944 Control Arm Failures

[JeffYoung]

I believe it has happened twice:

1. Volvo 142 valve springs and

2. Rear hub/disc conversion on the GM Quad 4 cars.

The others as Greg mentioned were shot down.

Seems like a lot of 944 guys do fine --- what are they doing? Loading the suspension differently?

I have seen many failures of the 944 control arms but I must admit they were the Turbo's. Chris C. would be the one to ask on the NA 944.

If the Volvo valve spring allowance ever happened, it must've been many years ago. There is no such current allowance, nor has there been for at least the past 4 years. The GM rear hub allowance however, is currently in the ITCS spec table "Notes:" column.

And no one has yet been able to explain how/why/when this came about. Seems there's no documentation on it in Topeka, just what's in the ITCS.
