Screw, Electric Locking Hub Lock Ring (T20 Torx) 3 req.

Screws that secure the wheel bearing lock ring/slip ring (43532-60020) to the wheel bearing adjustment nut (43533-60020) to prevent the wheel bearing adjustment nut from backing off.

Note: These screws can be very tricky to remove if they have been in place for a long time and they will often strip the torx head out or break the tip off the T20 tool. 

Tips for removal: There are a few ways to get these to loosen off when they are being difficult: one method is to use a flat-ended punch with a relatively wide end (so as to not damage the slip ring surface or break the brass slip rings) and to strike the punch with a small hammer to impact the slip ring near the screw while another person is applying torque to the screw with a T20 torx socket on a 1/4" drive ratchet or a 1/4" drive mini breaker bar. 3/8" tools work as well, but 1/4” offer better control. The objective is to have the impact from the punch displace the ring momentarily, permitting the screw to turn. 

Another way to get the screws to back off is to use a hand-operated impact driver - and hammer the driver !!gently!! - as you apply loosening pressure to the screw - this has a similar but somewhat different effect to the above method. Using a hand impact driver does have the tendency to brake the T20 bits, however, so have a few spare T20 tips on hand (and buy lifetime warranty tools!).

Be careful not to apply too much force as these screws can strip the torx drive in the screw or break the end of the torx socket/screwdriver rather easily.
