My 2003 4wd sway when I drive over 50mi. I replaced sway bar links and sway bar bushings but it still sways… Nothing is broken, no noise. I don’t know what else to do except to replace rear sway bar bushings but I don’t thing it’s gonna make a difference… ---

Worn shock absorbers can cause a vehicle to sway when it’s driven at speed. Especially one as heavy as your Suburban. Tester ---

Check the ball joints. ---

I have a trailblazer, and never noticed what you describe when I had broken front and rear swaybar links. I would look elsewhere based on my experience. ---

Following an inspection of the front suspension, if the shocks are old they’d be next. My '95 Suburban did great with a set of Bilsteins. ---

If those are the original shocks, they’re due for a replacement. Yes, instability on the highway and in crosswinds is a classic symptom. ---

Worn shock absorbers, worn or improperly inflated tires, the wrong tires or wheels, are my top 3 suggestions. ---

Bingo on possibly worn shocks. ---

Shocks, agree. I’d check the front stabilizer bar bushings, end links and all the steering linkage just for good measure. If the truck hasn’t had an alignment in a few years, that might be due for a check as well. These trucks tend to sag a bit over time and the alignment goes out when that happens. ---

And check the alignment. If the front tires are slightly off from each other . . they could be arguing with each other over which one will take the lead. Are either of the treads worn oddly ? ---

Everyone has come up with the most likely parts that may be causing your problem. .Another thing to check, for a wandering steering problem is the intermediate shaft and its U-joint. These can get sloppy and allow for the vehicle to wander. Have someone rock the steering wheel back and forth as you watch that U-joint. There should be no slopin the joint. Any slop and it needs to be replaced. > **[Dorman - OE Solutions Intermediate Steering Shaft 425-176: Advance Auto Parts](https://shop.advanceautoparts.com/p/dorman-oe-solutions-intermediate-steering-shaft-425-176/15710059-P?searchTerm=intermediate+shaft)** > > Save on Dorman - OE Solutions Intermediate Steering Shaft 425-176 at Advance Auto Parts.

Concur with @Tester and @Mustangman , shocks is where I’d look first. My truck has the same symptom when the shocks are shot. While replacing the shocks/struts, that’s a good time to test for play in other components too.
