14FF casting age

[sandawgk5]

Does anyone know how to tell the year of a 14FF? Is there a casting date on the housing or something? Mine has some numbers and a casting clock like engine blocks have but I am not sure how to read it. I checked billavistas 14 bolt bible and it had no data on the subject.

Thanks

check the numbers on the ring gear. then post up what they are.

that won't tell him the year of the axle, just the year of the ring gears....

Any posting of numbers will have to wait until I get home from work but I will post the castings off of the housing and there locations when I get home in case anyone might know anything. It would be so much easier if they had a BOM on them.

axle codes ..

They stamp axle codes on the axle tubes--the dealer parts book has them listed,tells the ratio and year,and whether its a posi or not..They are usually not stamped where they tell you too look though...they say its on the passenger side axle tube on the upper surface near the pumpkin,but I've found them on the drivers side,on the bottom of the tubes,etc--and they are not stamped very deep many times...every axle code I found required me to wire brush nearly the whole axle before I finally spotted them..your dealer can look up the codes--its a 3 letter code like RAH on older 73-87 trucks.....

Thanks I will try to see if I can find that on mine I have had it stripped down wirewheeled the hell out of it and primed and painted but I did not see anything. Of course I was not looking either.

Thanks again

I found the stamping on my axle and it is RFJ. Can anyone tell me what this means I know it is a 3/4 ton based on spring perch width but I do not know what year. Any help would be great thanks.
