Well I may have been wrong over the dually 60. I did some weed cuttin to measure the two 60HD's I have in the yard. One from a single wheel 91 d250. The other from my 85 crew cab d350 dually. Both measure spring pad to backing plate the same
. Didn't do a side to side measurement though. I would guess the same
. Soooo, maybe someone put dually hubs on this single wheel D60HD. It's got me confused. I need to find a part number or build number on the axle tube to get to the bottom of it.
What is the difference between a D60 and a D60HD? I was told the inner wheel bearings are different in a D70 vs a D60.. Well they were the same in my situation because I swapped the hub, bearings, seal, brakes etc. Maybe the HD makes it have 70 hubs/parts?
I was gonna scrap these two 60's I have, but now I'm keeping them considering they have some parts I can use in my 70's. Heck even the spindle locking nut which is about $16 at NAPA, hell I'll steal those out of them.. Actually I think I have already in both LOL.
