The wheels on my son's train only makes clicking noises

SOURCE: the track ball on my blackberry 8310 stopped working.

No, but fortunately the trackball is not hard or expensive to replace. If you are technically savvy you can do this yourself. Just purchase a trackball on the internet. The trackball easily comes off if you put a small flat screw driver under the outer side of the chrome ring and pull if off. Let me know if you needed more help. Good luck

I have 2 John Deere 4010 traveling sprinklers and they both do the same thing. I took them apart and the plastic worm gear has flat spot on them. I am having difficulty finding replacement parts.

I would replace the gearbox, but it is a specific little tikes gearbox. If it is making a grinding noise, then the gears have broke.
You can find them at this website

Check your suspension bar and check your front strut assembly, jack up the side you here the noise on and pry against the tire to see if you have any movement between the strut housing and the frame, make sure the top strut nuts are tight, if they are next check tie rod ends to see if you have any play, next pull the wheel from the top and bottom to see if it's loose if it is watch while someone else wiggles the tire, you could have a tie rod loose or a king pin loose. Also it could be a wheel-bearing nut. Let me know what you find so I can tell you how to replace it.
