04 TrailBlazer Front End Knocking

Hi all,

I'm fairly new to this site. I saw some postings on my problem (front end knocking) to my 2004 TrailBlazer. Every posting says it's my end links. I've had these replaced by the dealer now 3 times. I've also had my passengers side lower ball joint replaced. (you know GM allows 1/8" movement in the ball joint..!) The dealer also checked all the front end components and said everything is tight. They also replaced my upper strut/shock bushings and that didn't even fix my problem. They attached listening sensors around the front end and heard it, but couldn't come up with the solution. They told me to live with it... Has ANYBODY else had this problem and the fix??? I don't want to spend the extra money on aftermarket endlinks if thats not going to fix things... My warranty will run out at the end of March.

It's driving me crazy..!! Thanks... junkyardog

my endlinks came loose a few times. They may have skipped them since they'va already replaced them.

04 Front End Clunking solution

Hi everyone, I thought I'd give you an update on my front end clunking... Everyone I've read says that then you go over bumps and the front end clunks, it's the end links... Well I have some more news for all of you... it might not be... My fix was the $12 pair of sway bar bushings. I went to NAPA and got myself a set of synthetic bushings and installed them this weekend. I took it for a test drive and no clunking... What a relief..! Previously, I took my TB to a Chevy dealership 4 different time and they could not find the problem. After MANY hours of looking, replacing end links, struts, ball joints, all it was was the bushings. GM told me that they hear it but could not find it so I would have to live with it. Unfortunately, the techs now-a-days look on a computer instead of trouble shooting the old fashion way...

Mike

p.s. oh by the way... GM says the struts are covered under their warranty, BUT the person who OK's the warranty calls the struts a shock which is not under warranty.

Hi
I am new to this link. I have read some helpful suggestions on this sight. I have an 04 trailblazer and had problems with the front end. Had a leaky strut. I replaced both but still have some vibrations when I go over bumps.

Have you tried wiggling things while a tire's in the air? Possibilities include anti-sway bar end links or bushings, tie rod ends, ball joints, upper or lower control arm bushings. Many items to get loose. A decent alignment shop can also help you diagnose things, if you're not a DIY mechanic.

I am having the same problem and have a good friend from a very reputable, national tire chain look over the envoy and could not duplicate the problem. It is a very subtle, but noticeable knock in the floor. My question, is when i upgrade to the Bilstein hd, what problems or irregularities should l be looking for? How do i know that the upper strut mount is bad. I am like the other guy who posted earlier, it is driving me crazy!!

Thanks

I bought the front end links and will install them this weekend. I will let you know if that takes care of the problem. Thanks for your help, roadie.
