It is hard to replace a Differential seal? My differential started leaking after a garbage bag wrap around it while drive home. i was able to removed the tangle plastic bag but i notice leak after driving the car. Does anyone know a step by step fix procedure or a link. thanks |  |  | | 11-11-2006, 10:19 PM | #2 | | Senior Member Join Date: Dec 2004 Location: Northern New Jersey Posts: 395 | It's not a hard process

It's not a hard process, and fortunately for you, the gasket is between 3 and five dollars from BMW. Follow the directions for the fluid change, but when all the fluid is out, unbolt the cover and replace the gasket. Then you bolt it back on. Few tools you'll need that arent common, but they're available at napa for a pretty reasonable price. Good luck. | | | | | 11-12-2006, 12:27 AM | #3 | | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 |
Your talking about which seal?
1. Pinion seal (Seals driveline input to diff.)
2. Axle seal (1 on each side behind CV joints.)
3. Diff cover seal (as described in previous post....)

If you are referring to the flange seals, I was gonna do them, but decided not to. Couldn't figure it out easily, and they didn't seem to be leaking, so I just popped the flanges in.

this is where the diff leak is coming from.  driverside axle seal. | | | | | 11-12-2006, 11:02 PM | #6 | | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 |
Those are the ones I bought the seals for, but never replaced. I think someone on this site "Cali-Ti" replaced them, when he did his diff swap. Quote: Originally Posted by ssprint this is where the diff leak is coming from. driverside axle seal. | __________________

bump. anyone else had the same problem? let me know thanks | | | | | 01-18-2007, 07:49 AM | #8 | | Senior Member Join Date: Jan 2004 Location: Northern Michigan Posts: 867 |
I'm bumping this..to see if the output seals are easy to do?
will the shafts drop once unbolted to the flanges? (I did this on an e21 lsd- the shafts are flatter though and dropped easily, flanges popped out easily making the seal replacement a breeze.)
the link above is for the cover gasket...
anyone done this on their own?

Are you referring to part #6?  I couldn't figure out how to replace them, or I would have done it. You will have to pop out the flanges, then get the lock ring out. REALOEM says there is a lock ring that holds the seal in. It just didn't look intuitive when I looked at it. If you need to replace it, then do the deed, it can't be too hard.
