V6 Bora 4motion Gearbox went Bang! Literally

[Siggers]

Hi Guys,

Was driving my newly acquired bora to a mates place for a BBQ, only put 134kms on it since I bought it and it drove perfect, anywhos, it started making a noise from under the car, guess it sounded like a flat tire, pulled over looked over the whole car, everything looked fine, but I pulled the haldex fuse anyways, the car made no noises when I started back up, anyways I decided to take it home, in the way there a different noise started then immediately it made a huge bang from under the car. Smoke and stuff from out the car everywhere, I pulled over oil over everything, checked under the bonnet and had a squize, looks like where the shaft comes out of the gear box to the rear wheels the housing is broken/cracked. Once on the tow truck yellowy oil poured out everywhere.


So I guess I would like some insight into the issues, is the unit on the side of the gearbox able to be pulled off? And replaced or is it a complete gearbox replacement?

What could have happened?

Any ideas, information, even speculation on the issue would be of great help.

Looks like the bevel box has let go.

I have a complete low k gearbox in the garage to suit if you decide to repair the car.

Where are you located?

You can separate just that part. I did it about three months ago.

I've got an angle / bevel drive from a mk4 r32 (was attached to an o2m 6speed box) if that will be of any use.
Heavy little bugger for what it is.

Thanks guys, it's raining ATM so hopefully I can take a proper look soon, after some research I am hoping it's the bevel box, and once I look into it a little further those that have offered assistance, I will be in touch.

It does drive forward and backwards, as I drove it on the trailer and off it again, hopefully a good sign.

Here is a few pictures of the damage

I have the complete gearbox and at a pinch I could deliver it to Brisbane. Don't know what it is worth and would be happy to take suggestions from forum members as to a fair price. You can pm me if you don't want to go public with your suggestions. Siggers I will pm you just so you can see how it works.

Hi All,

I am really struggling to get the bevel box out, someone put it as oh it's just 4 bolts and it basically falls out, well, I have undone allot more than 4 bolts, and I'm no closer to getting it out then those first four bolts, the part I seem to be stuck in it the prop shaft/flex joint, I think once I figure out how it decouples from the bevel box, I should be right. I have the rear half of the exhaust off, centre cv disconnected, but I can't see how getting to the bolts that attach to the joint would have enough space between it and the bevel box and there seems to be not enough space without dropping the sub frame to get at the rear of the joint.

Any help on this would be greatly appreciated.

You undid the 3 spline headed bots from the prop into the back of the bevel? And that deep set 6mm allen bolt I showed you?

As well as the 4 m8 allen bolts.

It just pulls off then.

[Siggers]

Those spline headed bolts, there isn't enough space to get them out between the flex disk and the bevel box. This may be because the housing is very damaged. Unless you are suppose to somehow undo the bolts on the other side between the flex disk and the rear of the car, which would take the flex disk off the bevel box...

I'll pm you Gavin's number. He has been working night shift but I think he should take your call
