limited slip. And 3.55 gears but i was thinking about getting 3.73.... So my question is can I swap in 3.73 gears into a rear end with the limited slip from one with 3.55 gears? Or do I need to buy a different limited slip?
View 7 RepliesI got my first truck about a months ago 2001 ford f150 v8 5.4.. has 155,000 seems to run good.. but about 3 days ago i started to notice that when I am in my driveway ill start it let it idle for say a min or so... then when I go to put it in reverse it will idle up for a lil bit.. it didn't do that till about 3-4 days ago.. other them that everything is fine.. should i get the transmission fluid flushed??
View 7 RepliesI'm replacing my rear diff cover and didn't realize there are multiple sizes. How do I figure out what the size is of my ring gear?
2001 F150 XLT 4x4 SuperCrew, 5.4L
Some of you may have seen my recent post about raising the X. Its about 5" higher in the rear. Prior to raising the X, I had a vibration at around 65 to 70 mph. It felt like a tire was out of balance. Go a steady slower speed or a steady faster speed and it would go away.
Since raising the X, the vibration is gone, which I thought was cool. But now I have a "grind" type noise coming from the rear. I have to do all the testing on the freeway. There are no issues, no noises at regular street speeds.
On the freeway, when accelerating fairly hard up a hill from say 65 to 80, I can hear sort of a rumbly, grindy noise from the rear. Its not really loud but I can hear and feel it throughout the cab. If I coast at around 70-75 mph (just keep the speed the same) on flat ground, I can hear it come and go when the X is truly coasting for a few seconds. If I get up to say 85 and let off the gas, I can hear it as I decelerate until I get down to around 65.
This all only happens between say 75 and 90. I get no noise below 65-ish.
I had the drive shaft out over the weekend. The u-joints had no play and were free moving. I did feel the smallest play in the slip yoke, so I gave it a good greasing. That didn't change anything.
I'm guessing the problem is in the differential somewhere. I have not pulled the cover off yet to check the fluid.
The problem started with a front seal leak a few months ago which I had no choice but to continue driving with because of low funds. I don't drive much so a couple of quarts of ATF was usually enough to get me out and about for what little driving I had to do. I know.. a front seal is cheap, but I'm partially disabled and unable to work on anything that is not under the hood.
I finally scraped up enough money to hire a friend to replace the seal, but he had a life crisis before completing the work, so I had to get another friend to reinstall the trany... still had the leak, but I could get around by adding ATF as before.
So we tried again... dropped everything and put another new seal on. This stopped the leak, but we got some grinding/squealing noises and could not get the trany to engage any gear.
From reading forum posts and other sources, we decided to replace the TC which we just completed this evening. We got some more of the grinding / squealing noise like before, except that it only occurred the first time we tried cranking the engine, the 2nd time we got no noises, but again no gears engaging.
What to check/replace next assuming there is something we can look at other than a total trany rebuild or replacement. I personally find it hard to believe we could have gone from a tolerably functional trany to scrap metal just replacing a seal and the TC. Its gotta be something simple we overlooked !!
