Noise when going over bumps

My 2006 uplander had so many problems since I got it.
 
Seatbelt of rear replaced, stablibility and traction control light on, steering rubbing.
 
Now, when I go over small bumps under a low speed, a noise like something loose heard from front end, and the steering is a little bit sensitive. Went to dealership, two intermediate shaft replaced, and the noise still there, they said they are going to replace the steering column unit, but not sure for it.
 
Anybody here had same problem?
 
Thanks for any info.

Tell them to leave the steering column alone and replace the sway bar links, they should of figured that out its common.

thanks for the reply.
 
Going to dealer tomorrow, and hope this time is final.
 
 

got the whole steering column replaced, and now the noise back again!

I had a  similar problem, but luckily it went away when they replaced an intermediate shaft. 

Three intermidiate shafts, two steering columns, one rack were replaced, just within 17 k kms.
 
and, the noise is still there.
 
This noise has been driving me mad.

I have a 2007 2500 HD with 17K miles. About a month ago it started making a Knock or rattling noise and cannot quite make up my mind if it is in the front or rear of the truck. When you drive over a bump it sounds just like someone hitting the under carriage with a hammer. Yep, it just drives me crazy and I''ve spent more than a couple hours checking for loose bolts or other components under the truck. Cannot feel anything in the steering wheel when it happens.

Thanks for the suggestion. I was just going by the original post "Noise when going over bumps" What would be a good section?

I agree with ktm521 on this one. We have 6 Uplanders at work and they all made noise going over bumps.
They all had to have the sway bars worked on in the first year at about 20,000-25,000.
I would take it back and have the dealer look in to the sway bar''s

Had same problem see my thread STURSU 9-6-2008
