I currently have the rear axle shafts off the truck. I took off, cleaned then put on the rear diff cover.
I live in an area that does nothing but form rust anywhere and everywhere in very little time.
I don't want rust forming in the rear diff gears - can I fill the rear diff up ? Or will it leak out of the rear shaft holes ? Can I fill it up halfway then ?
Had oil seal failure on the rear differential at 35,000 miles?
View 6 RepliesI took the front axle shafts out a couple months back and remember NOT seeing any differential fluid in the axle shaft housing. But then when I took the tire off tonight.. I noticed diff fluid leaking from from the axle shaft dust seal ?
1. I didn't think diff fluid flowed up near those front dust seals ?
2. That's a brand new dust seal so I'm guessing some debri must be in the connection causing the leak ?
I was getting ready to replace the carrier bearing and noticed the rear pinion seal is leaking. Before attempting the replacement myself, I would like some opinions on the noise in the video below. Is this normal? I am confidant I can replace the carrier bearing and pinion seal, but not sure I have the tools for anything else.

I am a new 6.7 owner and had/ have a 7.3 As I have been getting to know the truck I have been under it and noticed that the front drive shaft and axle are locked in. My hubs are switched to auto but I know on my 2000 7.3 when my hubs are on auto my front axle and driveshaft are disengaged... I'm wondering if the new 4x4 system is different. I know that can save on MPG
View 6 RepliesI have a 2012 f150 supercrew with the eco boost. While driving down the highway my rear tire passed me. After crashing I looked at the rear end and the wheel and hub had broken off of axle. Scared the crap out of me. Would this be a warranty issue?
View 14 RepliesThe rear axle in my dads 1998 ford ranger has been vibrating for quite a while so I pulled the cover today and found that the fluid was full of metal shavings, it was glittering. I also found this metal chunk in the differential so my mechanical experience tells me this is not a good thing. I am taking it apart tomorrow any tips or do's or don't? Also, what this metal chunk is and what that knurled up end is??
Door tag told me it was a 7.5 open 4:10 axle.
I have noticed a few drips coming from the rear axle input shaft where the drive shaft connects. It has only done it once and there is no residue on the trailer hitch so I know it didn't dump everything on the road. If change this seal, how difficult is it and do you have any information which might make it easier.
View 14 RepliesThe rear differential on my truck has been whining for the 2 years I've owned. The fluid has been changed but of course that didn't really solve anything. I'm trying to decide if I want to rebuild it. Was looking at buying the USA Standard brand rebuild kit, ring and pinion, and axle bearings and seals. How hard would/will this be to do myself?
View 4 RepliesToday I took the bed off of my 99 ranger. I was sitting on the cab looking down at the rear axle noticed the drive shaft was not entering the rear diff perfectly straight. As I looked further into it, I noticed the distance between the rear spring on the passenger side tire, is noticeably different. To visualize it, the wheel, at the bumper side of the axle, has a shorter distance between it and the leafs than the cab side. Not massive, but a few inches, and it's noticeable now that I can stand over it. I'm beginning to be very annoyed by this truck and it's previous owners, whom I take it , scammed my brother quite well with a $5k tag for a truck with so much not right with it. It's about to become my yard art for awhile.
View 8 Replies...when changing the fluid and RTV'ing the rear differential cover?
Usual suspects: Brake cleaner, Simple Green, soap and water, gasoline, etc.
I've never serviced one, but figure it is like this:
1. Drain
2. Remove cover
3. Spray, clean, rinse, whatever all the innards
4. Wipe and dry
5. Inspect. For what, I have no idea
6. Black RTV cover back on, replace drain plug, remove fill plug
7. Refill with 75w-140w Mobil 1 Synthetic (not sure what it is, but I looked it up here some time ago and bought enough)
8. Fill to within a finger tip's dip in the fill hole
I've had the RTV and oil for a while, but it's supposed to hit 59F here on Saturday with no rain!!! Time to crawl on the floor and get it done.
I didn't see any problems with my cover, so going to forgo the new aluminum finned cover this time
Guess the biggest question is what should I use to clean/flush the rear end?
This is 2002 Excursion WITH LSD rear differential. 4WD.
I'm trying to figure out what axle I have on a 2002 f350 single wheel 4x4 so I can order a replacement seal. So this morning I got to work and noticed that am oily guild was dripping from the front of my rear differential where the drive shaft hooks into it. I figure it the seal, so when I went to look up the repair kit they list several different axle options because of gearing, what axle I have as there wasn't a in owners manual with the truck. Who can I find out what axle I have so I can buy the repair kit for it...
View 5 RepliesWhat Spicer Part #s for the rear u-joints would be? I'm not nailing down the right one. I keep finding numerous ones, 1410, 1350, 5-160....
View 8 RepliesMy truck (02 7.3L cc) started making a grilled ding type of vibration when I would let if the throttle. I felt the axle going into the rear differential was a bit loose, so I took the cover plate off. The pictures below show where the pinion I think is hitting, sort of like the bearing is allowing front to Rear differential scaring from movement. Rear movement.
How difficult is a rebuild, and is there anything I should be careful of?
My wife has been complaining about a noise from her 2005 expo.
As she drove the truck today I have narrowed the noise down to the right side of the half shaft. From looking underneath and comparing what I was seeing and hearing, the track bar is not centered. Its more in on the driver side and out on the passenger side. I had her to stand on the running board and shake the truck.
I can definitely hear a kinda cluck? It sounds like the half shaft going to the tire but at the same time the bushing on the outer tire rod end. I can't determine what it is exactly.
when you rock the truck you can definitely hear it. Its not like violent loud but i'd like to get it taken care of. I looked for some grease points but I don't see none..
2nd question for the grease points that I do see how much do I grease it? how many strokes?
I picked up an '01 F-350 standard cab and bed plow truck for parts and am preparing to swap the rear axle into my E99 F-250 SB unless someone gives me good reason to just swap the carrier. I want the LS differential. I will also do hutch/harpoon on the tank so I figure that bed removal will make both jobs easier. Once I have both beds off I can give things a visual and see what lines and cables need to be changed out as well. I believe that there is a difference in the passenger's side caliper but I am not 100% on that and I don't know what I will need to change if anything. I am hoping that my drive shaft will remain.
Thus far I have gotten to rotted bed off of the donor truck. The bolts would not come out and I had misplaced my cutoff wheel so out came the torch. In the process of blowing the heads off of the bolts I also blew some holes in the bed but didn't care, it's scrap. Fortunately I did not blow any molten steel onto the fuel tank. I was able to lift the bed far enough to reach the light plugs in the rear and disconnect them without damaging them. The large one that is still attached to the frame goes to the trailer lights and could have stayed connected. The two smaller ones with ends up feed the tail lights and license plate lights, they have to be disconnected.
The bed is shot so I just hooked chains into the rear pockets and drug it off with the front end loader. I did have to get off a couple of times and unsnag it from the frame. Oops, and to cut off the fuel tank fill and vent hoses.
The bolts are extremely rusty and wouldn't budge so I cut them off.
The organ recipient has a spray on bed liner that I had to cut through to get to the bed bolts, the heads look like new and the bolts look like they will all come out for me.
And this is what the nuts and clips look like that mount the bed to the frame.
Yep, there is plenty of rust.
Also, I found two safety cables wrapped around the bed frame and main frame mid bed that will need to be disconnected before bed removal. These are on the E99 SB only, not on the '01 standard bed.
Well I just noticed the rear axle air vent and it is blocked.. I ordered a new one and will replace it once it arrives.. what can I expect once I replace it?
View 2 RepliesI am on the fence with getting rid of my 7.3. Here's why. Whenever I crawl underneath the truck or look under the hood I see all these different oil/fluid leaks. She has less than 200k miles and I use her to tow my boat to go fishing.
Right now I am trying to weigh if the truck is worth keeping or selling and then getting a new/newer truck.
Here are some leaks. One is obviously oil and coming from what I guess is the front main seal. I really don't know. The other leaks going onto the U-joint look like oil leaking down the axle from the front differential.
I'm growing a business and not sure if I have time to play mechanic. However, everyone I talk to always exclaims, "You got a 7.3?! You luck SOB!" and I am kinda getting the feeling letting her go would be a mistake. FWIW, she is paid off.
Other than a slight wobble in the steering wheel at speed, she runs like a hoss.
Well, get the engine running sound, then the drivetrain takes a crap on me. . . On my way home, about 60mph. Hear a noise from front drivers side. Gets to the point where I think I am losing a tire. Got out and checked the lugs, all clear. Got back in and the truck wouldn't move. Shifted thru all the gears, nothing.
Revved up to 1500rpm and it just sits there and shakes, like it wants to go but can't. No grinding or anything. Got a tow truck and as we were loading it, noticed that the front axle was rolling fine, but the rear was dragging. Tried it in N and D and it still wasn't rolling. Also observed drips on the flatbed and the drain plug on the transfer case was wet.
Praying that it is transmission, cuz I can just have them come get it and have it repaired under warranty. Heck its only got about 3500 miles on it. If its the hat to check? Ill be spending the rest of my evening on YT/Google. . . (Figured this was the right area to post this, cuz its a 99 7.3, I didn't see a dedicated drivetrain area so. . . )
Can I re-use this shaft or is that ring around it no good. The ring is around where the bearing sits. It is a circumferential hump all the way around.
View 14 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?
