Black Macbook 2.4 Trackpad jumps, drags not responsive - Solution?

[haze324]

I've been searching the net for a solution but no luck. I have a late 08 Black Macbook 2.4ghz and the trackpad feels extremely rough. It does not look worn out one bit, but i have to press pretty hard and "push" the cursor. On the other hand my girlfriend has the same model in white and here trackpad feels like silk.

Whats the best solution for this? Is replacing the entire top case my only fix?

I apologize if this question has been asked before.
Thanks

Reset your PRAM first. Then consider replacing the top case. After doing that reset the PRAM again.

Thanks, yeah I tried that....played with all the settings too. Its the actual feel of the pad. The one my girls white one glides so easily, not mine though. Ok so replacing the top case might be the solution.
