Toyota: Help: Seatbelt retractor spring problem

I posted recently to this newsgroup about a seatbelt retract
problem I've had with my 1993 Corolla.

I removed the retract mechanism to wind the retractor spring,
but there seems to be something wrong with the spring--it won't
hold tension. I wind it up and it works for a bit (though I
don't think I wound it as tightly as I should have), then gives
a buzz and spins down to where it has no tension.

Should I just replace the entire retractor unit?

Thanks,

I had the same problem with my '98 Corolla. The seatbelt was replaced, but
the problem returned. Then a peice of teflon tape was put on the seatbelt
loop to reduce retraction friction. It helped, but not to my satisfaction in
the long run.
