The (stock) rear end of my 63' Impala is again leaking diff oil from 1 of the beam oil seals. Back in 2002 I had the consummate diff reconditioned with new bearings and seals throughout because when I bought the car the RH axle seal had a bad leak. I'm afraid to say that information technology has begun leaking once more, and the car would not take washed 5000 miles since the diff was rebuilt What is the most likely crusade of the axle oil leak, and what can I do to prevent the side by side oil seal I get installed from failing over again?

Yous might want to pull this apart and wait carefully at the o-rings, and where they ride in the housing. At that place have been several guys on here who take had problems with the bearings spinning in the axle housing. This would certainly ruin the o-rings, and a sloppy fit would make information technology leak. Email Report

Often times (over time) the seal will wear a groove in the axle and it will never seal good again. Email Report

The seal surface on the 1964 and earlier was the bodily wheel bearing. I observe it difficult to imagine that a new wheel begetting (less than 5k miles) is leaking at the wheel seal. I recommend you lot closely examine the axle housing (the surface that the o ring seals against). It is either burred, gouged, or rusty causing the echo failure. This surface can be reconditioned with a brake wheel cylinder strop. Any gouges can exist filled with epoxy, then rehoned. I hope they are lubricating the o band on the wheel bearing prior to installation - and not using a sealant..... Email Report

Our buddy mtwallet is fighting this same predicament but he was lucky enough to find replacement USA fabricated bearings (with O rings) on ebay for most half the cost of NAPA, etc. To a much lesser caste the lube could be passing through the bearing itself due to improper handling at installation or seal failure. Do check the axle tube I.D. and make certain it'southward smooth or it volition ruin the O rings at installation. impala 61 Impala Convertible, AACA Senior M National 99 Jaguar, XK8 thirteen Avalanche LTZ 18 Equinox E-mail Report

Well the RH axle bearing/oil seal had partly destroyed itself which explains the bad oil leak Unfortunately the axle housing surface is scratched & scoured which will require it to be honed slightly to clean it up. The cause? The RH axle had a slight curve in it This was not picked up during the last diff rebuild, probably because the mechanic was slack which is more and more than common these days when it comes to mechanics. I'm currently attempting to source a replacement (straight) RH rear axle every bit I believe once an axle is aptitude it's never as adept after beingness repaired. And then for at present my 63' sits in my guarage with its donkey up in the air with both axles out whilst I sort this mess out. Hopefully past adjacent week I would have found a new one and I can get this unequal upshot sorted once and for all. The trouble is the wifey is getting grumpy as the smell of gear (unequal) oil is slowly making its way into our house. Oh well, you lot become that! Regards, Greggy - 1963 Impala 383 PG Email Report

This causes the bearing to wobble and every bit a outcome, causes the seal to leak. You lot will NOT fix the leak until you supplant the beam, PLUS, it will eventually impairment the center section (if it hasn't already)! The 59-64 axles are all the aforementioned. E-mail Study

They really are non that expensive and are a ton better. Finding a used beam that is 40+ years old and has a gazillion miles on it merely doesn`t make sense IMO,,,, dq Email Report

If you're non going to race the car, why not find an automatic transmission equipped '59-'64 in a junk yard that has no signs of side impact and spend maybe $twenty. for the beam, another $60 for a begetting, and use it forever. Information technology may be a lilliputian off topic, but I used that unproblematic (cheapskate) philosophy when I raced way back when. I figured if I put in a set of unbreakable axles that had no "cushion" to them, I'd but break the centre section. And so I used the junk yard beam method. I permit the axle cushion the launch shock and never bankrupt a center department. Using a direct border, I scribed a directly line the length of the axle. I'd pull the axle after each weekend and check the twist. It would twist one-half mode around before it would break, and so that'southward when I'd put a fresh one in. Usually got 2-3 weekends out of a left i, and twice as long out of a right one. Verne Email Report

Of class new beam bearings were used after cleaning up the inner axle housing surface with a mild hone. I'll be keeping a close centre on the leak indicators on the inside of the backing plates, simply I recall nosotros've nailed the oil leak problem one time and for all. Its good to have the old 63' back on the road again, even though information technology was hot (most 40C) today Regards, Greggy - 1963 Impala 383 PG E-mail Report
