Welcome

Hi everyone, I'm Chuck and this is my project. I am going to attempt to make this tired old truck into something worth driving again!

The biggest 4x2 truck around!

Ok, so I received the new hubs a couple weeks ago and quickly slapped them on and was excited to finally be driving a 4x4 again! To my disappointment though I discovered another problem, the front driveshaft was spinning but the wheels were not!

This could mean two things, differential problems or axle problems. UGH! that sucks. I'm 90% sure it's the driver side inner axle shaft that is broken but won't be certain until tear into the front axle. Why haven't I done that? I haven't started the front axle because I know the project will be a big one and will include a full brake job replacing bearings and seals and I just haven't had the dough to start it. I have been doing a ton of research though about the axle and decoding the tags to decipher what is inside.

This is what I found regarding the rear axle because it actually has a tag on it with the bill of materials and other info. The tag has this stamped on it:

4.10 D5TA LEB
603583 12 LS

I went to www.spicerparts.com to decode the tag and this is what I found. This website BTW was super helpful! I downloaded a maintenance booklet for the Trac Lok and The parts list and complete info for the rear axle. FOR FREE!!! Thanks Spicer! Also, spicer=dana=spicer interchangeable names one makes the other I can't remember which.

4.10= gear ratio: ring gear teeth/pinion gear teeth = 4.10 gears

603583 12 LS = B.O.M. Bill Of Materials, tells ya what is inside, and where it came from. This axle came from a 1975.5 Ford 3/4 ton HD 4x2 Full Float with limited slip aka Trac-Lok.
