Yes I have the amazing Ital axle in 3.6 built up by SP Components (Tracsport) for Caterham's budget line of scholarship cars in the mid 90's.
These are famous for having the outer berrings welded to abate shaft egress whilst curbing on track. Apparently the curb rumble strips are enough to dislodge the pressed bearings.
This of course makes the removal of half shafts an issue which makes upgrading the differential an issue as I can't remove it.
In all fairness, I wish to state here that per Steve S. at S&P who did those jobs, it was Caterham's build specification to weld those bearings. Also, none of those shafts were uprated.
Steve's advice was to upgrade the crown gear.
Rakeway had made a kit for Ital with captured and uprated shafts, and have been hinting more were forthcoming for a few years, but nothing yet.
I hope this is useful information to someone, but on to my question:
Is it possible to separate the nose, or diff carrier, from the main tube housing enough to drain the oil and any other bits that may be loose in there?
I know of one, so I'm asking.
And, is it possible to remove the shafts? I haven't seen these welds so I don't know if its a simple grinding job.
Thanks
Scott
