You could even tow an iX on a dolly a few miles at low speed without causing any damage, but I would NEVER reccomend doing so.
Make up your mind already. Is the VC super-stiff, enough to keep from overheating with a driveshaft removed.
Or is it super-loose, enough to keep from overheating if towed with two wheels on the ground.
It can't be both (at the same time).


A good VC test video (if you don't rely on manual testing):

Dude, I don't know why you are haviing such a hard time with this. If the two output shaft are spinning at the same speed (the condition that exists with the front drive shaft removed) the VC is not doing any work.

If the output shaft are spinning at different speeds, the VC is working. So if you tow the car with only 2 wheels on the ground, the VC is working the entire time. The point I was trying to make is that our VCs are very tough and a brand new one could take a few miles of low speed towing without a proble. I then said to never do it. My reasons are, its not necessary, it aint helping anything, Maybe 3 of us have new VCs, etc., etc.,

I have experienced both of those scenarios plus the totally grenaded scenario I explained in a previous post.

for sure, the tourings VC is pretty much toast. what's amazing to me is the VC that I got out of my parts car has 224k and it still works like it came from the factory.

Same thing happened to me. Got the whole car for $300 too!

Yeah, if you drive an iX only on dry pavement I believe the VC would last nearly forever.

I think even you should realize there is a slight gap in your reasoning there...
See my previous reply for some pointers.

i wont debate over it, nor im going to explain it. im not a technical junkie.

but im am willing to confirm, that the iX can be driven with only the rear driveshaft present - this without damaging the VC.
you can also use only FWD, we had one occasion when it was needed to get the car on the trailer.

i drove with rwd the whole summer and so did a local touring (the front driveshaft splines were kaput), so does our local 500hp+ drag car - when it breaks another front diff or halfshaft (btw, the modified halfshafts tend to hold up now), so did a fellow e30 clubber.

however, demonstration locally is possible

So to summarize:

A car with a not working VC will not move with the front driveshaft removed.

A car with a working VC will move and drive normally with a removed front driveshaft.

So a working VC is required to drive without a front driveshaft, but the VC doesn't get a workout from doing so... why?

Yes, very interesting dilemma

It doesn't need to do any work at all if it does work. But then again if it doesn't do any work, it.. um doesn't work?

Very logical indeed



Curtis, are we the only ones that see a slight problem with this "proof"?
