Lets back track a bit. None of the parts catalogues show left and right, so thats out .Its got holden written in the writing so lets assume its peculiar to Australia, not a US axle. The 7437374 part 1st appears in the "HK Monaro GTS 327 " and it 1st appears in the " HK Monaro GTS 327 Supplementary Parts Catalogue". Catalogue # M36567. Parts listed in this catalogue were supposed to be 1st introduced with and peculiar to the 327 monaro, well that is what is printed inside on the 1st page but, may have become standard for later HKs. Part # 7437374 is also listed in the Yellow parts book but, Yes HK1837 it changed in the HK Blue parts book. After all this we still have'nt learnt what the writing, other than "HOLDEN" the writing means. Before we go any further with that has someone got the basic HK catalogues M35966 ( white cover with a yellow diagonal Holden stripe) and see what part # the salisburys were listed under and maybe also see if 7437374 appears in parts book # M36542, thats the "monaro" parts catalogue, also with a white cover with yellow stripe. These are catalogues before the blue and yellow, Thats all before the 81837 arrived. In other words what was the part # for salisburys used in HKs before the 327 was released ?. The 327 supplementary parts book seems to be suggesting the axles in the GTS 327 were up untill that time peculiar only to the GTS 327 Monaro. Sorry folks, now that would be an interesting development in this debate.....Jack

As far as I understand it there was no Salisbury (or Saginaw) prior to coupe release. Only banjo. This is reflected in M35966. |

Greetings, There is no LH or RH axle shaft and as such only one part is listed along with a quantity of 2. These axle shafts were cast at Holden in the same foundry as the banjo items. They first appear in M36567 because they were first used and are an integral part of that vehicle. A critical part of M36567 is wording IFC 'Certain items such as Salisbury Type Rear Axle Assemblies and Rear Axle Radius Rods "flow on" to other "HK" models'. The radius rods are not in M36567 but in the amendment bulletin to M36542. 90% of the amendment bulletin to M36567 relates to the Salisbury rear axle assemblies. It gets very confusing looking at parts information when you don't have it all. |

Back again, seems axles aint axles. Still have'nt found what all the numbers and letters are cast into the axles. Is there a possibility they are date cast numbers? and what of the two different part #s....Jack
Greetings, I think you will find that the reason for the different part numbers is because HT had a thicker wheel flange and longer wheel studs as part of the upgrade from HK to HT. The wheel bearings also changed at this time. The cast numbers/codes are for production batch identification purposes as the axle shafs for these imported rear ends were cast at Holden.
Very nice reasoning on why an axle should only ever turn in one direction by Squeak327.
Hi git. I am not quite as sure as you are about the increased flange thickness in HT/G Salisbury axles. Following is an extract from the HT Series Shop Manual Supplement P/N M36667.  Note it states the standard axle (ie banjo) has increased flange thickness, bearing capacity and longer studs BUT it deals with the salisbury in a separate para and only refers to the bearing. My question is, if all three changes were made to the axles of both types of diffs, why the need for two separate paras? In addition, I have limited annecdotal evidence that suggests that the salisbury axle flange thickness may not have changed from HK to the T & G - My HK is a clutch pack salisbury and I have a spare cone type out of an HT. All 4 axles have a flange thickness of a poofteenth under 9mm. This compares to a pair of HG banjo axles I have which definitely have a thicker flange at a tad over 10mm. Interesting! Perhaps one day when someone with a salisbury equipped T or G is working on their brakes they might measure the flanges in their car to add to the picture. A good number of years ago now, I went to Holden to buy a couple of replacement wheel studs for my car because their threads were a bit ordinary and was told that the HK stud was obsolete but the later T & G stud would fit. They were indeed longer than the originals so I ended up changing all 10 on the rear so all were the same length. For what its worth, my HK axles, like Jacks, also have Holden DH 3587 cast in them. The casting on the HT ones is too rough to be certain about. Edited by user Saturday, 26 February 2011 12:11:06 AM(UTC)

Greetings Squeak327, I use the Holden features books to base my information and learning on when I don't have access to a real world example. What you have posted from the HT shop manual is only part of the story. It is correct as far as the banjo axle shafts are concerned but has not told the full story on the Salisbury item. Not only do the HT Salisbury axle shafts feature thicker flanges and longer wheel studs, but the shaft diameter is also thicker. HK Salisbury and all banjo axle shafts are .94" in diameter. Salisbury axle shafts in HT and HG are 1" in diameter. As you appear to have both an HK and an HT axle shaft, get out the verniers and see what you find. All this is documented in the features book. I would imagine that the engineering specifications would also reflect these changes. |

Thanks for that git. I did not know about the thicker axle shafts, nor Holden features books. That makes me wonder whether the later HKs that went to the cone type LSD mechanism also had the thicker axles or not. It also raises the question as to whether a HT or G Salisbry axle can be installed in a HK diff - probably not unless they machined the splined end down to the HK size or you can use the corresponding HT/G side gear in a HK Diff. Next time I have reason to pull an axle out of the HK's diff I will measure the shafts. If I get a chance over the weekend I will pull the HT diff out of storage and check its axle diameter too.
I would be interested in acquiring a Holden features book at least for the HK. Any chance you can post a picture of the cover so I know what to be looking out for?
