The no-tools Bear latch TD system is remarkably effective. Time had shown that. But if it does have one fault, it’s that it relies on the tension fit between two parts – the inside of the latch pocket and the precise diameter and shape of the limb butt.
The best way to compensate for that is to somewhat custom fit each limb into each pocket…if need be. With most Bear TD limbs that’s not necessary. They slide right in and latch down securely and quietly. Occasionally, though, some custom fitting is necessary, which I’ve found is no big deal. Just do it.
The most common (although rare) occurrence is a very slightly undersized limb butt. In that case, I’ve found that a little electrical tape, duct tape, moleskin, thin rubber or even leather cut and stuck or glued onto the limb butts here and there will make the limb fit better and snugger in the pocket. And it will also usually eliminate any creaks and groans.
If the limb butt is a tad oversized (very rare), careful sanding of the butt where it binds can alleviates the problem quickly. Again, some thin padding can be used to eliminate any unwanted noise.
The Bear latch TD system is extraordinary, but like most things it can occasionally benefit from some tweaking.
