Early Sportsman owners….suspension squeaks

2003 500. Obviously these bikes have minimal zerk (grease) fittings. The previous owner had all the suspension bushings replaced. but man are they noisy. I have soaked them down with silicone spray and will probably end up loosening, respraying and retorqing all of them.

Is this just inherent with these bikes with only a few grease points? SO far I dig this thing but man is it noisy lol……starter bendix, suspension, steering.
