I have an 87 Ford F-250 with a 6.9 Diesel and am trying to figure out what axle it has in the rear. I am looking for a dana 60 to put in my mud truck and this axle looks about like a dana 60 although it is not a full-floating axle. Any ideas or comments would be appreciated. Thanks, Matt
The 87 250 should be a 10.25 Sterling. The 350s used and might still use the Dana, but I am pretty sure that the 10.25 went in around 1980ish. Someone around here has a guide to identifying Ford axles, but I do not remomber who.
Thanks alot for the info. I had a feeling it might be a sterling axle but i also thought that the sterling axles were full-floating but axles are new to me and i haven't had to deal with them much, don't know much about them. Thats why i'm asking. Thanks, Matt
Something's out of whack. You could only get a semi-floating rear axle if you got a light duty F-250, but a diesel truck was always heavy duty. So either the engine is not original, or the rear axle isn't. I am not aware of a semi-float Dana 60 that was common enough that you might stumble across one, although you may have a rare axle.
More likely than not, it's a sterling 10.25" axle that a previous owner swapped in to replace a broken rear end.
If there is no fill plug in the rear cover, that will confirm it's a sterling axle. A fill plug in the rear cover means it's a Dana axle.
