| | | Leaking u-joint or output seal? | Joined: Feb 2010 Posts: 1,215 old hand | OP old hand Joined: Feb 2010 Posts: 1,215 | I found this trail of fluid on the chassis, it looks like it either came from the tranny tail end or the u-joint or the driveshaft. Pattern says it does this while the van is in motion. | | | Re: Leaking u-joint or output seal? | Joined: May 2006 Posts: 3,113 Likes: 2 pooh-bah | pooh-bah Joined: May 2006 Posts: 3,113 Likes: 2 | my 75 has that same pattern. I put in new u joints and had the rear tranny seal replaced after I got it. I never cleaned it up however, maybe I should to make sure it's not still happening. sorry not to be any real help | | | Re: Leaking u-joint or output seal? | Joined: Apr 2012 Posts: 753 old hand | old hand Joined: Apr 2012 Posts: 753 | I would think its most likely the tranny seal. There isn't much fluid in the u-joint. Just a little grease. Lucky for you the seal isn't expensice and really easy to replace. All you have to do is remove the driveshaft and use a seal puller to remove bad seal and tap in a new one. Just be sure to put some grease or smear some tranny fluid on the slip yoke upon reassembly so you don't trash the new seal by burning it up.
When Chris Farley talked about living in a van down by the river, did anybody else think that wasn't such a bad idea?

As has been mentioned, there just isn't that much fluid in the u-joint, and it would be VERY difficult for it to leak out unless you had a crack in one of more of the u-joint caps. I second the suggestion that it is a rear seal, and I also think it could be fluid running back along the length of the trans until it get onto the spinning yoke and then is thrown into the bottom of the van. Check for leaks all the way forward.
Windows- they're what make a van worth owning! | | | Re: Leaking u-joint or output seal? | Joined: Feb 2012 Posts: 645 addict | addict Joined: Feb 2012 Posts: 645 | | | | Re: Leaking u-joint or output seal? | Joined: Feb 2012 Posts: 645 addict | addict Joined: Feb 2012 Posts: 645 | I do see some dirt rust colouring in the residue which would be from a failed u-joint cap seal, water contaminated and finally seal bursted. | | | Re: Leaking u-joint or output seal? | Joined: Apr 2012 Posts: 753 old hand | old hand Joined: Apr 2012 Posts: 753 | Never said I was always right. Once you pull the driveshaft out check the u-joint. Would be a great time to replace anyway. That just looks like a lot of juice. Specially when you think thats just 1/3 or it. The rest is all over the road.

I've never lost any tranny fluid, in my ownership.
That reminds me, I need a new cartridge for my grease Gun.
