Are we talkin' sliders or condoms?
do you get vibrations with your sliders? (1 Viewer)

uhh...
just so you know...my sliders are covered and ribbed for my safety and enjoyment.

my issue is also only with the vibration not the audible, except for the occasional klank of the cat hitting when i torque the engine up!

Easy fix. Just unbolt them and move them a little...
Oh...they're welded on...nevermind...

The plan to put a vibration matting on the arms, and Ari's to put air in them will not change a thing. If you're getting a vibration (not a sound as in the sliders vibrating AGAINST something), then you need to make the changes I noted in my post. Filling with air doesn't change the mass, and matting is designed to change the mass of thin sheetmetal but will not impact structural steel.
It's worth noting that the sliders will not create this vibration. They may be amplifying one your truck is creating (drivetrain, tires, etc), but they're definitely not the culprit. So you might consider checking to see what the slider's are trying to tell you....
I should also make the comment that the 80s frame seems unusually prone to amplifying vibrations. I don't know why this is so, but nearly all of them I've been in have a slight freeway speed "jiggle" going on and a right size bump will make even a smooth one briefly jiggle. Perfect tire roundness and balance seems to avoid it a bit. Anyhow, based on that, I feel that the 80 frame does have a tendancy to oscillate easily. You guys with and without the jiggling sliders should share your spring/tire/shock combos - perhaps there's more of a relation there than anything as these components are by far the biggest contributors. What speed are you guys getting this. I'm now recalling it's low speeds, eh? Yes? No?

A possible solution may be to fill them with expanding foam, this won't alter the mass much however it will act as an internal vibration damper. Problem is if it doesn't work it's nearly impossible to remove.
Any possibility of some welding trick working ? SImilar to when you have a whistling pc of flat webbing on a roofrack , and you simply twist it 180° to eliminate any whistling .
What about welding a slender length of metal to the underside of the slider ... or diagonally .
I have no engineering basis for this sorry .. just a naive thought ...

Man, I have had a lot of different 80's with sliders on them and have never ever experienced this. Either (a) I am can't feel it (b) you guys are just to sensitive (c) just lucked out that the resonant frequency or the frame on my 80's were different
We can always see if someone here works at Boeing or some such place and then have a total frequency ananlysis done for all sliders on the market and then write an article for a magazine " The low down hum on 80 series sliders". That should do wonders for getting the 80 established as a hard core off-road vehicles.
Also note, that Schotts has not said anything. Obviously the 100 has a far superior frame since the 100 series sliders does not oscillate

That's a good idea. I did that on my swing arm of my motorcycle when it would leak ever so slightly at one of the bolts. So to eliminate it from filling with water, i filled it with expanding foam. This foam wouldn't add weight or anything, but it could deaden the vibration a little.
I am still going to try and put some of that really thin adhesive backed foam on the back of the mount for the slider. Also, but a little between the bolt and the frame, and put a little where the brake lines lie across the mounting bolt. It's thin enought to just smoosh up when you tighten the sliders down, but maybe just enough to create a little baffle area.

Oh, cristo, don't say that! I think its because he's working on the 80 now and not in the 100 much, so expect him to chime in soon, i hope!
I guess that's part of what we are, picky. Since the 80 is such a nice vehicle, yet capable, i don't want to compromise the comfy ride. It's not bad, but it is something i feel could be eliminated.

I can add to this rambling discussion that the sliders still resonate when covered in a half inch thick coating of ice. So those of you who were planning to fix this by coating them in ice, 
not gonna work.

Yes, if you place it right next to a cat-back exhaust system. Tone will change but it will still resonate.

wow, three pages on bolt on vibrators. Who woulda thunk it.

If we can put rubber isolator sleeves inside the coil springs, that will help with some resonance. Land Rovers do this in their springs as well as add rubber cushion on top of each springs (D-II models).

I didn't suggest putting air in them.....They already have air in them! LOLI was suggesting placing a rubber bumpstop between the slider and the body, [edited for clarity]so that the rubber is constantly in contact with the body[/edit]. The downside to this is that it will probably mar the body's finish in that local. However, I believe it would solve the vibration issue

The slider is never in contact with the body, or at least should not be.

Agree. Only place the slider should touch the cruiser is at the mounting point on the frame.
I know the slider isn't in contact with the body. I'm proposing to add a rubber "bumpstop" between the slider and the body. The reason I am proposing this is because this would be at the end of the unsupported load which is where I would imagine slider is vibrating. I'm simply suggesting sandwhiching a piece of rubber b/w the body(perhaps at the pinch seam) and the slider to act as a dampener.
I edited my above post to hopefully clear things up.
