Worn out T-case chain

I might be completely off, but wouldn't a burnt VC act as an open diff, thus sending all the power to the front and resulting to the car not moving?

[nando]

with the front driveshaft disconnected, yes.

[duffyboby]

so running the car without a front driveshaft will destroy the VC and eventually the car will not move any more, I got awfully confused about this with the argumentation going on, I thought you could run an iX without front driveshaft, with a good VC, without any problems, except for the danger of the splines rusting out, obviously. Ive seen many go without problems.

[nando]

no, it probably won't destroy it. it just puts a load on it. the biggest load would be during acceleration, at a cruise it would be small.

I know several people who've done it before for years without issue.

So that settles it, thanks.

Like I mentioned to SPDACRM3, I would never have thought that the VC could take that kind of waste heat output for long. Educated.

It probably depends on how hard it's driven, as the amount of waste heat it develops is proportional to the product of RPM drop and transmitted torque, both of which depend on applied torque.
Apply more torque, develop more waste heat... get the temp up high enough that the internal pressure pops a seal and it's done.

However, even with a seal popped it's going to retain a small amount of fluid... I don't know if that would be enough to have significant torque transmission or not.

[nando]

agreed

I don't think it will work if the seal pops and fluid comes out, it might retain some torque but the car wouldn't move very quickly and it would probably cause a cycle of more heat/more leakage.
