A Rotten Day: The Curse Comes Home to Roost

My 1966 8" rear axle developed a leak, and it appeared to be the pinion seal. I've never worked on a rear end before (get your mind out of the gutters, will ya???) and I heard horror stories about pre-load and gear whine. I read up on everything, and get a seal from a local parts store, and asked AZPete to come over and help out. We marked everything very carefully, and took it apart. Found no washer under the pinion bolt nor a dust cover. We decided not to add those items, as we did not have the tools to check pre-load, instead going by marks on the nut and pinion to get everything back in place. Got the seal out and compared it to the one I purchased: they didn't match...not even close. So...off to the parts store and get it replaced. I bought some more 80W90, cause the rear oil was getting pretty black after 10k miles or so. Sucked out the oil, checked the vent to make sure it wasn't plugged, put the new seal in, and was ready to add oil.

I decided to check to see if I can just fill it up from the bottle, so I took the bottle tip into the hole, and it looked like all but an ounce or two would go in. I go back to the work bench to cut the tip off, and Pete says where's the cap? Cap? What cap? Oh crap...did it fall into the rear housing? We tried everything in our bag of tricks to see if the cap was there, but couldn't be sure. So...out comes the pumpkin. First, though, we had to pull the axles. I had never pulled the axles since I bought the car (1998), and Pete doesn't like the sound of them. Crap. We call around, and only Pep Boys would press new bearings on, but we would have to wait 2 hours. Screw that...

Out comes the pumpkin, and we tear the gasket. Lo and behold, there's the cap, just sitting as pretty as you please in the bottom of the housing. We then go to three different parts stores looking for rear axle seals, bearings, and the pumpkin gasket. No one had any of them in stock (but one store did that the pinion seal in stock...go figure!). We have a pretty good NAPA store in town, so I'll take the axles in and they can order all of the stuff in time by next weekend when we'll put everything back together.

Meanwhile, the wifey is screaming at me to fix a dryer that's making a racket. What the F do I know about dryers? Pete does, and we took it apart, finding a bushing for the drum that is worn. Wifey will be ordering that part shortly.

I hate it when a plan doesn't come together and you pull a real Doofus.
 
Diammn,
What a day you've had. Yes sounds like payback of the curse. I have always worried about dropping something like a small tool down into a motor or tranny. Thank you for experiencing it for us.
 
mid,
had the EXACT same thing happen when I changed out the pumpkin on pop's 38. he went to see if the gear oil would go in with the bottle & knocked the little red cap off inside. axles were a lot rougher a job though with the way the SVO rear disc setup attached. spent about two hours alone getting those bolted back up afterwards...

so let me get this straight Mid, you let Pete mess with your rear-end?
Yes, but he was good enough to wear gloves.
 
Ugh. Sorry to hear you had problems. That pumpkin is not easy to get back up in there. Seems to weigh about 150lbs when you go to put it back. Be careful with your back, don't need that messed up!
 
Shouldn't be that hard...we have a tranny jack that we used to take it out, although the muffler clamps were a bit in the way. By turning the clamps, we should have more room to work with.

It's nice to have the right tools for the right job. Now for the seal puller tool I bought some time ago, the shaft simply bent. We did figure out a good trick for removing the rear axle seals: I had a 6 foot 1" square tubing laying around. I had to take a phone call and Pete simply went in one side of the axle housing and popped the seal out from the inside on the opposite side...very slick indeed. Can't do this unless the pumpkin is out, though.
 
I've always used the 1" long pipe method of removing the axle seal. Yes, the chunk must be removed first.
 
Randy you don't need to really sweat preload, it's already done when the gears are set up. The only way you'll change it is if you over torque the pinion nut when you put it back together.

BTW, I feel your pain. I have a dryer to fix too...same damn problem!!!
 
That little loose bottle cap ended up costing me $162 in parts and labor on the rear axles... :soapboxrant
 
I know I'm a bad person for snickering, but I just can't help it.
 
Other than the axle bearings rattling when spun, axle seals being hard as rocks, we could have said to heck with it and not put new parts on the garage queen......could have even left the cap in the housing....won't move sitting in the garage. And......that cap just jumped right in that opening.....right.
 
So the truth comes out...Pete put it in the rear axle housing, simply to get me to do more work on the car!
 
Pete and I put the rear end back together; took it for a small drive (it was beginning to rain), no issues or drips. Now it will take some time to see if a rear end howl develops...

Pretty easy to put it all back together. The dryer is fixed as well. Pete was well paid with homemade dog cookies and a certain bottle of adult beverages...

When Pete was talking to me while you were driving, it sounded like the rear housing had a rattle to it.
 
Funny,this old timer back home used to "press" his own wheel bearings on without a press. He would cut the old bearings off and stick the axle in a bucket of ice. Then about 5 minutes before he was ready to put the bearing on,he would put the bearing on a hot plate. Working quick he would wipe down the axle to get the moisture off and then slide the bearing down,couple of taps with a block of wood and a hammer,it was on. Never tried it myself,but watched him do it a couple of times.
 
Yep....that hot and cold style works....did it several times when working on farms in Iowa.

The only howl so far was a certain owner complaining about a plastic cap being the cause of this.....even though the seals were dry and the bearings rattled on both axles. And the cap did nothing wrong....

Randy....are there still three caps on the shelf......
 
Right now, I see six caps, but I've also been draining/consuming a certain liquid...
