Thank you Thanks28 for your reply. You're right about being a beginer. Either part ( the analog stick or the silicon block ) can make a difference. Normally the silicon block is the problem as it tends to shrink or loose its shape from time to time causing the contact points to slightly separate between each ends. This will cause an odd ball effect on the direction of the analog stick were to the left direction, it appears to move find but to the right it moves slow, or either way. Anyway, I was just trying to let them know that there is a fix without having to spend money on parts.
