02 Denali with bad side to side sway at n over 55mph.....WTH??!!

[Renzo778]

Idk whats going on, after I lowered it I had a very slight wobble at high speed over bumps. but over the last few months it has slowly gotten worse. Now when I get to 55mph and I go over a bump or hilly area it sways real bad to the point where I have to let off the gas. Its lowered correctly. The only thing I haven't changed is are the front and rear sway bars. I would think that the stock ones would have been ok to keep and not cause this kind of problem. Not every1 has changed the sway bars that's lowered their trucks and I haven't read of this being a big problem. Possibly re-torqueing the rear sway bar links. What are the torque specs? Any input is helpful. Thanks in advance. Lorenzo

If it has gotten worse I'd suspect something worn out. Maybe the steering box getting loose?

Sounds like worn steering components. Check pitman arm, idler arm, and tie rod ends.

1) what kit was used
2) cut bracket off frame
3) which endlinks used?

check your front sway bar links. I had one loosen up on me and my truck swayed like crazy..thought i had a bad shock.

I have the DJM Lca's w new sway bar links up front. BT 5305 rear springs and shock extenders, djm sway bar links, Spohn panhard new BT shocks all the way around. Did the free travel mod 6months ago when I first lowered it. Ill check the front links when I get home this evening.

DI'd you move swaybar over?

 

[Renzo778]

Yes

 

[Renzo778]

I'm gonna try n tighten then rear sway bar links to see if that helps

 

[NORCAL SS]

No 30 lbs,max also make sure link isn't broken

 

[Renzo778]

No links are broken. Very frustrated

Sounds like a problem I had a while back. The rear most bolt on the driver side rear lower control arm/trailing arm was the culprit. Somehow the hole in the bracket was larger than the one on the arm itself causing it to move. So I got a bigger bolt and slightly reamed out the bushing on the arm and that's all it was the whole time. Literally a $3.99 fix.
Have someone stand on the rear bumper and slightly bounce up and down while looking at the trailing arm bolt locations. There was just a little movement there but it translated to quite a bit overall. I'm not sure I would have ever found it without the second person.

Did you resolve the issue?

 

[Renzo778]

I actually disconnected the sway bar from the links n shifted it over just a bit. Reconnected everything and it drives 90% better
