probably bearings i take it, if so i need them and/or lube suggestions for temporary fix. thanks.

still has same power.

yea, sounds like bearings. try some kroil or something.

what is that stuff, and where can i get it. good thing you finally changed your avatar.

I agree with you...the bouncing , jiggling kid....was becoming anoying.....sorry squee

quite alright. after a year i became tired of it to. anywho, kroil comes in a orange can and i think walmart might have it. if not some marvel mystery oil might also work.

Sounds like a bearing problem or something in motor. You can knock the motor apart if you choose to.
