Re: [Chrysler300] Rear axle vent on a C

Hi Keith and all,
Definitely has a vent. It holds the brass “Y” block to top of housing where the brake line comes from front and splits off to the L & R side brakes. It is located about half way between the left brakes and center section. All Chrysler products for many years had it. Should not be hard to find. I doubt a Napa item.

A little help please?

I destroyed the rear axle pinion seal somehow on my C. Never leaked a drop before, and suddenly seemed to let go. I had replaced the gear oil a few thousand miles back, so that should have been rather fresh. But it actually smelled a little skunky now already, and that makes us wonder whether it may have overheated and destroyed the seal on a recent 3-hour 95-degree trip.

The mechanic noted that I do not appear to have a housing vent, and suggests the pressure buildup may have been a big contributing factor. I do think I may have a solid plug on the top of the axle tube somewhere.Should there be a vent on the '57 housing? If so, where? And is that a common NAPA part?

Thanks guys.

Keith Boonstra
