Im going nuts... I have a 96 Ram 1500 and swapped in a 1996 Ram Dana 60 with 4.10's in the front and a rear 2001 dana 60 fullfloater with 4.10's. All I had to do was shorten both drivelines and everything works perfectly (LOVE the braking power). EXCEPT, I feel like something is hitting the drivers side floorboard (like loose exhaust)... Anyway, I checked everything and it seems tight. Has anyone experienced this? It happeneds on the road at regular speeds, on the slightest bumps. Same happens after I installed new shocks.
