And it just decided to stop moving (driveline went crunch)

[Dean924s]

Driving home from a bid opening today. I go over a set or railroad tracks and then go for third gear. I very normal rev matched shift I might add due to this being the center of a sleepy town where the police know me. I let the clutch out and as I start to squeeze off the gas I here / feel this sickening crunch followed by the sound of things bouncing around in the back of the car. I now have no drive in any gear. Fortunately I passing by a local gas station I know. I coast in and park it in the lot. I call AAA and in less than an hour I am home (about 7 mile tow).

So here I sit thinking about it as it is raining out.

A little more info.

This was / is a 951 open diff trans.

Half shafts are in place and connected. I had them out about a month ago and inspected the CV's and re packed them. They were in good shape.

I can feel the sync-rows working when I shift it in to gear.

You can shift in to gear with or with out the clutch. and there is a little bit of noise coming from the gearbox when it is in gear.

The clutch feels like it is working properly

I have had R&P's go before and this did not feel like that. The bucking crunching and random engagement you get when that happened did not occur.

There were no warning sounds oddness of any kind.
This was more.. .. well quiet. Just felt a crunch and there was a little bit of that sound of metal bits bouncing around and then all was quiet from the trans.

So any bets?
Output shaft on the trans?

R&P? I dough this as I have been very nice to this trans and it is a 951 unit.
I have not hammered this trans at all. I have broken enough of them in the past (when racing) that I have that out of my system. I have not had this trans on the track

Something in the box grenaded?

I guess I am going to have to look at fixing the other trans I have in the shed. It needs the carrier bearing replaced on the driver sides output shaft. It is also an NA trans and I like the gearing better than the 951 unit I have been using for a while now.

I guess know what I am doing this weekend. Some quality time with my 924s.

I'm hoping you just crunched a CV Joint (Except for they usually go with a bang - unless all of the bolts fell out).

Look in the inspection hole at the rear of the TT and see what's up. That should pretty much answer your questions.

Good luck, Keith

Recent clutch or an old rubber centered disc? Clutch will still work, but might explain the "crunch"

Open the drain plug and see what comes out. I'm betting shiny metal pieces and that'll tell you what happened. Something broke.

The first thing is to inspect the connection between the train and the impeller shaft. I am assuming that this will be good but who knows.

I have replaced the clutch a while back so I don't think that is the issue and from the fell of things it appears to be working. Also the "bad sounds" I heard were from the back of the car. I am betting that it is the pinion shaft. From the feel of things I am getting power to the trans. I can feel the syncros working when I shift gears. I am just not getting power to the wheels and since this is a trans from a 951 the gears on the R&P should not be the problem. I will know a lot more when I get it out. I am sick at the moment so fixing this will have to wait a day or so.
