@swampies, my GLT failed earlier this year due to a leaking power steering rack.
The frenchie MOT guy condemned the rack!
I luckily managed to source a 'dry' but used RHD rack here (via a frenchie Volvo forum I use) for 90€
I had it fitted by a garage (too much for me) for 200€ .
Parts for Volvo do a rack repair kit, for abou £30 ish. Apparently a pain to fit 'on the car' but easy off. I left my kit with the mec' , but he didn't fit it! Not sure why, but I got a refund...
When I was on the hunt, Salvo in Derby had a used re-con one for something like £110 delivered ( in UK) . Also forum member Rip33sta (or something like that, sorry to him of that's wrong) had a good used one for about £90.
Good luck and keep us informed of how you get on
