ARB classic Fridge Mount (#*&^% noise) ?

[Elbert]

Hello group...

I've got a 1986 FJ60 with a wood deck in the back with a ARB fridge mated to what I think is called the ARB classic fridge mount. I've post some pics below, one of which shows where I've used a couple of large rubber door stops in an attempt to reduce the vibration at times I hear when the rear axle crosses a pot hole or hard bump. The noise is coming from this mount because I have removed the rear seat and when I remove the ARB fridge with its related half of the arb mount, the annoying rattle goes away , so its specific to this mount.

Ive adjusted what can be adjusted, no real change, I believe the mount half that attaches to the fridge is vibrating at some level against the other fridge mount half that mates to the wood deck. All bolts are tight, I cant replicate the noise by manually trying to move the fridge as its in there solid. I just today tried the door stops idea to see if that mitigate the issue and it does to some degree, but not in total.

In my R&D work the noise goes away if I remove the fridge and its related half of the ARB mount. All mounting bolts are tight and have not come loose. It does not appear to me that the fridge is moving around in its mount, but it does appear to me that the upper and lower ARB classic metal mount the (two halves) are vibrating or rubbing each other and so far I've not been able to fully stop or address that.

Has anyone come across a hard solution to this problem? (pics with notes would be great)

imo all you can do is shim it up. use some thin rubber to snub areas potentially rubbing. also make sure the bearings aren't sloppy.
for the money, this is a pretty cheesy piece.

yeah two welded up boxed frames that slide one on top of the other. it seems to rattle left to right and front to back. Even though you can't rock it when locked in the stow position sitting still (manually trying to leverage it), as I have it "wedged" now...but sound issues are still there. Far as I know the bearings are ok, there is not a lot of adjustment in this thing. I was looking around the ARB site a few min ago and it seems the present version of this has some re-design features. The rattle is a problem for me. I've wedged or shimmed the rear facing part with some rubber door stops, Trying to find something adequate to do the front in a similar manner. I think the problem is inside of the "square" where these things rub...offhand it seems rather a problem to put anything anywhere that would not interfere with the thing "sliding" and closing. Unless I get surprised this thing may be a "howler" and you just have to live with it. Nothing has really come to my attention so far at least, as to a good hard solution that resolves the problem (vibration left to right or front to rear)...causing sounds....where the top half of the frame rubs or can rub the bottom half of the frame. If this thing was outside or in a bed or on a work bed etc, would not be a problem, but in the cargo bed of a 60 or otherwise in a similar vehicle...the noise is a problem. There is nothing loose on this thing or the wood deck or mounts etc or anywhere...I've gone over it a few times to check for stupid stuff. I was hoping some type of wedge might solve the problem when moving....but even then I suspect that the two metal pieces are going to rub regardless.

Seems like the ARB people should go back to the drawing board and have it setup where the top piece that mates to the fridge....that when this thing stows for transport its locks down into a position where its not metal on metal and can't be metal on metal. because having a stowed position where these two metal parts are so prone to rub / vibrate etc, only promotes noise.

yea frustrating....I spent some time trying to resolve. Even if I give it a "wedgee".....there is still metal on metal contact.

i went back and forth on buying a slide. ultimately I built one. similar basic design. just using real bearing slides and aluminium.
