In the words of Emily Littela, "If it's not one thing, it's another". I think the rear axle in my 55 Merc has breathed it's last. Yesterday it suddenly developed a lot of play and a loud bang on releasing the clutch. I got the car up on jack stands and can now rotate the driveshaft about 3/4" back and forth before feeling any resistance. I have never abused it, but who knows what's in its past.  So my questions: Are internal parts still available for these Spicer/Dana 44 axles? Anybody here swapped a later axle into a 55/56 Merc? I'm thinking a 9" or an 8.8" would do the trick, but which donor vehicles have an axle of similar width? I'd like to keep the original lug bolt pattern if possible. Any help appreciated.

The early Ford 9" from a 57-58 Ford full size passenger car would be a good swap for your 55 I think. The 57 Ford 9" has an overall width of approximately 57" from axle flange to axle flange and approximately 51" to the inside of the backing plates. Take measurements from your rear and see what they are. They have the correct lug spacing (5x4.5") and use the big drum brakes (11"x2&1/4"). You may need to relocate the spring perches. These early Ford 9" rears are getting hard to find, but I just found one that was under a home made utility trailer complete with the pumpkin and 3.56 gears. Rono

You'll find the 65 t0 66 Mustangs had an 8" that may work. they were pretty narrow vehicles. The Later Rangers used the 8.8's and the Explorers did also, some of the Explorers came with disc brakes. 67 up Mustangs an Fairlanes came with a narrow 9'' but I think they all would need spring perch relocation. That's not a big deal. summit and jegs both sell the perches.

I parted out a 55 and a 56 that had good rear ends I disassembled one of them before i decided to do a 9 inch.. They are pretty beefy. Slightly more so than a Dana 44 They have 30 spline axles, and I think mine had a 3:18 gear.. If you want i can probably track one down for you

Guys, Dobie said he would like to retain the original bolt pattern for the wheels. If I remember correctly, the '55-'56 Merc had a different bolt pattern than Ford. Most of the 8" and 9" suggestions will have the Ford pattern. Pickups probably have the larger pattern. My suggestion, Dobie, is to pull the back cover and see what the problem is. Then check with RB for any parts needed. I have seen the spider gear pin come out partway and contact the pinion gear with a bang.

I have also had a pin come out part way and heard a big bang when it hit the ring gear, the keeper pins were known to shear off and then the spider pin slide out. I just pushed it back in and welded each end of the pin so it wouldnt slide out again, no more problems after that.

I have a complete one out of a 1955 bird that has 4:30 gears in it right now but I have a set of 2:95 gears for one too and some extra parts if you know what you need. I am in northern Illinois.

That would make repairing the 44 a better bet eh?
