One of my rear axle shaft boots on my '85 300 TDT is split and oil is leaking out. I have been told that the boot alone can't be replaced, I need to replace the whole half-shaft. Since it just started leaking and the CV joint inside is still OK do you have any ideas on how to avoid replacing the whole shaft? I've thought of rigging and old inner tube and sealing it with a tube repair kit but I'm afraid the centrifugal force will be too much for it. Any ideas? Thanks.
