bushings for custom fab.

[Timber]

That's what I meant--it just seems too simple. Does it sit higher or lower in relation to the stock mount? I would presume higher.

 

[XJ_ranger]

It doesn't move around but how is it different than the stock one?
The stock one is still only rubber that is about 3.5"s wide.

Ive never seen a stock aw4 tranny mount - so I can only speak for my stock AX-15 tranny mount -

its about 6" wide, and has rubber all the way across - as opposed to a 2.5" bolt through a single rubber bushing...

I know that its meant to deflect, and I know you are running some lower gears in the t-case and axles than I am - just wondering how wear life and movement has affected your particular setup.

it just "looks" to me that it would deflect more than this piece -

good idea and a very straight forward solution though!:flipoff:

 

[BrettM]

you dont have any problems with the trans moving around? seems like it would want to rotate around that one point...

but that sure is a very simple solution to a custom tranny mount...

rotate?! around what point?

think of the 2 motor mounts and tranny mount as a tripod holding up the drivetrain. each individual mount needs to do nothing more than hold up some weight. (this is slightly idealized, but that's the principle at work)

Jes doesn't have an AW4, he has an AX15. And besides, the AW4 mount looks the same as what you have pictured there.

I would confidently wager that Jes' mount provides less deflection than a stock mount. With a leaf spring bushing there is a much smaller amount of rubber between metal-on-metal than a stock tranny mount.

Actually it deflects less because there's less rubber to deflect. With the stock mount I remember seeing my twin sticks move around quite a bit when I got on and off the gas in low range. They don't seem to move around as much any more and as far as longevity, the thing is still fine and has over 20,000 hard miles on it.
Plus YJ bushings only cost about $10.

I ran one like this for 1.5 years, with an old-ass OEM rear XJ spring bushing, with a stroker, and it deflected no more than stock. The mount is narrower, but the rubber is stiffer. I think you get some more vibes, but not noticably more.

Yes, it sits higher because I moved the back of the drivetrain up almost 2 inches.
Notice that my cross member is not below the "frame" rails.

doesn't the tranny sit closer to the crossmember? allowing you to raise the crossmember 2 inches while raising the tranny less than that. Do you know how much the tranny was raised?

Yes.
Yes.
Don't know how much the tranny was raised but the output yoke was raised almost 2 inches.

 

[BrettM]

Yes.
Yes.
Almost 2 inches.

you're so talkative :kissyou:

I was slow in comprehending what you typed.
I had to think about it and edited my reply.

I'm envious of the ease of raising an OEM manual box in an XJ tunnel. Slightly more work to raise an NV4500 2 measly inches.

Maybe I'll go back to the Peugot?

 

[Jes]

Maybe I'll go back to the Peugot?

That would be HOT!

 

[CRASH]

Until you see my new design. It's the trans mount that isn't.

Here's my new one, the bushing is a 1.5" OD Wrangler unit.

 

[waxer]

Nice welds Crash. What type of pattern are you using to yield those results?

I'm fond of a crescent moon pattern and inverted J's myself, but am always open to new ideas.

 

[CRASH]

I'd say close to an inverted J when doing .188 or .25 plate.
