Ford Transmission :: Transfer Case Removal Front Driveshaft Seal Is Leaking And Gasket Failed
May 15, 2013
I had my truck at the shop today and it was determined that the transfer case front driveshaft seal is leaking and the gasket between the transmission and transfer case has also failed. The shop wants a reasonable amount to fix it but they need the truck for 2-3 days. It doesn't appear to be that difficult of a job to remove the transfer case. Am I missing something? Dropping off the truck and leaving it for a few days is the difficult portion......if they could do it in a day I'd just pay them and be done with it. So my thought was to pull it and just drop it off so they can replace the seals and fix any other issues.

I just changed transfer case fluid on my father's F-350 for the first time in 13 years. (over 230k). Removed fill plug first and fluid gushed out of the fill hole unexpectedly. Did not have catch pan ready, so made a mess. I thought it was just over filled form the factory, but too much was coming out to be simple overfill. Almost 2 qt came out of the fill plug.
Did some google search and found many Ford trucks have failed transmission output shaft seal and transmission fluid leaks out to transfer case, causing transfer case to overfill. I am yet to check transmission fluid level, but considering how much came out of it that probably is the case.
Now, how bad of the problem this really is? Will overfilled transfer case cause some serious problem? 4x4 is rarely used (once or twice a year in winter) on this truck and from what I understand transfer case doesn't really do anything in 2WD other than just passing output from transmission through.
There are no fluid leaking outside and repairing the seal would be a too much of work for me.
Also changed rear differential fluid for the first time and I was surprised how clean the fluid was. There were thin layer of black sticky residue (sludge?) covering everything, but the fluid itself looked clean and no visible metal shavings. I guess that is why Ford said it does not require change under normal condition.

I got a 97 f150 4x4, 4.6 and I had the shop replace the seal 3 times and it's still leaking, the seal where the driveshaft goes into the t case, I call it the slip yoke seal, they said the bushing inside looks good, there doesn't seem to be a whole lot of play in the driveshaft, it doesn't seem to leak a whole lot, I'm about ready to just forget about it and just run it, they put a seal from oreillys in, it seem to be leaking out of the bottom hole on the seal...

I found that my transmission was low on oil but couldn't find a leak. What I did find is that the seal in the transfer case was letting trans fluid transfer into it and then it would leak out the out put seal. I purchased the new seal and gasket and repaired it myself in about 3 hours. I removed the rear drive shaft and removed the front drive shaft from the transfer case alone or you can take it out completely if you want.
Drained transfer case unplugged wiring and one vacuum line. Unbloted from trans and removed using trans jack. The bolts are not the easiest to get to. i used a 3/8 ratchet to break them loose then used a stubby 3/8 to get them out because they are around 2 inches long. Once down I had to jack up the truck to get it out from under it. I removed the old seal and installed new one cleaned everything up and installed with a new gasket.

Noticed some fluid on the bottom of the Ex a few months ago and have been watching it since. Drained and refilled with the XL-12 fluid at the time and based on what I can see the likely culprit is the input seal on the transfer case. I have searched high and low both here and via the almighty google with little info to be found. Is it simply remove transfer case, replace input seal, reseal case connection, and refill?

I've got an E4OD trans out of my 1994 F150 4x4. It has 145,000 miles on it. The reason why it came out was because the front seal was leaking terrible. Also the electrical connector for the transmission melted and there is a hole right there now. Other than that the trans shifted fine and worked when I drove it. My question is what can I do with the trans?

I just changed the front seal on my transmission, but its is still leaking as if I never did a thing? Did I miss something or is there something else that could be causing my problem?

About 9 months ago heard a strange noise when shifted into 4 wd , sounded like driving over those grooves on the side of the highway to keep people awake.
Had to pull over to stop , as it would not go back into 2wd with the noise still going.
Then it stopped , after shutting truck off and restarting.
Then earlier this year after trying to do it again in 4wd had bad clunking noise and was hard to get back in 2wd , I can here the shift motor engaging and the dash reads in 4wd, seems its not engaging fully in 4wd and not going back to 2wd, its a very bad clunking noise, shakes the whole truck.

I have a BW 1345 transfer case. Does it have the shift in the fly capability? And, if so, what precautions should be taken if shifting on the fly?
Second, where can I get a "plate" or label that shows the shift pattern? I know the shift pattern, I just want to post it in my vehicle in case anyone else ever drives it and needs to use the 4 wheel drive.

I have a '95 F-250 7.3 auto 4X4. The transfer case linkage has been floppy and prone to coming apart since I've had it, but that's been fine for me. I let my brother use the truck last weekend, and now it does the following: When you put the transmission in reverse, or when the truck overruns the engine (compression braking) it grinds badly like the transfer case isn't quite engaged. Only does it in 2 or 4 Hi, and everything's normal otherwise.
Could the transfer case have jumped out of gear while he was driving it, and he didn't know to either push it into gear or pull it into neutral before it did damage? I really don't want to pull a transfer case in my driveway in December in New England, but give it to me straight.

On my 2007 f150 5.4 last week i changed out the driveshaft and it smoothed things out. This past weekend I dropped the transfer case oil and refilled it with motorcraft transfer case oil as per ford but now the front end seems to shake more than before. It just seems to come through the steering wheel but the wheel seems tight almost like a death wobble with solid front axles except obviously this truck doesn't have that. There are no leaks and I filled it up to the top fill hole with between 1.5 to 2 liters of oil until it started running out. I should also mention that when i went to check the level it was overfull on the top plug but it was that way for the last 90,000 km or so.

My 2000 explorer has picked up a clutch chatter when taking off with the wheels turned. It is AWD, and has an 8.8" LS rear end with and 173k on the clock. Is there any good way to tell where the chatter is coming from? I know how to check the TC clutch, but it requires dropping one of the driveshafts.
I may try changing the rear diff lube, as I am sure it's never been done. They say "lube for life" but no fluid can last forever, I would think.
Also, on that note... a couple years ago I had a pinion seal leaking and the shop said it was 2 quarts low when they fixed it and said "rear diff damage has probably already occurred" on the ticket. While that is possible i suppose, would think i would have major problems right away as the diff only holds 2.5 qts (IIRC). Least wise, that was probably 50k miles ago when I had it fixed.
More than likely, the mechanic was an idiot and it was only .5 qts low, as i'm 99% sure that they left the pinion nut loose when he did the job. (had a terrible vibration that mysteriously went away when i brought it back for them to find out what is going on .. they said they didn't do anything, but it was fixed when i got it back ... they don't get my business anymore)
Anyway ... would i be able to feel that clutch chatter with one rear wheel in the air and the trans in neutral? Assuming the worst case scenario, and the TC clutch is going out, how big of a deal is it? Can i get another 20K-30K out of it before it gives up the ghost?

I had the abs come on on dry pavement.. I changed the front ring gears,, Bought 2 new axles with ring gears all new on there.. fixed the issue.. Now i have a oil leak--transmission oil at the driver's side axle.. Is that the seal there in the trans that should be replaced? difficult? Why leak now if it wasn't leaking before..

So I am on my way home after an honest 8, and I make it a mile down the road and goose the old girl a little off a stop light. Well next thing I know we have smoke rolling out under the hood, well it turns out the "smoke" was r134 refrigerant. The guy that recharged it said that the compressor failed and that its common with retrofits because 134a runs at a higher pressure.
Now I don't need a/c, and I might just leave it as is, but it would be nice to have the old girl working 100%. It also turns out that the front seal of the transmission is leaking, I am debating whether or not to just have the transmission rebuilt. it shifts fine but its gotta come out anyway. Its a 700r4 and the trans guy recommends stronger 3-4 clutches and a shift kit to make the holding pressure higher.

I took my gs350 for a drain and fill today. Before They did anything, The service advisor called and told me the pan gasket is leaking along with a seal? I am aware of the gasket on the pan but wasn't able to get any info on the seal. Is it a seal that is replaced regardless of leak or not if they drop the pan?
Got quoted 700+tax for pan drop, replace gasket and said seal with fill of fluid.

After reading some posts I think my passat could have the cam seal and valve cover gasket leaking. I smell burning oil when stopped. How much should this repair cost if I go to an indy repair shop?

I'm trying to replace my transmission output shaft seal on my 2wd and I can't seem to get the seal removed. I couldn't find anything to rent from O'rielly's or Advance Autoparts that would work. It's in there really tight ....
