Driving me nuts. Something is knocking up front. I've checked everything. All bushings seem tight with minimal movement. Checked lower and upper shock bushings as well. Also checked all bolts. I'm stumped. It's loud at slow speeds cover bumps. If I rock car side to side I can make it knock but can't locate!

2" springs with terrafirma shocks.

 

I had something similar. Turned out to be the flat plat on the bottom of one of the shocks was broken. Visual inspection everything looked good. I had to pull it apart to know for sure.

 

I had the same thing It was my shock
get the front wheels off the ground get a pry bar and try and lift the bottom of shock where it bolts I bet the bearings are gone

 

curious: what 'bearings'?

 

where the bolt goes through the shock itself

 

so the shock bushing. I checked those but i will agian.

Terrfirma shocks only last 10k miles?

 

The lower one where the flat plat goes through the hole
