BobT-47P15 Posted March 19, 2007 Report Posted March 19, 2007 Right rear, P15. Put that new old stock outer seal on not long ago. But did not replace the inner seal at that time. Did not seem to need it....didn't seem to be leaking any grease. Different story now. Wheel cylinder seems OK. So, guess it's time to pull the axle, etc. I have some inner seals I think are correct. Need to invent a puller for inner seal. Car show in a couple weeks. Those little blotches of red paint on the underside of fender.....original color....Sumac Red. Quote
grey beard Posted March 19, 2007 Report Posted March 19, 2007 Hello Bob, Before you pull too much apart, it may be expedient to first check the rear axle housing vent, to make certain it is not plugged. That is way easier than pulling drums, etc. I have seen many a good man led astray on rear end leaks just from a plugged vent. When they can't breathe and the pressure builds from heat and expansison, the weakest link will pop. Often as not, it's a pinion seal, but can show up any place. JMHO:D Quote
BobT-47P15 Posted March 19, 2007 Author Report Posted March 19, 2007 Thanks for the thought. At one time last year, I removed the vent and cleaned it up. It WAS gunked up and had been for years. I had the pinion seal replaced a few months ago. The outer seals I recently put in were NOS Victor Gasket Co items. The gasketing material may have been too old and stiff.....is it supposed to be more rubbery and flexible? Am going to try and locate some NEW seals first. Will check a couple local bearing distributors, and if they have nothing, I made a list of old car parts places to check. Quote
Reg Evans Posted March 19, 2007 Report Posted March 19, 2007 I just installed a set of the outer seals from Andy B on the 40 Plym. The inner flexible material was all dried up and didn't respond to a good soaking in light oil. One of the seals was even drilled off center. I can hear it squeaking on the axle. They are coming off today and going back to Andy B because they are junk. Another set arrived Saturday from an eBay purchase with fat and flexible seals so now I know what Andy's should have looked like. Another satisfied customer. Quote
Normspeed Posted March 19, 2007 Report Posted March 19, 2007 Bob, let us know what works for an inner seal puller. I'll need to do a right rear seal before long. The description of the "correct" puller in the manual sounds like something I've never laid eyes on. Quote
Plymouthy Adams Posted March 19, 2007 Report Posted March 19, 2007 Most bearing and seals can be bought per measurements in both standard and metric dimensions. Mic the item with a vernier caliper and proceed that way if you do not have a good number to cross match to. The John Deere tractor I have needed blade hub bearings, no part number, none listed in the JD catalog at the repair shop..so I just mic'ed and searched for it online...found the part number by dimension, bouth 20 on E-bay with ship and hand for about 25.00..that is enough to repair any of my three hubs ten times as it is the same bearing top and bottom. Beats 39.95 + tax per hub assembly from the dealer. Quote
grey beard Posted March 19, 2007 Report Posted March 19, 2007 My understanding of the inner seal is that it is designed purely to keep differential grease from getting into the bearing, which is the way most other kinds of rear axles lube their rear axle bearings. If the inner seal leaked, no one would ever know it unless grease passed beyond the outer seal and conaminated the brakes. JMHO:) Quote
blueskies Posted March 19, 2007 Report Posted March 19, 2007 Right rear, P15. Interesting to note the differences between your P15 and my P20 rear seals... The outer seal on the later model seals to the axle, not the drum. I bought a couple of replacement seals at my local NAPA auto parts, they can cross reference the numbers if you have them.

BobT-47P15 Posted March 19, 2007 Author Report Posted March 19, 2007 Actually Pete, my rear end is from something like a '39 Dodge pickup....is older than the rest of the car. I think a correct P15 seal looks like yours. My car was wrecked on the right side, probably back in the 1960s sometime, and judging by some big scratches on the frame, the rear end was likely damaged. It was apparently replaced with what they found handy at a salvage yard....that would fit. I didn't know that for a long time.....only lately when I listed the numbers from the pumpkin and someone looked to see what they went to. The brake cylinder is larger than a P15.....these babys are about $50 each nowadays. Quote
Merle Coggins Posted March 19, 2007 Report Posted March 19, 2007 My '50 truck axle also seals on the axle shaft like what Pete's shows. I too was able to get inner and outer seals from Napa. There was one that they didn't have in their books. I think it may have been the front seals, but they were able to cross the number from the original seal for a match. As for the puller, I used a 3 jaw slide hammer puller to get my inner seals out. It crushed the seals, but it worked. Merle Quote
Reg Evans Posted March 19, 2007 Report Posted March 19, 2007 The outer seals I just got from an eBay sale for my 40 were listed as only fitting 36-42 mopars. part # 891437. I took my old ones into NAPA and they searched all their books and couldn't find them. The gave me a phone number for a bearing and seal company and those guys couldn't fend them either. I just checked to see if the eBay seller had any more listed and he doesn't. Darn. Quote
BobT-47P15 Posted March 19, 2007 Author Report Posted March 19, 2007 On my lunch hour today I went to two bearings supply houses here, but they were of no help....only deal in industrial, not automotive. One sent me to a truck parts store. They had a small box full of old National seals probably from the 40s, but none matched. Then one fellow called one of their wholesalers, who said they had two of the needed style available at a cost of $32 each. National part no. 5797. So, I am going to call some places listed in Hemmings Motor News before I decide whether to purchase those. Quote
Plymouthy Adams Posted March 20, 2007 Report Posted March 20, 2007 Bob, were you by chance dealing with bearings and drive? Most industrial place have minimum order...their usual 5.00 bearing is at least 25-30 dollars...I used to get good service there years ago but keep in mind my friend was employed there...last time I was in there I just walked out very light in the wallet but as it was the only place to get this bearing and my trailer was locked up along the interstate..did not have much choice..and that locked me up tighter than the bearing was...they ripped me to the tune of 23.00 for a outer bearing and race..well I got the trailer and my tractor home...you can get these on the average for about 24.00 for the entire axle... Quote
BobT-47P15 Posted March 20, 2007 Author Report Posted March 20, 2007 Tim....I went to Bearing Headquarters and IBT bearings. They might have an actual bearing if I had a sample, but no grease seals. Quote
