How to replace audio track in mpg file (3,4 Gb) by mp3 fies? Without loosing video quality?
You need to look at MPEG demuxing and remuxing tools for something like this. Premiere is likely not the right tool.
I see, maybe you know how to do that in Linux, if you did something like that?
I've never used muxers under Linux, but you can try mpegdemux.
Take a look at Elecard Xmuxer Pro, for example – but that costs $$$. Look here and you may find a good, free Windows-based tool.
