Hey guys, about 2 months ago i went from an 07 ram to a 99. The 99 is a 4x4 5.9L quad cab Larimie. So far I have replaced ALL ball joint, universal joints, tire-rod ends all 4 shocks, and track bar. Lately when driving I can feel something under the floor board. There is no real noise associated with the sound I can just sorta feel it under my feet. Almost as someone was under there tapping the floorboards with a rubber hammer. Hard to recreate it because it only does it on occasion I cant pinpoint other than just driving what makes it happen I have climbed under the truck there is nothing really under the drivers floorboard and I have tried to move or hit everything with a rubber mallet to see what has play or movement in it. Everything is tight and dry.

Any suggestions ???

 

did you tighten the shocks enough? they can cause this

 

Body mounts loose? Engine mount? Trans mount? Control arm bushings getting bad? Dwarfs hiding under there, and running away when you look? Sway bar links?

 

How do diagnose loose mounts, it could be the control arm bushings but they have zero play or movement when i give them hell. Dwarfs are something I will definitely keep an eye on possibly even set traps.

Did you notice a difference with that thing installed ? next on my list are the plenum gasket and a rattly cat but that may come 3rd if it works

 

All I can say is , that after making sure the front lower shock bolts were tight, I put the RS Ram bushing on , and I no longer had that clunk. Not saying that's your problem, as you need to check all the steering components. But it worked for me.

 

i drove it today it seems to do it when driving in a straight line at speed , my fender liners are missing a few screws because i removed some mudflaps. Do you the the wind could be banging the liners against the fender well and creating the problem ??

 

I doubt it, but anything is possible. Fix what you know is wrong first, then go from there.

 

lower shock bolts. torque to about 105# which requires some serious muscle and/or pull bar.
