Small story - demand - and also warning...

Hallihallo
So, it all started with a nasty cracking, at ground waves, at ranking with hit wheel etc.
Smart as I thought, I guess I'm going to get rid of the suspension.
Well, since I'm also stinking lazy and my brother didn't want to set his stage free, I'm in a workshop...
"The shock absorbers are in the bucket," said the guy - mhm..I thought, could be already...and since they are already stone-old...so replace.(but just run to Audi, cost 350,- per piece because of the four rings)....I'm going to Unger and see...Monroe..59,- per piece...fine...so built-in.
Oh yes, by the way (as already suspected) the discs had to take up *almost credit *g**.
All right, proud of Oskar getting loose - boa...braked horny thinking - but then: crack...knack...knack...knack...knack...
Yes, no shock absorbers - so up again on stage, more researched....
Look there - the crossbar, the joint - beaten out - great!
So what now? Research at the junkyard?! Used market?! - no time and no desire to catch any outcasts.
So again Audi..and another Kredi record..egal nu.
Called - "we have to order, the day after tomorrow it is there".
Well, from me - cracks already 5 days, two more I can hold out (I thought).
The call comes "You can pick up"...enemy!
So, get in the car - drive away..to the Audi dealer.. are only 3 kilometers - actually a pity, because the box still runs nichma' really warm...
To make it short: I came 150 meters, namely right to the next corner - there it was, and it was right!
Ersma "auweia" gedacht - dann ausgestiegen (was sonst?!)
So after I had all the courage together and opened my eyes... look at.. looks like in a comic movie, when a car goes out of breath, the wheel was hanging in the front left in the box - already fas funny, except for the fact that the wheel crushed my half fender.
So far so bad - I spare myself (you) now, because it is twice as long again :-)
Okay, Audi on stage and let's see...
Aha, bike has completely out of the joint..beautiful!
...and what else?!...drive shaft bounced out...looks kind of broken...and stabilizer unsightly bent.
(What would have happened if I said we were 20kmh around the corner instead of pasque pace? - Anyway, don't think about it.
Well, again to Audi?..neeeee
Junkyard two villages further called..."Did you happen to have Audi V8 there?".
"Jo, we - 89ers - came in the day before yesterday and still complete"
I wonder if happiness is in unhappiness? so drove there..Stabi expand and drive shaft....hagged... 100 Euros.. you can't complain..
Built-in - looks good (and doesn't crack anymore) but unfortunately strange sounds from the direction of the drive shaft....*Arrghh*
So, now to my question (finally): Is the drive shaft the same on the right and left???
If I do, I'll change them tomorrow at the junkyard...
If not, who has one left (left front)? ..and also room Cologne? PLEASE REGISTER!!
Next question: Is it possible to install this part wrong? (I don't know how) or did someone schoma put one in and there were nasty sounds and he changed what and it was good again?

Oh yes, and the morals..speak warning:
Dear people... when it cracks out of the direction of suspension...gell!

Schoma Merry Christmas
Oliver

PS: A few bags of pity would surely build me :-)
