[Steering & Suspension] Rear Wheel Alignment

[Nice4dad]

Fortunately my car is performing well, but have been approached by a neighbour whose B9 has failed the NCT (equivalent to UK's MOT) with rear 'side slip alignment' out of limits 20/m/km to the allowable -18m/km to +18m/km. They have had the car serviced who report that nothing looks to be worn and recommend replacing the rear axel.
The car is 2012 vintage and has covered 122,000 km. Its also been modified for wheelchair access.
As you guys are aware replacing the rear axel is a major job in terms of parts cost and labour. Is there anything they can have checked before undertaking such work, (or scrapping)?

I'll admit I haven't looked, but I thought the B9 was a conventional beam axle with big bushes at each end? (the older models have some sort of torsion bar with bearings)

Why not replace the bushes? eg https://www.autodoc.co.uk/meyle/12851436

Hi Shutu, thanks for your reply. Thing is that the servicing garage have reported that nothing is worn. The owner has received some information that Citroen Ireland will undertake a modification to mill a component between the axle and hub to correct the alignment for a cost of 150 Euro. He has heard that Citroen have done quite a few of these mods particularly on Berlingo vans. He is in touch with the local main dealer on having this done.

Interesting. Sounds like the axle is marginal for that test, and Citroen know it, as 150 euro for that amount of work is pretty cheap.
