i will keep this simple.ever since having my h&r sport springs and herman shocks installed my car has made a irritating thump noise from the passenger rear end area.i put it on ramps today to see if i could find it and found nothing wrong,everything has proper clearance and is tightned down.all the springs do have the new isolators installed and my alignment chart shows everything in the green except the front cross caster which my alignment guy said there is no adjustment for that anyway and will not hurt a thing.this noise happens on smooth roads,rough roads,it even made it while backing up one night last wknd going 2mph.i did retighten the rear shocks top and bottom still does it.the funny thing is the car does not do it all the time as most of the time it's noise free and the ride is great.all ideas welcomed on trying to find this gremlin.
