Just lengthened the chassis, now just about to get the prop sorted.
I have a Mercedes booklet which goes through the process of extending or shorthening a wheel base. They touch on the subject of the prop shaft. They say that you can go upto certain lengths without a carrier bearing (ie unsupported), and these lengths vary according to the thickness of the tube on the shaft.
I have a 90mm thick shaft, and they say you can go upto 1700mm long without a carrier bearing.
If you have a 140mm shaft, they say you can go upto 2300mm long without a carrier bearing.
Question that I have is the following:
Can you have a 90mm thick shaft from the gearbox to the carrier bearing, and then have a 140mm thick shaft from the other side of the carrier bearing to the diff? Or do you have to have both parts of the shaft at the same thickness?
Might sound a bit far fetched, but several mechancis I know said this is possible.
If so, then I may be okay, as I can keep my front section of prop as it is, then swap my rear section for a bigger shaft and pay some extra for it.
