Re: Torque tube seal-need a quick fix
I wonder what causes this it can't just be the rake alone as mine has a fair rake and doesn't do it. I drive almost daily with no problems. I have been parking on 1 1/2" ramps just to make sure when I get home but even before this it didn't leak either way.

Re: Torque tube seal-need a quick fix
I think the fact that I shortened the torque tube and took out the center bearing has a lot to do with it. Along with the rake.

Re: Torque tube seal-need a quick fix
I had some rake on mine at one time as well, but I believe with the natural incline of the torque tube and drive shaft, these two opposites canceled each other, and the oil did not backup in the torque tube behind the transmission.

Re: Torque tube seal-need a quick fix
I have a model A that always has pressure when you open the fill plug. I may have installed the front seal backwards and it holds the pressure. The only path for venting in all the banjo rear ends is through the transmission if the axle seals are good.
I asked hot rod works about this and they said they sometimes put a vent in the axle housing but probably not necessary. I wonder if this could contribute to pushing oil forward? John |

Re: Torque tube seal-need a quick fix
Hey Bassman,.....good ideas are just that, and when two people on opposite ends of the world come up with the same idea,....well.....it must be good . It may be a message to the original poster to give it a try. It may be a lot better than just putting the rear back together in haste, as it was before, just because the weather is getting nice and warm again. These are the challenges that the original, old skool, hot rodders had to come up with, probably on a regular basis, just to keep their "old iron" on the road.

Re: Torque tube seal-need a quick fix
I have a pretty good rake on mine and it does not ever have any issues with draining to the trans. I never park it on ramps, it has been this way since '09.

Re: Torque tube seal-need a quick fix
After driving the car for awhile feel the centersection and see how hot it is getting. Internal heat can force lubricate past the seals. On the original closed axles there was enough space for the heat expansion. With an open driveshaft modification, rake, etc, it can become an issue.

Re: Torque tube seal-need a quick fix
Hey Ralph M , quick question for you. You said the driveline is hollow, I get that as mine is as well. But , once the gear oil is inside the driveline, it there a hole anywhere else in the driveline for the gear oil to escape ?

Re: Torque tube seal-need a quick fix
I don't know if it's getting inside the driveshaft or not. I have not experienced any balance issues with it, but just to be sure I'm going to turn it straight up to see if anything leaks out Before I reinstall it. As was said before if that is the case then I might try some rtv on the splines to prevent it from doing that.

Re: Torque tube seal-need a quick fix
Don't put any RTV on splines..

Re: Torque tube seal-need a quick fix
I still wonder if an axle tube vent would help not push oil forward. I drilled a 1/16 " hole in a top banjo bolt for a vent. I took a 5 min drive and it pumped oil all over the place,so there is a lot going on in the gears.

Re: Torque tube seal-need a quick fix
Why is that? What harm could it do?
I'm talking about running a bead at the rear of the driveshaft where splines enter. I'm not going to take it apart and coat everything. BTW thanks to TerryOH looks like I have a solution on the way. |

Re: Torque tube seal-need a quick fix
I would be concerned about pieces of the RTV coming loose and getting into the banjo or pinion bearings, oil passageway etc. I don't believe it would make any difference in your oil problem as oil can get through the pinion roller bearings.

Re: Torque tube seal-need a quick fix
LOL, you can not have a vent anywhere near the centersection!! It has to be out near the center or toward the ends of the axle tubes. The gears are throwing oil everywhere in there and with a lot of force. The ring gear is throwing gear oil right at those bolts and it is under pressure to boot. I'm not sure how oil would get into the driveshaft itself, I would think the housing would have to be full for that to happen.

Re: Torque tube seal-need a quick fix
Keep in mind that all of the seals from the rear wheels forward must be installed to allow leakage towards the transmission rather than allowing pressure to push it into the rear brakes.
