They probably are bronze- one at each end with a steel sleeve in the middle.I've replaced these 3 times in 3 years, constantly tightening the through bolts to square them against the bushing and the sleeve. Already put a grease zerk in to help them survive longer. There's just too much force against the bushings with our terrain and driving style.A Heim joint won't get egg shaped anywhere near as fast. looks like I can buy a Heim for the same price as a bushing-still debating on 1/2" (space is tight on the bulkhead) or just go with a 3/8" I know will fit.
