How can I repair my indesit WIE 67 wahing machine?

My machine washes fine and does slow spin ok but when it goes faster it bags and makes a really loud noise. There doesnt seem any loseness of the drum but someone mentioned shock absorbers if you think that is what is wrong are they hard to replace. I cannot aford to buy anew machine or pay a repair man my brother would do it but he cannot do any heavy lifting. Can you help me PLEASE????
