Hi all,

 

While playing with this car in the shed, we noticed one of the rear driveshaft boots had a small nick in it, so we thought we'd replace it. 

 

Dissasembled and removed the passenger side shaft, easy as.

 

Goes like this - 

 

Wheel off

Disc off

Disconnect handbrake cable

Disconnect brake/ABS sensor

Unbolt the entire wheel hub assembly from the suspension arms.( no need to touch the big 25mm- ish lock nut in the outside centre of the hub, as all it does is keep the wheel hub/bearing/ wheel hub CV type joint all in one piece)

Give it a good hard yank/tap off, and the whole hub slides off the outer shaft on the driveshaft.

Grab the outside end of the now exposed drive shaft , while someone else gently prises the inner end of the shaft out of the diff.

Done, all good.

So it is clear that the thing that holds the ends of the shaft into the diff at one end, and wheel hub at the other end...is the compressible circlip on the spline at each end of the shaft.

 

Goes to get the new CV boots and clamps and circlips, and old mate at Holden says ""you also need the big 25mm ish nut, as you should replace it"".

I ask why, and he says its a ""one use"" thing, and as you took it off , a new one is required.

I said I didnt have to touch it to get the shaft out."" No""  he says, impossible, as it holds the shaft in.

I gave him the VIN of the car, and he still said I needed the big lock nuts??

 

WTF??

 

So I bough the workshop book ( Aftermarket) and downloaded the GM Pontiac G8 ( closest I could find) manual off the web....both show the big nut does indeed screw onto the end of the driveshaft. Just like he said.

 

Our driveshaft is aftermarket, hi po type..it doesnt have the thread on the end of the spline...I can live with that, as they have been on the car of a few years and work fine. See the  pic - only showing the big nut area, DIDNT touch it to disassemble. 

 

However, this means that our wheel hubs are different to the Holden ones?, the GM doc ones?, the tightarse workshop manual ones?

 

Why would this be the case?..surely HSV didnt go to that sort of trouble...and if so, why? Or was it just a factory variation for some reason?

 

Probably a dumb question.   

 

 

 

Thanks

Don't forget that this forum runs on carby's and points ignition Col.

Is the diff even the same unit in HSVs? The SS is 304 Kw compared to 430 Kw in the GTS. 

I know it doesn't really apply here, but the driveshafts in my Polaris buggy are only held in with the compressible circlip as well.

p.s. just notice it says 200..should say 2017!.
Thanks Laurie..it went back together with new genuine GM boots,clips,clamps etc. Just seems strange it is different to doco.

Can pull it apart any way you want, what ever is easier for you.
There was a change over of driveshafts and suspension bits between ve and vf.
I was told that possibly ve hsv had some vf parts in them.
Also the hsv gts's with the LSA engine had a different diff and driveshaft setup to support more power.
