Thumping Front End Sound

How many miles on the truck? After they changed the intermediate shaft, did it help for a little while? The last thing that was changed on my truck was an upper ball joint and the idler & pitman arms. It helped out for a little, but now the popping is back. (I don't seem to have the rattle anymore though) I will be making another trip to the dealer here soon to see if the can find something else.

Do you have side bars on the truck step bars, sometimes when they are not alligned right when moving slow on pavement and turning the frame will twist slightly and the brackets will hit the frame, look for a rust spot under there where the bars are wearing.:thumbsup

thumping

I have 5 gm trucks suburbans and 1 tons they all have had intermediate shafts replaced for this problem at least twice. Just got my wifes 03 suburban out friday for its third time replacement it only has 60,000 miles on it.

is it a 4x4? Ive got this clanking and in some corners it will thump, and its my ball joints, this is a dodge of course but it might be the same thing on your truck
