C/K :: Front Diff Pushing Fluid Out - Vent Tube
Jul 30, 2012
My front differential on my 97 Silverado Z71 sometimes vents some fluid out of the vent tube. I end up smelling it in the interior while driving. The vent tube top is above the top of the radiator and has the little cap on it. The first time it did it, was during a heavy rain. I had it in 4wd on the freeway doing around 60-70 mph. I figured it was because I was in 4wd. It did it yesterday after a 35 mile drive on the freeway again, but I was in 2wd the whole time. Outside air temp was over 100 degrees and I am using Royal Purple fluid. I checked the level a couple of weeks ago and it was below the fill plug about 1/2 inch.

I was pulling a motorcycle trailer down the interstate about 75 mph for about 4 hours. When we got home I noticed it looked like there had been an oil leak. I looked underneath and it appears like tranny fluid spewed out of the top vent tube on the tranny. I have a 4x4 with a Automatic overdrive. It was tranny fluid and it does not appear that it was low on the stick when I checked it. We were pulling some hills and it would downshift but it seemed to be working fine. Seems to still work ok. We had the tranny rebuilt about 50,000 miles ago.

Front diff does not leak but seems to get alot of oil coming out vent hose. enough to make a mess and require more top offs.

I have a 2002 F250 SD 4x4 w/5.4. I drained the front differential gear lube and refilled with 2 qts of gear lube as specified in my owners manual. Actually the manual says 1.8l / 3.8 pts. The fluid level is not up to the fill hole and if I stick my little finger in the hole I can barely get any on the tip of my finger. The owners manual says these capacities are for F250/350 w/ Dana 50 axle. It then says F350/450/550 capacity as 2.7l / 5.8 pts with a Dana 60 axle. My question is should the fluid level be up to the fill hole, as with the transfer case and rear end levels? Could I have a Dana 60 with the higher gear oil capacity in my F250? Whats the proper gear oil level?

My 2000 Ranger has been leaking fluid around the front Diff cover so I decided to pull the cover and reseal it. It was obvious that this was going to be a tight job but I didn't anticipate running into a bolt that can't be removed because interference from the front cross member.

My 98 mountaineer keeps throwing rear end oil out the vent tube.. Why does it keep doing this?? its been doing this for a while and had to change an axle seal, I think because of this. It stopped doing this for a little while after I changed the seals and put in new oil.. Its not over full.. When it stopped I figured it was because the oil was old and was foaming or something.. But now its back to doing it again... The tube is not plugged.. Why does it keep doing this???

I decided to install a new Optima yellow top battery because I performed the battery check and found the voltage low and therefore believed my 2008 was still running on the original OEM 12v battery. Much to my surprise I found a non-OEM battery installed and the vent tube elbow missing!

I have a 1999 Chevy Silverado 6.0 Ltr C2500 Auto tran Large Gas tank 120,000 miles. My gas tank filler tube vent hose has come off of its attaching point. It is still connected to the filler tube. I can not see where it connects on the other end. The small hose is long enough to reach the rear bumper on my truck noticed it hanging over the differential on the ground. Where to reconnect it to. I do have a check engine light showing. I fear my truck is falling apart slowly.

Ok, I have a 98 F150 XLT, standard cab, 8 ft. bed, 2WD with limited slip - if any of that makes a difference.
The rear axle vent tube is literally blowing oil out the top, where it's loosely connected to the bed. It does this every few weeks. I pulled the hose and ran a rifle cleaning rod down it to make sure it wasn't plugged ... it wasn't.
It seems like it's building up pressure somewhere, then blowing all at once, but why?

I own a 2004 F-150 FX4 5.7L V8, I notice this morning that I had gear oil coming out of my rear Axle Vent Tube. What would cause this issue? I'm kinda at a loss as to what would cause it.

Drove my car for the time in a week, i picked up a 89 gli 16v, and when I shut the car off and was getting my backpack out of my trunk i started to hear like a weird noise, kinda like a pump was pushing fluid or air from the rear of the car, it did it for about 20 - 30 seconds then stopped. No cel light and only a lil over 50k on the car.

While I have routinely seen a little fluid seep from the bottom/back of a Rear Diff, I have never seen it from the front where the drive shaft enters.....until I looked under my '12 F150 yesterday. Have any of you had this problem on your truck? It is at 86,000 miles. Mostly highway, with some 3000lb towing on weekends. I may have until failure?

I am changing the rear Diff fluid in my 1999 F250 Super Duty with limited slip differential. I have read in the manual that 8 ounces of friction modifier is required, ford dealer said it only required 4 ounces. I bought 8.
Also I asked for a inspections plate gasket and ford said use silicone... When I removed inspection plate it had a gasket. So, silicone or gasket or both? Differential capacity is 6.9 pints 75w/140w synthetic.

I have a F-250 4WD with 7.5L which has a MC/Holley 4180c sitting on top. It was getting very poor mpg (like 5-6 miles/gal) and then was getting harder and harder to start. This progressed rather quickly to not starting with fuel coming out of the primary vent tube. I suspect it has to do with the primary float stuck open. I was considering rebuilding the carburetor. Is this over reaction prematurely or is there something like float adjustment that may rectify all of the symptoms described. If a rebuild is in order what is the information I would need to ensure getting the correct rebuild kit. Info that I have so far from research is it is Motorcraft ID #E5HE-9510-MC.

I just picked up an 09 F250 a couple of weeks ago and I was planning on replacing all the fluids since I'm not sure when everything had been done in the past, but it did pull a camper 5th wheel. It has about 93000 Km/57000mi on it
One thing I noticed when reading the manual is that a rear diff fluid change is not necessary on these rear axles unless they have been submerged in water or repaired etc..
Just after I got it I noticed the pinion seal was leaking. It was fixed under warranty but the dealer did not replace the diff fluid as they said Ford will not pay for it.
My question is do you think I need to replace the diff fluid or should it still be good, given the relatively low mileage.

just found out about this a few days ago. It seems that the leak is between the fluid container and the tube. I just used some zipper to tighten up the connector. Where to buy this tube and the steering wheel fluid, and how much are they? My car is a LE V6 2007.

I have the 4r75e transmission. Last week I was driving for about 20-30 mins when my transmission fluid started to boiled and came out the dipstick tube. I let it cool off then took my time and drove it home. I know my transmission is not shot because I am getting full power on the transmission. After I got home I checked the fluid level and it's good, then I disconnect the transmission fluid lines on the transmission to see if I am having flow, but no luck...
I took my air hose and blew the lines out and they were clear. I also blew into the transmission thru the ports where the lines were connected. I started the truck up and the fluid came out with full force about 1-2qarts came out before I shut the truck off. I was all excited and I connected all the lines And started the truck to go for a test drive but my gut told me to disconnect the line to see if I am still having a flow and as suspected no flow...
I took off the lines that connected to the transmission and still no flow. I blew the air into the transmission again and started the truck up and bam I have flow again for about 20 seconds... I shut the truck off and I decided to connected the lines back to the transmission and I disconnected the lines about 12" away from the transmission to put a clear hose that connected both lines to make a loop.
Started the truck and there was no flow, I disconnected the 5/8 nut on the transmission and blew the air into the transmission. Started the truck and only got a few dribbles. I check the fluid level and it's still good. I am stuck and don't know what to do... What part of the transmission send the hot fluid out to the cool. The valve body? The main pump? The solenoid???

I now purchased a 1997 Ford F150, I bought it with the past owner saying it needs a transmission but it drives nice until I get to about 35mph, at which point it feels as if the front diff is stuck in 4wd and it shakes violently, I have read other forums and was hopeful that it was the transfercase issue where you take the transfercase motor off and turn it into 2wd manually and it didn't seem to change anything, it sounds like it is trying to change from 2wd to 4wd high and then to 4wd low, but it doesn't seem to sound like it is actually changing anything, the turning on dry pavement does change after switching it but it still shakes and feels like the front end is keeping it from being in 2wd, as I have done very little work on Fords, in the past and I do like the feel of this truck and would love to fix it myself and not take it to someone to have it fixed.
