Can't seem to unearth a definitive answer to this one, so here goes and apologies for the repetition:
I have an oil leak (EP90) from the splined shaft (halfshaft), driver side rear of my early 90 (drum braked rear axle). It's definitely EP90 and is definitely leaking from the splined shaft end and into the moulded centre/dust cap. As a result, oil is escaping from the dust cap and showing on the outside wall of the rear tyre.
Common opinion seems to point to a failure of the hub oil seal (RTC 3511), but mention is made of other possible causes. Could it be anything other than failure of this seal?
I did replace this seal last year (Corteco) when checking the hub bearings and, having just removed the complete assembly from the stub axle, noticed that the inboard facing lip spring had become unseated from the seal itself.
There again, I do recall these seals being quite fiddly to fit — especially getting them properly seated on the stub axle assembly when reassembling the drum and hub components. It is almost as if the process of tightening the axle nuts compresses the seal against the stub axle, thus unseating the recessed spring.
Anyone able to help?
Thanks again in advance.
