The replacement joint I have to replace has a boot that looks like its not got much life left in it, so I was thinking I could take the boot off the inner part of the old joint and replace it with the outer boot of the new joint?! Does this make sense?
Well you have me confused...
The inner CV joint will be different to the outer one.
If you're going to the trouble of swapping them which I think is not possible why not replace both.
They won't be the same, the inner may well fit as the outer and vice versa but as mentioned by aujopimur why bother, CV boots are quite cheap, also they perish so reusing old ones that are still intact is not good practice at all. Also I doubt the inner will fit as an outer as one side of it probably is not wide enough.
Yeah I think I'll just replace the boot. I suppose there are some things you cant scrimp on!
