So, from your answer to Plonk, you're talking about C4 (middle C) to E5 (a twelfth above). The squeak is almost certainly caused by something's being open above the RH 2nd finger, venting the air column to produce a new node, much as the register key produces E5 from A3.
A couple of things to try:
Play G with your RH 1st and 2nd fingers down, so when you make the jump, you only have to move the left hand. If the squeak doesn't happen, but it does when you move both hands, one of your RH fingers isn't covering when you move everything at once. It can be because the rings and the top pad on the lower joint aren't adjusted correctly. If, when the pad is completely closed, the rings are a little too high, your fingers may not make good contact. If, when you've gotten the rings all the way down, the pad is not fully closed, that's a leak. If the bridge keys aren't adjusted correctly, the whole lower stack may not be able to go down all the way. All might seem well if the leak check wasn't done with the two sections assembled (bridge keys engaged) and the fingers you actually use weren't pressing on the rings.
If it isn't the RH fingers not covering, then you need to feel very carefully as you play to see if you may be only partially covering one of the LH holes. You also need to pay attention to whether or not you might be bumping the throat A key or the G#/Ab key or even the LH sliver (D3/Eb) key. Opening any of those even slightly when you make the change of fingerings could trigger a squeak. Not completely covering the thumb hole when you press the register key could be a culprit, too.
The only thing about these LH solutions is that they'd also affect other intervals from open G up into the clarion notes. So would reed or mouthpiece problems, and probably also embouchure movements. If it's really only jumping to E5 (what about F5 or F#5?), it's most likely a problem with the top pad or the first two fingers on the bottom (RH) section.
I don't remember if you have a teacher. You might try to eliminate or confirm a RH issue by having someone else who plays clarinet reasonably well to finger the interval while you blow with a normally formed embouchure. Turn the mouthpiece around with both the reed and the keys facing you so you can put the mouthpiece in your mouth while the other player works they keys.
