I've got a '86 F250 SuperCab 4x4 that I believe to have a Dana 50 IFS on the front, however I don't have any solid evidence on that, so it may be a Dana 44-HD IFS. Is there any way to tell by looking (other than the factory tag, which is so rusted it can't be deciphered)?
Anyway, I removed the hub but now can't get the locknut off. I purchased a special tool (OTC No. 7158) that is supposed to be the equivalent of the spanner wrench D85T-1197-A that is called for in the repair manual. The tool fits on the locknut just fine, but I can't get it to budge. I thought the torque specs were about 35 ft. lbs. on the locknut so it shouldn't be on too tight, right? I put a 1/2" drive breaker bar on the tool, then put a 4 foot pipe on the breaker bar, and I still can't get the locknut to budge.
Have I got the wrong special tool? Am I going about this the wrong way? What am I doing wrong?
I'm half tempted to purchase the special tool for the Dana 44-HD IFS and see if that works, however the special tool I have fits just fine and I was under the assumption that the SuperCab models were equipped with the Dana 50 IFS. Any suggestions would be appreciated. Thanks.
