Lol my bad, its an 89 with a 350

89 should be 10 bolt rear and ifs in front.

 

[bluejeepkid]

Hmm, I may have the year wrong because it certainly is not ifs. I suppose its probably a little older then 89, its a leaf sprung solid axle.

Probably a ten bolt fore and aft. Google up some pics to find out for sure.

if its not ifs. its a 10 bolt front

 

[bluejeepkid]

73-91 has the solid front ends. if its a half ton it will be a 10 bolt front and back. the 3/4 burban 4x4 comes with a 14sf rear axle and massive 56" springs. the 3/4 ton 2x4 will have the 14FF rear axle.

hurm. i thought the half ton burbans had the same running gear/suspension as the half ton pickups.

my mistake

blazers $ suburbans were the same and the half ton pickups were different
bluejeepkid you probabley have a 10bolt front with a 12bolt rear.

 

[bluejeepkid]

12 bolt rear? Even tho its 6 lug?

yes.

If it is an 89 it has 10 bolts front and rear.

The blazers, suburbans and 1 ton trucks had solid front axles up to 91. They stopped putting 12 bolts in the rear somewhere around 81 or 82.

Isn't what your calling a 12 bolt a semi-floating 14 bolt? I have the axles out of an 86 3/4 ton it had a 10 bolt front and sf 14 bolt rear.

Blazers/Tahoes/Suburbans lag behind the trucks by a couple years. Trucks remodeled in 88, SUVs in 91, again for the trucks in 98 or 99, SUVs in 2000ish.

 

[bluejeepkid]

Ok so.... 10 bolt front, 10 bolt rear? To clarify, its a half ton suburban, not a 3/4 ton. Reason I'm trying to find out is i wanna look up gears and lockers for a friend.

Yes 10 bolt front and rear. Before my xj. I was a Chevy guy amd ran w the chevy full size crowd and owned a 3/4 ton suburban that I turned into a 1tons crawler on 39's.

 

[JC93XJ]

I would not waste my time w that 10 bolt rear. It will not survive under a full size doing any offloading or towing.

A 14ff can be had for a $100 or less at jy and convert the front to 8 lugs.

it could also be a sf14 bolt in a 6 lug as well. Thats whats under my mj.
