This part is necessary to keep internal pressure equal to the outside atmosphere. Thus, as the internal temperature of the differential warms during use, any expanding heated air is vented and no pressure occurs. This saves wheel and pinion seals from leaking. After many years of use, many vent assemblies were accidentally removed. Now, the small hole that once held the vent assembly is able to take in water. This is certainly not good for the internal differential parts. If the cap is still present, spray under cap with PB Blaster and make sure the cap turns freely. The cap does not come off.

I looked at the rear end over the weekend and found no vent as mentioned above. While I have no doubt 'some' trucks must have come with a vented rear end, it appears mine did not. Thanks again HL, I'll take a look tonite. | | | | | Joined: Jan 2001 Posts: 5,320 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,320 | Some early years had the vent half way up the torque tube, but all had a vent.
