Jason, FOT,
I think I can share the Moss report on the fix.
There are also potential design improvements.
I see great integrity in the way Moss USA dealt with this issue.
They are also being understandably cautious in its application.

> In short. The collar has been completely re-designed and impact pull out is
now better than stock. The tie rod design has also been improved to give a
wider range of motion.

solid mounts and sticky tires makes it inadvisable for us to give such a

> Code Line No. Date Comment
> 900 06/02/14 New number created for
re-designed Staco rack & pinion assembly. Collar of pinion housing crimped
> 901 06/02/14 onto the cross-tube on all
4 TR rack & pinion units 667-126, 667-126
> 902 06/02/14 Pinion nut also
redesigned: threaded section increased from 5.7mm to 12mm.
> 903 06/02/14 Pinion Nut Torque set at
factory between 15-25 kg-cm; nut secured w/anerobic thread lock.
> 904 06/02/14 In time, when it becomes
necessary to re-adjust the pinion nut, the nut is locked in place by
> 905 06/02/14 driving a piece of the
aluminium nut into one of the grooves in the collar of the pinion housing.
> 906 06/02/14 New tie rods droop a full
30 degree like the OE tie rods, while earlier they were limited to 26 deg.
> 907 07/02/14 Generally sold for TR4A
thru TR6. Can be used for TR4 from CT20064, which is when the rack
> 908 07/02/14 mounts went from
horizontal to vertical. That makes it possible to fit the later type rack.
> 909 07/02/14 TR4 tie rods are about
2/10 of an inch longer than TR4A- 6. Not enough to be a problem.
> 910 07/02/14 The tie rod ends are the
same for TR2-TR6; suggest 667-265, a pair of tie rod ends.
