Don't know what the limits are abroad, me personally would not tow at over 60 mph, but plenty do in this country have never towed abroad always fly if going overseas.

[Entwood]

Even more p*****d off now ....  

Back from holidays, tin tent parked up, so time to move the Omega onto the ramp so Daz can change the gearbox next weekend without getting his feet run over. Plan was to tow the car onto the ramp using an offset towrope and the Disco driving up next doors drive. Chris not happy at steering the car like that so a neighbour enlisted to help. He'as a good guy with an interest in cars and we've swapped tools and chat a few times.

As soon as the car started to roll he said it was not the gearbox but the diff as he could hear it. Now the Green Flag mad was adamant it was the gearbox when he arrived at the dead car and heard the noise - he had to "diagnose" before doing a recovery, and then said he was certain it was NOT the diff as it made no noise when being dragged onto the flatbed or rolled off.  Once it was home I never ran it again for fear of doing more damage and started the search for an AR35. I now have conflicting opinions...   So

Plan C (or D, E, F lost count now). Jack the back end up, disconnect propshaft at gearbox end, run engine and gearbox and see what happens.

If all quiet disconnect both halfshafts, reconnect propshaft, run engine, gearbox and diff, see what happens.

Seems the guy up the road referred to in post 13 might have been right all along.. b******d   

Start searching for a known good diff for a 3.2

The diff on it is a second hand one of unknown mileage fitted in May 2012, some 42,000 miles ago

[Kevin Wood]

Surely if it's potentially lost drive at the diff end you just need to look underneath and see if the propshaft is rotating?

[Sir Tigger KC]

Jack up back end with front wheels securely chocked.  Gearbox in neutral, handbrake off and see what happens when you try to spin the rear wheels.

To be correct title should read "Royally p****d off of Wootty Bassett" 

But seriously Mr E, if you need any help this week, I'm available evenings or Sun morning/evening 

Just give me shout, you have my mobile number 

[Shackeng]

Sorry can't offer to help this time Nige, as we are off on our holliers this week. Good luck anyway.

[Entwood]

OK .. am now Royally and seriously P*******d off, but sort of relieved as well ..

Jacked the back end up and crawled underneath .. and its not the gearbox or the diff ... I saw this .... (wheel removed to take the pictures)









All bolts present but obviously undone, looks like the internal "dome" of the joint is quite badly dented...... the bolts were last touched by me when the diff and drive shafts were replaced 42000 miles ago, AFAIK they have not been touched since so why

My intention is to do up all the bolts the run the car whilst on axle stands to check for any weird noises from gearbox/diff but I expect none,

now I need some expert advice .....

What needs replacing ?? Something must be damaged inside the CV joint given all the grease that's leaked out and the shiny bit I can see on the "dome" so ...

Complete replacement driveshaft including CV joint ?? or just the CV joint (Haynes implies it is replaceable on its own?) what about the hub is that going to be damaged at all ??

How easily does the drive shaft come out of the diff ?? as to get a better view of any damage I think I need to take it right off and clean it up ... Haynes implies its an easy job ..... last time we had the diff right off so access was far easier

Any advice gratefully accepted

If only Green Flag man or myself had got under the car and looked PROPERLY .... my excuses are a) I believed him, b) I was worried about getting a tow car for the holibob ..... c) I was in a suit at the time ....

How TF has that happened  ?  If you need a shaft/joint give me a shout 

[Doctor Gollum]

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.

[RobG]

If no hub damage Nige, whack another driveshaft on (must be from a V6 though due to bolt pcd`s)

Don't doubt it, but for all 6 to come loose... presuming that they're all intact

[Entwood]

Now beaten by the light ... or lack of it !! 

All six bolts are present and intact, although two are slightly out of true and will only do up part way, one is proud by about 3/8 the other by 1/8 .. tried in different holes with the same result so I'm fairly confident the hub holes/threads are undamaged.

Turning the hubs by hand there are no noises or high resistance spots, so far.

Tomorrow I will jack the the hubs up a tad so the drive shafts run level and set the whole thing in motion and see what we will see....

Thanks for all the advice, I have no idea how/why all 6 bolts have come loose, and no idea over what time scale either... I am certain that we (me, RobG & Shackeng) checked and double checked everything as we did it.

Omegod .. if you have a "known good" 3.2 V6 drive shaft with CV joint and 6 bolts please let me know the price, including delivery, as I hope to be placing an order with you tomorrow morning !!

It will be an easy "fix" compared to the other 2 options that it appeared to be... just a shame that by the end of this I'll have spent the best part of £200 on a gearbox I didn't need, and all the hassle and work I've had other folk do on my behalf, for which I'm very thankful to tigers_gonads for supplying and delivering the gearbox and Daz for stripping it, emptying all the old oil, replacing filters and gaskets and the thrust washer. Still.... once it gets to me at least I'll have a spare if I ever need one, along with the exhaust gaskets and the 10 litres of ATF .... ho hum .....

I would change all 12 bolts (both sides) and all the reinforcing plates and run it if no noises are heard.

We have old E46 models do this (except they snap the bolts) and you normally find the reinforcing plates have "gone soft" causing the bolts to work loose.

Are they the "half moon" looking curvy washers between pairs of bolts ?? I wonder if they are available from VX  6 of those and 12 new bolts shouldn't break the bank .. and a replacement driveshaft/CV Joint from Omegod might see the job done ...  ?

My EPC gives:

and
