This noise drives me crazy. I've changed tie rod ends, shocks,Sway bar links,sway bar bushings,upper and lower ball joints(both sides). I ridden on my running board while my friend did circles in a parking lot. The truck has a rattle that's really only noticed at low speeds. Steering feels okay.

What could it be?

Could my steering box be bad?

I've read to install a grease fitting on my intermediate steering shaft and fill it with grease, but that seems to be a fix on NBS GMT 800 trucks and I haven't heard any similar complaints for my First Gen Tahoe.

Thoughts gents?

Why do you suspect the rattle is from the steering? Do you feel it in the wheel? Does it only happen when you're turning?

Most rattles I've encountered, if metallic in sound, are from the exhaust or 2 pieces of sheetmetal touching somewhere. Also, loose mounting bolts.

I got a rattle in my 95 at slow speeds on bumpy surfaces. And I too have replaced all the parts you have. I believe it might be the brake pads rattling in the calipers. I don't get down too many bumpy roads anymore so I kinda forgot about it.

Keep throwing money at it, it'll get better...

It's been doing it for what seems like forever, I would hedge it's not the Calipers or Pads Since I recently upgraded to SSBC Calipers and brakes and the noise was their before and after.

It's not quite like an exhaust rattle and I can't feel it in the steering wheel. It's kinda like a clunk rattle.

Even just typing this response reminds me how much I hate it.

I've been getting some frontend noise too, and I'm wondering if it's the control arm bushings. Mine are original and have 280K miles on them. It's too cold outside to investigate, However.

Will it make the noise with the truck on jack-stands, in drive and wheels turning at low speed?

Is this rattle constant or just over small bumps or...it wasn't mentioned?

Get it up on a lift or jack stands and go at it with a rubber mallet, hitting tires, control arms, bumper, calipers....anything to try and replicate the noise from gentle "impacts"

The rattle is mostly noticed at low speeds over bumps, I tried tightening my Trans Cross member as I had hear that could be the issue. But I noticed no change.

I can't get it to do it on jack stands.

I guess its possible its the control arm bushings. That about the last thing I can think of,but I've said that before.

I've never known bad Control arm bushings to make this sort of noise.

The upper control arm bushings are easy to check. Jack it up and grab the wheel at 12 o'clock and 6 o'clock. Try to shake it just like checking ball joints.

I dropped it off at a shop last Monday to check out and replace the lower a arm bushings-since you can't buy complete lower control arms for these trucks and I don't have a press to get the new ones it.

Well, they through it on the lift, tightened my sway bar end links and told me they fixed it.

1) I just tightened them after I adjusted my torsion springs about 3 weeks ago.
2) they clearly didn't drive it.
3)It's very obviously not fixed.

They also told me I needed brakes. I told them I just did them and that I would address it myself.
I checked the pads and they are fine. 80% life still in them. Do good shops exist?

So I'm still stuck. Is Tightening the cross member with a 2ft breaker bar enough? or Do I really need an impact gun to tighten them.

I'll have check the bushings myself if it ever stops raining in NY.
