I have a GB270 with a suspect worn front drive shaft (knocking from front wheel area when turning right). Subaru want £467 for a new one but 5-6 week delivery is not good. Aftermarket parts appear to get bad reviews with them being poor quality and not lasting. I've not ordered one yet but I'm thinking the Subaru part is looking the best bet. Any comments or suggestions where I can buy one from please?.
