2 questions!

How common is a rear main seal leak on these trucks? Mine has 117,500 on it, and before it would drip a few drips when you shut it off, now it's a bit more extreme that I'm hauling with it, it drips when its running now, and is coming from between the transmission/motor area. My entire under carriage is covered with oil after 1600 mile haul.


Next thing, when loaded (and this morning it did it without the trailer) the "CHECK GAUGES" light comes on and the volts shoot all the way to 18v. what the hell is that all about? it just does it at randomn times, sometimes for a few seconds others a few minutes. Both batteries are new.

nothing comes up as I expected, there wouldn't be a code for a rms leak, nor the volt problem I dont think

Dying alternators sometimes spike like that. Sometimes with a dying alternator you will also notice wierd noises in your stereo system. I'd pull the alternator and run down to the local parts store and get it checked. Thats a bummer, and not a great ambassador for you and dodge. You seem to have had more than your fair share of troubles with the truck.

O'Reilly's is the cheapest around here at $149 for it with the core, I will test it here at the house tomorrow before I pull it out, I'm feeling kinda lazy.

The radio is making funny noises but then again my radio only works sometimes I think it may have a short or something




Sux no one has heard of a rear main leak on these motors. Kinda makes me wonder where I'm getting this oil from if it indeed is the rear main seal or not

Well, I would think that a rear main leak would've eaten your clutch pretty quick. I don't think they like to get oil on them If IIRC.
I would do some scouting around, and see if it isn't perhaps coming from between the vacuum pump and powersteering pump. The vacuum pumps on these trucks have a tendency to get leaky and it comes out from between the vacuum pump and powersteering pump, because there is a through shaft (can't think of a better way to describe it) that drives them both. That is a real common problem on these trucks.

Look around, hopefully its not your rear main, and something a like more common/easier to fix.

:iagree my truck had this problem and took it into the local shop to have it fixed and still leaked took it back they pulled it apart and the guy used the wrong seal so I wasted money on buying a vacuum pump because the guy working on it had his head burried. but I have a spart pump now..

Those Vacuum pumps aren't usually that cheap when a shop gets them for you either. I heard one guy say that a shop told him $2200 for a new pump. www.fixinrams.com has remanned ones for 400-500 somewhere in there. They also sell the seal kit for about $60. Thats the way I'm going when I do mine in the next couple weeks.
