RE: Poly/graphite bushings

[David Bailey <bb64d440@xxxxxxxxxxx>]

Hi Steven and thanks for your clarification to my question of Poly bushings. After reading other replies I gathered the difference between bushings was the use of term urethane vs. graphite in the product name. Graphite of coarse possessing its own self-lubricating properties would eliminate noise. And that the bad wrap of squeaking was somehow inadvertently passed along with the new polygraphite name. 
And thanks for your word of caution concerning the strut rod bushings; I’ll keep that one in mind! And as for the ride qualities, I personally prefer a firmer ride instead of a soft boulevard cruiser. 
No, I did not see the show Jeopardy that night (I don’t watch it because those people are way smarter than me and I get to feeling inferior! ;>) what was the question?  Chrysler / Mopar related? 
 
Thanks!
