Help identifying my axle please
My jailbar truck has a different rear axle fitted,
Hoping to establish what car/truck it is from. Hopefully I might be able to change gearing later if necessary. Whether I can find parts in the uk is another thing!! |

Re: Help identifying my axle please
Looks like a Dana 44, used in later Ford pickups ('49-'56 I think), '49-'51 Merc, early Jeeps, and a host of others.

Re: Help identifying my axle please
If it has early Ford 5X5 1/2 pattern (and is not redrilled!) I think that would reduce the pool of candidates to F1 pickup and '49-51 mercury...I think!

Re: Help identifying my axle please
How easy to change gearing on these?

Re: Help identifying my axle please
Gear changing is all about the same on the later open rear ends. It is not easy unless you know what your doing. You normally have to set the pinion depth, backlash, check the gear pattern, that sort of thing.

Another thing about D-44's... they almost always have '44' cast on them, somewhere. Take a good look, especially at the 'front' view, scrape off any gunk, and look for a '44' (or a '41', or ?). It's usually plenty big enough to see. About changing gears, about like JSeery posted. I've spent a good deal of my 'mechanical-life' doing D-44's (& other Dana's), so I'd say 'easy'. But, if you haven't done one before, it might be at least intimidating, if not impossible. We could talk you through it, here. (To add to what Bruce posted... other possibilities include some Jeep models, and Scouts, both have 5-5.5. Look at axle ends, are they flanged, or tapered with hubs, like pre-48 Ford?) After looking more closely at the bolt pattern on your diff, vs a D-44 diff, I'd conclude that you do NOT have a D-44. I think if you look closely at the D-41 cover, you might agree that yours is a D-41 ??? (Last I was aware, some of the D-41 parts are nearly impossible to find, unless you consider used.)

Re: Help identifying my axle please
Check on the HAMB. I think the rear axle gurus over there have mentioned 2 generations...a proto-44 including the 1949 Merc and F1, and a late one as used on many medium applications more recently. There is PARTIAL interchangeability. Those guys may be able to tell you what's what...

Dana 41 for 48/49 F1 & 49 Merc. They have a smaller diameter carrier than the 44 and are hard to source parts for.

Re: Help identifying my axle please
It is definitely a Dana 41. As fitted to some early F1's.
Also fitted to some 49-50 Merc's. The Merc has the spring pads originally fitted to the bottom of the axle casing. Parts are hard to find, especially the crown and pinion. Tip, the Dana 41 rear ends I've player with usually have at least one broken crown wheel to diff carrier bolt. Often times not that obvious, they seem to (luckily) stay in place. Bend back the locking tan washers and give the bolts a turn to verify all's well. Easy access after pulling the cover on the back. A's for ratios, 3.92:1 or 4.27:1 most common, I think their was a 3.lower number fitted to Merc-o-matic cars. Martin. |

Re: Help identifying my axle please
The Spicer Dana 41 pre-dates the Merc-O-Matic. On the Mercs they were limited to the ratios Scooder mentioned like the early 8M 3.91:1, 4.27:1, 4.55, and the 0M 3.92:1. They only have a 5 5/8" carrier where the later Dana 44 had a 6 5/8 carrier. The axles, side gears, & bearings all interchange but the case, R & P gears, & differential carrier do not.

Re: Help identifying my axle please
There's some evidence of some old bracketry "expertly" removed from under the axle.
The casing has cleaned up quite nicely,still attached to the truck,don't want to disturb the brakes. Presumably the original axle broke decades ago and this was fitted. I was hoping parts would be easier to find for this one! Hoped to be able to achieve a sensible cruising speed Ian |

Re: Help identifying my axle please
They 41's your kinda stuck as far as smaller number ratios go.
The plus side to this axle over the stock for your truck is the fact you can plop the brake drums off easy, no special tools. Brakes are bendix pattern, much cheaper wheel cylinders, getable almost any place. And safe axles, if you break a half shaft the wheel doesn't bugger off into a ditch. Martin. |

Dana 41. When I rebuilt mine Randy's Ring and Pinion had every part I needed. Excellent prices and shipping. Some of the Jeep suppliers also had parts.
