This may sound like a stupid question but think about it for a minute before you flame me. Every irs car I have owned (except for front wheel drive models) has a 1 or 2 piece tailshaft with universal joints to accommodate movement of the differential. Every Commodore with irs has a diff bolted to the rear suspension cradle ie does not move as it fixed to the body. Why do they have universal joints? To my mind, they only need the center bearing which would look after any minor movement from mounting rubber blocks. Ideas, Suggestions?
