Re: Rear End Pressure
I am very happy to see this thread. I installed a Volvo OD a few years back and have had a continued problem of oil being pushed out into the torque tube.
Re post #9: 1. The right side is passenger side? 2. What is "differential poppet vent? 3. What size plastic tubing? 4. Does the system vent only air (vapors) or some oil also? I finally see some hope of resolving my long-term problem. Thank you in advance. George |

Re: Rear End Pressure
I had a T5 installed and had pressure issues. Installed a vent in the axle to relieve pressure. Some say if you have an overdrive there maybe pressure issues because of the way the torque tube bolts to the OD unit.

Re: Rear End Pressure
Later axles all have vents. The rear axle creates heat/pressure as it operates. I would add a vent.

Re: Rear End Pressure
Oil level has a direct effect on heat as well,an overfull axle will run hotter,air dissipates heat better than oil.

Bill in Conn.[/QUOTE] Bill, This is the first time I've heard that the later axle housings have vents. Where are the vents located and what do they look like. A nipple and a hose or what ?? Thanks for your help. Al |

If one wants to disassemble the axle housings to drill a hole, this is one to use instead of tubing/ drilled bolts, etc. Last edited by duke36; 05-13-2019 at 09:32 PM. |

Re: Rear End Pressure
Duke 36 and Davew, thanks for the pix of the vents.
They make sense as I really think the extra pressure on the seals can be eliminated. Al |

Re: Rear End Pressure
my Tudor with a F150 overdrive has always had pressure in the banjo. It pushes grease out of the u joint housing. I an going to fix it before I take a trip this summer. I put a hole in a bolt and it puked oil. I am going to put a vent on th axle housing or the torque tube.I was told any vent should be outboard of the carrier bearings.
I am surprised my seals still hald pressure after 10 years and 26,000 miles. John
