This rear end project seems to bounce along the bottom.
I saw some ridges on the bearings on the old red neck locker.
Upon closer inspection, corrosion also. Then I cleaned up the welds.
7018 and oil don't mix. The welds have porosity, not saying it wouldn't work.
But I'm not going to test it out. I'm going to give it back, half of the welds need to be ground out, cleaned and redone.
A week ago today I ordered carrier bearings for the Eaton posi. With the long weekend, they didn't show up till Wed. Of course they were too small/ OD.
So thursday, I called the big name supplier and got tech. support. She found what I needed, 3.150
bearings and races. She asked if I wanted to exchange. I said no, that'd take a week or so, I want to run the car sunday.
I'll return these and order new. She says I'll send you to sales then. I stopped her and asked if they'd have the numbers on those bearings, just give me the number.
She said they have all that and switched me.
Another 10 minutes on hold and the guy couldn't find what she was looking at.
We went over and over the bearing sizes, his book only said 3 inch bearing.
I told him there isn't any 3 inch bearing, it's either 2.89 or 3.150.
I got Timken on the phone and got bearing and race numbers. 57 chev belair
Back to the first outfit
Not in stock, had to order from midwest.
Called local bearing supplier, and had them here at noon today, Friday.
I've been reading up on this swap, seems some guys have to do some grinding.
So I tried the unit with out the ring gear, sure enough no go.
Called Mike at west coast diff, he's been great, Oh you're not re placing a
LSD then yes you need to grind/machine that web to clear.
So I ground it out, and it runs true.
But I ran out of steam, tomorrow I'll put the ring gear on.
Set lash and reinstall. Hope to get test n tune sunday.
Been having trouble with the drivers door popping open.
Pulled the fender off the other day to adjust the hinges.
Did no good.
Looked at the end of the door and found a trim screw too long
to allow the latch to do a second click. UFDA
Today I took a road trip, hour and a half over the pass.
Those cherry bomb muffs are killing me, new turbos and dumps are here waiting to install.
Temp got to 190* at the top of the pass and dropped right away on the way down.
Thats with a 1964 4 blade fan and the stock 49 copper radiator.
I'm a believer in aluminum heads.
Anyway I went to see the guy I traded the SBC to for the 3.55's.
He's the most regular guy I've met in the last ten years.
Not only did he give me this redneck locker and two axles with good bearings, for the 57 rear end.
He showed me the rear I started with was 3.36 gears, UFDA, there ya go, I came up with 4.11's
Then taught me how to set the lash on these.
And What to watch for when rebuilding, seems like most folks just want in your pocket book.
He was trying to sell me a beefed up Ford 9 inch he'd narrowed- wouldn't fit between
So tomorrow an Eaton locker is showing up for the 3.36's and the redneck locker will go into the
3.55's for the strip.
Got to say sompin about that. First place I called, had to check fit for 17 spline axels.
Hour later calls back, has had one on the shelf for a while- $110 more than the others.
Quote- they're hard to come buy.
Second place $50 over price.
Third place----$238 over price- same ****- they're hard to come by.
BS- Eaton and Dana started making them again.
Did find a square shooter though.
One of my wiper arms popped off the other day, truck ran over it, new one from chev's of the 40s installed, didn't detect any leaks in the windows or trunk in that rain storm. crossed fingers.
So much for the bearing splitter.
After much sweat and profanity, I called around,
of three frame and axel shops, only one would tackle the 57 axel.
Shame on me, i got lazy, should have done it my self.
After reading up, I'm not going to be pounding on this axel with a sledge
to crack the bearing. I'd cut it with a grinder.
Turns out thats what the (experts ) do.
So I paid $50 extra for Napa to put a Chinese bearing in one of their blue boxes.
And a hundred to get it installed, UFDA! And the car sat on blocks for three days
what a knuckle head.
Did get a new fuel gauge installed, works great with the key on.
When the car runs, it goes up and down with the tac.-- Think I need a separate ground.
Got 1 1/2 vent window seals installed, read up on that too.
Not much help, most of the stuff is for crank vents. Did use some RTV
and plastic to plug a hole at the top-want to get it car wash ready.
Found some one had stuck a button in beside the tab that holds the vent lock shut, on the drivers side.
Reminded me of an old van I had, Had a nickel in there to keep the rain out.
If i finish digging the petrified rubber out of the channel, and finish the vent seal,
may get to the track for a testntune. Check out the new cam and 3:55 gears.
Going to try an race this weekend.
Bearings before and after--- there's a partial nylon seal on the new bearing, not sure what that does.
yes all the brake parts are new as are the wheel bearings.
But the one on the short axel is on backwards.
I've got a bearing splitter some where, I've never used
will have to dig that out. And a bearing press, which i haven't used for axel bearings yet.
But first the speedo gear swap.
with 4:11's and 26 inch tires I was .3 short of a mile
now with 3:55's and 29 inch tires I'm .3 over a mile marker.
Got a 19 tooth driven gear installed and a 21 tooth gear to install.
I was guessing driving with traffic about 65 mph
reading 80 mph--- three teeth supposedly 15 mph.
3:55's dropped it down to about 2400 rpm on the highway, cam comes on at 2000.
Good enough, the pipes aren't roaring now.
Old punkn out new punkn in.
In stead of putting the axels in, thought I'd square up the rear end.
I thought it was put in without drilling new holes in the pads.
But I plumb bobbed the axel on both sides and it's right on.
At least square with the frame rails. I do get the slightest wonder,
since the back is square, it's time for front end alignment.
Get the shop to do that, thats not something I need to learn.
Tomorrow I'll be on the freeway checking RPM and the speedo.
