issolating differential
As i know, the most of us, we have noise problem from the rear differential block.
the reason for than noise it may be from the weel construction of the diff and the vibration that transfered to the main body of the jeep.
i would like to know if anybody has issolate the rear diff from the main body and what kind of silent block has used for that.
Thanks in advance.

Re: issolating differential
I used squares of rubber cut from a tractor tire inner tube. I stacked them about 4 layers thick.

Re: issolating differential
I have had good luck cutting squares out of conveyor belt. Probably 1/4 to 5/16 inch thick. Somewhere around you there should be an industrial center with lots of conveyor belts. Just ask the management about having a section of the stuff they are throwing away.

Re: issolating differential
I also like your M274 Mule. Lots of nice mods. What did you put on the bed? I didn't know there were any Mules in Europe
Here is mine, an A-5. It is original with like 20 hours on the engine, but the alternator and electric start may have been added. The Army did the modification but not sure if mine was after that or not. The rubber cover just lays on the bed for protection.
We had one in VN to take us from Ops shack to the flight line, and also load all the rockets and ammo and M-60s. This is August 1968, Bien Hoa with me siting up front next to the driver.

Re: issolating differential
I purchased a small 5/8" sheet (a drop from a local supply house) and cut then drilled my own rear diff isolation mounts from "Delrin." A "Nylon-like" polymer. There is a noticeable improvement in the (lack of) harmonics from the rear diff.

Re: issolating differential
ohio mg man--do you think i could achieve a similar improvement with lexan, or perhaps the heavy rubber setting blocks we use in the commercial glazing industry? the blocks come in a variety of thicknesses, and are 1" X 3 " in length. they are very difficult to compress, as they are designed to support large glass units that weigh in excess of 400 lbs.

Lexan would seem a bit "stiff" for that. A polymer like polyethelene seems to work out just fine. Rubber seems like it compresses too much. I dunno. You can find conveyer belting with nylon cording in it for sale. It is a bitch to cut. Thick rubber is a bitch to cut no matter what. I liked the Delrin because it had SOME give and I could mill the holes on my Bridgeport and cut them to size with a bandsaw. It was not that expensive to buy..look for a place that has something in "small scraps."
