Title: clicking noise in my rear end...
Post by: pinto bismol on October 06, 2014, 05:00:46 PM: no jokes please!
I hear a clicking noise when I accelerate. Sounds like a playing card in a bike spoke. Just started a few days ago. Nothing dragging rubbing or loose that I can find. Any ideas?
Thanks!

If u-joint then it will be fairly high frequency to match the u-joint spinning which is faster than rear axles turn. If slower then look for something as simple as a rock stuck good in the tread, that can do it.

Check for something rubbing against the driveshaft or a wheel/tire/brake

Bought some new u-joints and will attempt to install them this weekend.

I've had a clicking speedo cable before but my needle would move slightly with the tick tick.
