Been checking 39 Ford rear brakes and somehow managed to misplace an axle nut. Have not found it so decided to fit a replacement.
The replacement ones in the spares I have are a shorter length than originals which are 3/4" whereas these new ones are !/2" which will screw up the alignment of the cotter pin once torqued!! Will be fitted a longer 3/4" one.
Also these fibre washers as supplied in the kit are to fit into the wheel hub behind the steel washer. What is the point of these fibre washers?

Thanks Phil NZ

I think that Ford repurposed the P/N 351152-S nut to retain the steering arm on F100 pickups so they changed it for clearance. Why they just didn't spec a new nut, I don't know. The fiber washer was listed as a gasket in the old parts drawings.

There is a guy that makes them from 1018 steel and sells them on flea-pay but I don't know if they are as tough as the OEM axle nuts were. Original is usually better but they are getting harder to find. These have the full hex and the full length from top to bottom 3/4" and 1 1/4" hex size.

Some where in there, Ford changed to the P/N 356074-S nut that doesn't have the nut hex all the way out to the end of the castellations. Mac VP sells a replacement for those with P/N 34034-S. but that's about all that's available.

Roy Nacewicz has his own nut kit H-001 for the axles. These are likely like the 356074-S types but I don't know for sure.

Got a picture?. I don't relate to specs but I can read a picture.

Sure but I need a email

Thanks very much for all information as advised. No realnee to worry about the fibre washer and will be using an original nut with the 3/4" length.

Ithink the fibre washer is to keep dirt and grime out. You can make one out of a piece of a leather belt also.

The fiber or leather washer is there to keep the gear lube in.

If Fred has them, you are good to go. (Barnfind08)

How about this then. Had the rear up on axle stands while doing the rear brakes.
Thought I'd check out the diff in operation for noise etc whil up on stands.
Started up engine and into 1st then 2nd gear. The LH side was turning at a constant speed. RH side slower and hesitant.
This is common if both rear wheels off the ground due to diff drive action.
AmI correct with this assumption.
Thanks Phil NZ

That is correct. Differential design allows one wheel to stop turning while other side doesn't or keeps on pulling.

Phil Gillespie · 02-26-2018, 01:02 AM

I thought that was the correct thinking but it still prompted me to recheck my brake shoes again.
The differential design does it favour onne side always as the non turning side?
Also on the plus side found my "missing axle nut" so all parts nnow accounted for and all tools back on racks where they belong.
Thanks

The intermittent favouring of one side is not a result of a problem in the diff. It probably shows a slightly heavier brake drag load on the slower side. It is probably not a significant issue, and is typical.

I say probably because I cannot rule out that your brakes may need some attention, but I think you may have already covered that.

Hi Mart, Yes thanks for that the RH side does have a little more drag than LH side . Intend to recheck after a few settling in miles on car again along with axle nut torque. Jus always keen to understand the reasons etc for such things.
many thanks,
