Kevin, I just went through this same process on my 98 TA a couple of weeks ago. Those snap rings are much easier to install and remove if you use the proper snap ring pliers. I bought mine from harber freight for something like 5 bucks with 4 size adapters for differant size snap rings.
When reinstalling mine, it took a few tries cause although it may seem that the snap ring is catching the groove it sits in, it may be close but not actually in the groove. Also, if your not using the proper snap ring pliers, its possible that the ring could be spread too far apart to "snap" into place. If thats the case, just bend it tight again. Check to ensure that the ring is sitting in the groove all the way around too. If you have the ends in place but one piece is not fully seated, it can just pop out with pressure.
Good luck bud.
