Well, finally received the Tera Disco Bushings, FedX had lost them & Tera sent me a new set ASAP,.... A little tricky installing them, removing the old bushings was with my Vice, had a little piece of wood with a perfect size hole to match the outside link bushing area, & pushed out with using a socket a dab smaller than the Bushing. It pushed out into the hole in the piece of wood. Now comes the install, they are like a donut,(inner hole on link is concave) so you can't just push them in, the trick the guy at Tera said, turn bushing sideways, hole facing left & right(horizontal) & squeeze it a little in Vice, then holding Link in your hand, push (Greased) open link hole onto the bushing(release Vice).. Then I re-used the piece of wood & socket to push in further(push with socket on bulged end of Bushing). Now you'll have 1/8 of Bushing Hole showing(up & down) in the Link end, so put a screw driver in the Bushing hole and rotate bushing(swevel it) & you'll feel it pop right in....now bushing hole is in proper left to right Bolt position with Link opening. I see why greasing them with a zerk isn't so great for getting into inner bushing area, the hole in bushing is so tiny it's best to just remove once a year & do it right. My little bit of noise is gone now.
