Replace both sides or just the broken one ??

I would suggest both if the cause is unknown

[Rods2]

During those 42,000 miles, have you replaced a wheel bearing on that side?

[omegod]

Hi, I won't be able to remove the shafts until tomorrow as i'm being dragged to Alton Towers today with little Omegod, will PM you later

[Kevin Wood]

I would replace all of the bolts. They are stretch bolts, and they may have come loose due to losing their "yield". Also worth cleaning it all up and using a bit of threadlock on the bolts.

I doubt the CV joints will have been damaged. Might be worth cleaning them up and re-packing with grease on final assembly though.

Right .. latest update .. and thanks for all the support and help so far ... Reconnected drive shaft best as I could, 2 bolts sitting proud, levelled both sides by jacking under bottom shock mount .... ran it..... no noises from gearbox or diff but the right hand CV joint was making sorry sounds and kept "snatching".

Next task to remove right hand drive shaft .. took nearly three hours as the damage done to the "dome" ensured it would not slide past the hub mounting face. Nearly resorted to removing the shock absorber and rear tie rod but had a eureka moment that worked and with a bit of fiddling and brute force off it came.

6 bolts, 2 of which are no longer true, and 3 plates, which show some signs of wear but nothing excessive



Damaged drive shaft ........ 





Poor picture of hub from the rear .. no sign of any damage to my untrained eye...



Removed the other drive shaft as I was already filthy and the car was in the air ... 10 minutes in total !!!!!!!!!!!



I decided to use a torque wrench to undo the bolts on this side just for interest, 2 of the 6 were MUCH looser than the other 4 ....

Plan * (whatever we have reached) ...  order two complete drive shafts from Omegod, who is having a nice day out at Alton Towers, and visit VX to try and get 12 bolts and 6 plates, just hoping that no damage has been done to the diff or gearbox. I have not run it with the drive shafts removed as I suspect all I would do is throw diff oil everywhere !

What oil do I need for the diff ?? I'm tempted to suck as much of the old oil out via the drive shaft holes and replace once all refitted

[amba]

For the small extra bit of work and total peace of mind with the diff might be worth while removing the face plate as that will ensure all the old oil is fully drained.Will give you the oppurtunity of looking at the crown wheel to ensure no broken teeth or fragments of metal inside.

Just give it a thorough clean and reseal the plate with loctite sealant or a similar silicone seal,then refill diff with Hypoid 90.

i suspect that if you take off the driveshaft cv joint  cover and beat out the damage with a hammer,the horrible noises you mention will disappear. ps why are you changing the other driveshaft?

[amba]

Should take about a ltr to be at correct level which needs to be check with car level and diff oil up to temperature..as with autobox...fill it till it starts to drip out

Hello Stranger .. long time no see, called by your premises a few times but never anyone in !! Hope you are keeping well. I keep regaling the forum about your ability to change a rear wheel bearing in less than an hour !!! and your "special" extractor tool !! - shame I never took photos....

With the damaged cover plate removed (it fell off all on its own) manually rotating the CV joint in various directions it does not feel as smooth as the undamaged one, certainly has some rough/higher resistance spots, so I think it is FUBAR

Changing both simply as a precaution and to have both the same "age" for want of a better word.

Thanks Amba .. will do as you advise 

[Marks DTM Calib]

just fit a single new drive shaft, nothing wrong with the other one.

[tigers_gonads]

Oh 'dangle berries' 

You should be able to move the box on with no problem if you need too.
Give us a shout if you go down that route and need the boxes history verifying mate 

[Shackeng]

Pry bar/large flat screwdriver between diff case and drive shaft. Simply pops out

There is/was a gm repair kit...

I do wonder if all that mess is a result of complete joint failure... not sure if those bolts were actually tight enough

Nige torqued them all to correct setting in mine & Chris`s (Shackeng) presence, then double-checked.

Can't equate this with the careful way this work was done
