my problem is not the tires it makes u marks from the axel shifting back and forth, i dont know what it is?

I was on the Mass Pike driving about 60-65 mph next to about a 2005 3500 dually when it went into a wobble.It was crazy how much the tires were jumping around and squeeling rubber.But it must make most if not all front suspention worn once this starts happening.It was truley frightning to see how violent and extreme this wobble is.That reason alone is good enough for me to stick with the short commings of GMs IFS.

Read through the thread listed in my signature. It has everything we have found to date that causes steering and front end issues.

get the alignment checked could be your caster is off

I've gotta steering box brace and a reman. Steering box coming. I'm gonna put them on this coming weekend, and getting my front end aligned. Hoping this is gonna help

to my suprise it was the tires that was wrong with it it doesnt wobble no more, i cant believe the tires made it do that but thanks for all the help

Must have broken a belt inside the tires. Happened to my buddys 18 wheeler on the steer axle. What it goes into a death wabble with 80,000lbs its skeeeetch!:scare2:

Or the tires were not balanced correctly... I have seen that a few times

it could have been a combination of both they were just about shot

I had the same problem in my 03 it was inner tie rod... i would be driving down the interstate hit a bridge and it was horrible.... the front ends on these trucks are shit ... but like other people say i bout a cummins not a dodge.. and honestly you have to physically check all the joints by hand ... i took mine to the shop and they must have been stupified cuz they said the tie rod ends were ok... i checked it my self and one was like completely gone
