Rockhauler Posted April 15 Share Posted April 15 A few years back I grabbed some 4x4 parts from a local wrecking yard that was sending some older trucks (80's to early 90's) to the crusher. So today looking through some of the parts found this front diff, haven't found a Ford logo or part number yet but Dana is stamped on the ring gear. I assume that's clutch packs tucked back in behind the spider gears. I do some traveling on old logging roads but no extreme 4x4 stuff would I be better off with a open diff and pass this onto someone who could really put this to use.

ArdWrknTrk Posted April 16 Share Posted April 16 That's an interesting piece, with bolt on axle tubes. Does it have any casting marks indicating exactly what it is? Can you decode the BOM? Link to comment Share on other sites More sharing options...
salans7 Posted April 16 Share Posted April 16 That's an interesting piece, with bolt on axle tubes. Does it have any casting marks indicating exactly what it is? Can you decode the BOM? Jim, those holes by the opening for the axles are for the support that comes off of the diff housing as shown below on a D50 halve. The only trucks to have a bolt in-axle shaft were the 1980-1983? D44's (maybe D44HD and D50 too but not sure). Link to comment Share on other sites More sharing options...

85pig Posted April 16 Share Posted April 16 One of the TTB diffs - can't tell which one off hand. Does appear to have 3.54 gears in it. Link to comment Share on other sites More sharing options...

Rockhauler Posted April 16 Author Share Posted April 16 If it was a 50, it would have a big "50" cast in it... Sorry guys should stated in the first post that it was from a F150 just not sure what year. The trucks I was grabbing parts from were in the 80-89 years. Only casting marks I can see are on the bottom if mounted in the truck shown in the first picture, second picture shows the other side of the diff.

D50's only came on bigger trucks,350's until '85 and 250 extended cabs (only) for sure. Crew cab 250's and regular cabs got the D44 HD unless optioned with a plow package, or intentionally ordered with the big hub D50 as a stand-alone option. But you will see "50"cast in to the diff case. Link to comment Share on other sites More sharing options...

Not sure what year that changed. Maybe around '84??? Link to comment Share on other sites More sharing options...
