pedal problem

How old are the cranks?

Also note that the threads on the pedals are not the same - the right has a "normal" thread, while the left is "reversed". You might have damaged the threads when trying to screw the pedals in.

I think I pretty much found the problem. The threaded housing that the pedal goes into on the crank arm is loose. I was able to stick my finger in it and move it around. Anyone ever replaced this before, can it be replaced?

I never saw a threaded housing for the pedal on a crank arm. Customarily, the pedal screws directly into the crank arm.

A photo of the situation would help immensely.

Sounds like you have carbon fiber cranks, which tend to have metal inserts for the threads. That's a tough fix. My gut reaction is to discard those cranks, it's a highly stressed joint, and it'd be hard to get a glue to fill the gap.
You'd pretty much have to pull the insert out, clean up the surfaces, apply a glue, maybe some CF/FG flock, then reinsert while retaining the correct alignment.

If you can't pull it out, a crude fix would be to dribble a runny version of superglue into the gap and try to get it to wick/work its way in.
A high-tech version, but crude technique, would be to rig a vacuum pump to pull a casting epoxy through the failed joint, and then cure at an elevated temperature.

Yes, I think he does. Saw his post with the title "Wickwerks crankset and rings" posted yesterday.

Does anyone have any experience with the wickwerks crankset and rings. I am looking to purchase a 53/39t to replace my fsa k force crank that is worn out.

Indeed, the metal threads may have come loose off the carbon crank.

yes I currently have an fsa k force carbon crank. It is the metal insert that is loose.I may try and fix it and use the crank as a spare. It is not currently hindering my riding but don't know how long it will last.

Replace your pedal to a new one.

The problem has been fixed. I had to get a new crank. I called fsa regarding the warranty and told them what the problem was. I was told that my crank was past the warranty and that there was not really a way to fix the problem. The problem was the housing in the carbon crank arm where the pedal screws into worked itself loose.

I have SRAM Force Carbon Fiber Cranks and I'm experiencing the same problem. The metal insert for the crank thread has come lose and there is quite a bit of play in the crank. I am a heavier rider, 210 lbs and have had the bike for over 5 years. I've never had this happen before so it makes me a bit leary of buying carbon fiber cranks...

I got it fixed. I put some gorilla super glue in the gap. 500 miles and still holding.
