How to make use of, modify, and modernize 1974-1975 IH 200 Truck 4 x 4 axles, Front Dana 44hd, Rear Dana 60 FF.
Also known on Napa's website as:RA10, RA11 (4,500 lb. IHC) Axles w/ RA16, RA17 (Spicer/Dana 60) Axles Except Dual Rear Wheels w/ Dual Rear Wheels.
NAPA's website was very helpful in cross referencing things.
This thread is about full floating, single wheel rear Dana 60's, not semifloating 60-2's and such.
Also about Dana 44hd front. Convert to common chevy stuff, too.
These axles are a pain in the a$$. However, I have them installed and bolted in, geared, locked up, 4 wheel disced and chevyized so that on Sunday night I can go to the local discount auto parts store and normally pick up anything I need...except rear axle bearings.
This thread is meant to be a reference for those other suckers who are trying to make these odd ball axles work.
Its a work in progress, so bear with me.
Rear inner and outer bearings and races (cups) and seal from NAPA, SKF bearings from Japan:
You need this type silver/gray square wrench to remove your lock nuts:
Its a 2 1/2 inch size. One inch drive. OTC part number 1921.
This is one of the two locknuts:
Locknut washer available from IH/Navistar Triple Diamond Trucks dealer. Part Number 65678R1
NUT LOCK RET. Six States has them too. http://www.sixstates.com/products/partdetails.jsp?part=65678R1&supplier=IH
This is the hub stripped:
Setup of a spaced AA Mfg bracket to use 1978 Chevy single piston 3/4 ton 4x4 calipers, rotors, and pads:
Replace the smaller rear studs to 9/16 chevy studs. Part Number _____ Press/pound these into the 1978 Chevy 3/4 ton rotors/IH hub. This stud is long enough to engage the hub through the rotor.
Wheel nuts for the Chevy studs:
More to come.
