Rear Drive Shaft Problem
My Second posting today on this topic, and I understand my issue better now.
Whilst building up my back axil today I discovered that both my drive shafts (Sierra) have Right hand threads for the hub nuts - apparently the older
version with drums had this arrangement, they used to be 'staked' into an indent into the shaft.
I have converted drums to disks and this leaves longer threads so the staking ring is no where near the indent when tightened up as the nut screws on
further and past the indent.
So the question is do I use two Nylock style nuts with RH threads on both sides or get
another passenger side (short one) push in drive shaft with left hand thread and replace it?
Does anyone have a usable one surplus to requirements?

Cant you get a large washer/spacer turned up to take up the difference?

I need some original type nuts too with the staking ring - forgot to mention.
But yes I could use a few drive shaft washers to pack out

Can you use two castellated nuts and drill the stub axle for a split pin?

Think I'll use two new RH nuts and put a pin through the passenger side shaft.
Thanks for the help guys

My old drum style rear axle has both left and right hand threads. It may well be after they changed the style though.
I assume you have indeed got a pair of shafts and that one is longer than the other?

Hi David,
Yes, they are on the car, just noticed now when fitting the bearing carriers - just worried about the passenger one loosening up in use.
Apparently the very early cars had this arrangement

I would add a positive locking device (pin lock wire ect). As they had one before..
As to nyloc might be o.k ford did not think so until they had left and right handed threads (i.e. the nut then tends to tighten not loosen on both
sides)... Bit to mission critical, I'd want a positive locking device if they don't have left and right handed threads.
