Ok so polyurethane bushing should only use a special type of grease correct? this stuff: http://www.spohn.net/product.cfm?productid=1322

Second why do the front 36mm sway bar greaseable bushing sold from spohn cost $41: http://www.spohn.net/product.cfm?productid=1356

and these on hawks for a 36mm greaseable bushing cost $19: http://www.hawksthirdgenparts.com/inc/sdetail/7633

Just wondering about that and also i have a grease gun with grease in it that i use for my tie rods/idler arm/ball joints...i guess i shouldnt use that for polyurethane bushings correct?

If so ill just have 2 different grease guns...1 for the bushings other for the front end stering components.

Thanks
