Let’s talk about the 14 bolt FF

[57taskforce]

I have a question I’m looking for some insight on. We all know how the 10.5” 14 bolts in the 1973 to about 1991 3/4 and 1 ton trucks, suburbans, vans etc all had inboard mounted drums (drum pinned to the back side of the hub via the wheel studs-have to remove whole hub, drum assembly to get to the brake components) in a couple different sizes. Somewhere in and around 1992 it seems that GM shortened the spindles a hair, changed the hubs up to match the spindles, and started running outboard(slip on drums)… on every thing except for as it seems 1992-98 3/4 8600 lb gvw pickups. 3/4 ton suburbans and 1 ton pickups all seem to have gotten the slip on drums, I’m not sure about the vans in my research at this point. What I’d like to know is do the 1992-1998 3/4 ton trucks still use the same old SRW hubs from 1973-1991? It would seem to me they would have too because from what I can tell the inboard drum setup still uses the old style spindle. I guess to ask the question another way, does the 88-98 trucks with inboard drum 14 bolt ff use a different single wheel hub than the sqaure body 14 bolt single wheel trucks or are they identical in every way? (Wheel placement etc.)

Reason I ask is because my 98 K2500 spun an outer race in the hub and Ive got an extra set of square body hubs I’m hoping i can rebuild and replace it with. I didn’t have the extra hubs with me when I had it apart so I couldn’t compare everything at that time. And I was in hurry to band aid the truck back together as it’s my current DD.
