I get cracking sounds in my joints when lifting weights does this mean i should avoid lifting weights?

Not necessarily: There are a number of potential causes, so you might want to be seen for a specific diagnosis before giving up something you enjoy. One of the more common causes is crepitance, which is often associated with early softening of the cartilage in the joints. In that case you would probably want to modify your workout to avoid excessive load bearing on the joints involved.
