mods are asleep so I'll post this hotglue fix for BBM Ironhide and Ratchet's loose hips. Hotglue just barely sticks to ABS and doesn't really stick to Nylon, so all you need do is to jam that hot goo into their crotch cavities then immediately press the mushroom pegs onto the glue while it's still hot. The excess can be easily pulled or scraped off. The remaining glue will form a rubbery bushing around the mushroom pegs generating a lot of friction.
Also tried doing it to the waist swivel but the geometry makes it hard to do.
