14 Bolt Full Floater
« on: March 10, 2010, 03:56:08 PM »
So I've been looking for a 14 bolt rear axle for my 1988 K5 Blazer 4x4.  I finally found one on craigslist, a 1970 semi-floating 14 bolt from a pickup.  My k5 currently has a stock 10 bolt.  How hard is it to swap these two axles?  Are all the brackets in the same place or will I have to do some major fab work to get that 14 bolt under the truck?  Thanks for any help.

If it is under a 70, I would measure it first.  Does it appear that the perches were moved.

  Keep in mind that there are 2 different spring perch widths on the 14 bolt when you are talking 73-87 chevys. 1 is for the 3/4 ton and the other is for the 1 ton.
  I sold a guy a 14 bolt from an 83 1 ton and he claimed that it had the correct perches for his 71 3/4 ton.
  If he was right in theory that 70 you are looking at may have a 1 ton 73-87 14 bolt in it. If thats the case you would need 1 ton spring perches to make it work in your blazer.
  A 14 bolt from a 73-87 3/4 ton is what you want. It will have the perches in the right spot.
 I hope this all makes sense.

I havent actually seen the axle yet so I don't know if the perches have been moved.  I plan on going to look at the axle this week so I'll measure my 10 bolt perches and see if the 14 bolt is the same.  

How hard would it be to move the spring perches?  would the shock mounts also have to be moved?

You should try to find a full floater. Much better axle.

Would a semi floater even be under a 1 ton?

If its a semi floater its not original to a 1970. Its 81 / 82 ish or newer. Agreed I would wait for a full floater.

well the reason I like the semi floaters is because their 6 lug.  But the craigslist ad says its 8 lug so I don't think the guy knows what he has.

The 14 bolt 6 lug semi floater is from the 88+ (newer style) trucks.
A 14 bolt FF from a 73-87 3/4 ton should be easy to find for $100 or so on craigslist.

Yeah, I think I'll just keep searching for a FF.  Can you buy front 10 bolt axle shaft that are 8 lug?

They did make a 10 bolt with 8 lug hubs but it will be a little tough to find.  FYI Dana 44 outers will bolt right on to the 10 bolt axle, "Knuckle, Backing Plate, Spindle and 8 lug Hub Assm."  Everything will bolt right on... You can even use your existing brake calipers.   All will interchange.. Chvrolet, Ford, Dodge and Jeep.    Check out this website.
