strange noise

I have 93 blazer 4.3 and when i go to first start it up it has this knocking noise like something is hittin something and it only does it for a while n then i don't hear it again but lately it has been making the noise only when i reverse...does anyone know what could possibly be my problem? it's a rather annoying sound, thanks.

RE: strange noise

Flywheel may be loss or cracked. Check to ensure that all the torque converter bolts are tight on the flywheel. These will sometimes back off causing this issue.
