Update on repair.
We couldn't find any OEM seller for the axle using drum brakes. Plenty selling those disk brake versions, brand new.
So we bought from a scrapyard second hand.
It cost us 75 £ and was local, so went and picked up
Delivered to the workshop.
However the axle from scrapyard although in good nick, came with almost all parts attached, such as drums and brakes.
The workshop is charging us additional 100£ for removing those unwanted parts and strip the axle for being able to fit.
It would have been cheaper to buy a new one which costs about 140 £ but are those disk brake types.
Lesson learned. If you buy axle from scrapyard. Ask them to strip it and give you only the axle.
Total cost to use will be 525 £ including fitting charges, additional parts and other costs as mentioned above.
