thanks for the info. guys...UPDATE: on my dime, i R&R the front & rear drive shafts, truck road alot better, i knew this & told this to the mech. for years
. the mech. that installed them pointed out to me that the universal joints were shot...i inspected myself & the one on the right front was ready to explode. he installed new after market ones but had to burn & cut off my hubs due to the fact that the DODGE DEALER when replacing the first set of joints failed to apply NEVER SEIZE to the hubs f%#&*^%$#. well, when hubs were off he pointed out that the ball joints needed to be replaced, i inspected & they were all loose, so more money & parts & finally the truck is fixed. next was suppose to be the recall H46 ???, dealer just called & said it was not a recall but an upgrade. anybody know anything about this?
