Finally replaced my front air struts w/ OE replacements
No longer hearing the noise from the top of strut which has gotten worse during the last year
Can't say I notice a significant difference in the ride/handling which is impressive since they were last replaced about 5 -6 years ago=120k miles
Currently have 220k miles on it (2009 AWD)
I know I could have saved $ w/ aftermarket, but I was a engineer w/ big3 and I've seen studies showing that aftermarket parts are often lacking
And since the OE parts have given me good service, I don't mind paying more
