My CA is leaking from two holes in the rear end (see below) I changed the fluids in it when i got it a few weeks ago, and I put in the specified amount. Since the fluid change its been leaking They look like factory holes (what they're for i have no idea)   ------------- WD , CA |

The pinion shaft seals are leaking. The seals are located by the differential housing. The final drive housings will need to be removed to gain access to the seals. Part #70232186 ------------- Thanks & God Bless Dennis |

I think the idea is to provide drainage so that the water that (inevitably) gets inside the housing has a way to get out. As noted, they're also handy for mice looking for a way inside the housings! 2x what DennisA said about your leak. The repair is fairly easy if you've got access to a hoist to handle the weight of the housings. I used an engine hoist when working on my CA brakes and hand clutch. There is some work involved to get to the point where you can remove a housing - removing the operator platform and the fenders. Make sure that you drain the differential before starting - otherwise there will be a lot of fluid running out the side of the differential when you pull the housing off! I say this from experience... ------------- WC, CA, D14, WD45 |
