my left front seems to hit harder than the right side,rear seems OK , just the left front. steering wheel don't shake or anything funny. sometimes i can hear air, like a bleed-down or something from outside after i shut down, but not all the time. is there anything in particular that i should be looking for, i have new front shocks installed last year at a heavy truck shop when i had the unit serviced last year but they didnt find anything wrong and the shocks didnt make any difference .
