Junk yard 14 blt ff $$$

[BlueOx]

I would like to add a 14 blt ff to my 85 blazer but I need some info. I have seen people on this board that show to have a 1 ton 14 blt and the others have 3/4 ton 14 blt; what's the differance? What do I need to look for when buying one. What kind will fit the Blazer with out any mods.
And last but not least what would one pay for one.

Thanks,
Charles

the one ton 14 bolts have narrower perches. you would have to remove and weld new ones on. i think that 1/2 and 3/4 ton are like 35 inches from the outside of the perches. measure yours before you go looking then measure the 14 bolt in question.

when buying one look for any obvious damage to the outside and inside. if you plan on regearing it from the get go dont worry about gears. a locker did come stock with them, both in the detroit form and gov lock. dont get gov lock. if you want to lock it later on you have to find an open carrier. also look at the gears to see if they are in good condition. i.e., no pitting, gouges, ab-normal wear patterns, or lots of rust. make sure the drain plug is not frozen in place, and also checkthe splines on the shafts.
some people think nothing of it but check for hammer marks on the inside of the dif cover. some folks tend to back into the strangest things sometimes....
hope i could help.

Any 3/4 ton 14ff will work. If you get a 2WD version you may need to modify the shock mounts because they are much lower than a 4WD version. Also a van 14ff will work also but the width is 3" wider. Some people like the extra width so the track is about the same as the front.

Thanks for the info

1 tons have bigger brakes.

3/4 ton 14ff come with both 11" and 13" brakes. The 1 tons all came with 13" brakes. I currently have an 85 suburban 2WD 14ff with 13" brakes in my blazer. Most 3/4 ton 14ff's I have seen have the 13" brakes on them.

The brakes on the 1-ton unit also come in 2 1/2 wide and 3 1/2 inch wide versions (depending on the year). Obviously I opted for the larger ones. For a full floating unit, junk yards usually sell them for $150-250.

You can get a nice FF down here in NM for about 100.00 if you do not want any wheels.
